Cayenne's Service to Improve Fuel Economy

Good day everyone, Cayenne here and today I am going to bark to you about how to improve your fuel economy. 

cayThe price of gas around the south bay has got people in Los Altos talking.   It seems that folks from Los Altos,  Cupertino, Sunnyvale and Mt. View  need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy.  

 

 First let's start with how we drive around CA. People in Los Altos may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster, too.

Another thing Los Altos drivers can do is drive more slowly - but only when it's safe. Sometimes on the freeway we drive an extra five ... ten . . . twenty ... over the speed limit. We do it to save time, but it only saves a few minutes out of maybe an hour long drive, and we may use 10 to 15 % more gas. Just leave a little bit earlier, save some money and arrive more relaxed.

Los Altos drivers can also try and combine all of their errands for the day into just one trip, rather than several. If you can put off a trip today that can be combined with one tomorrow, you can save some time and money.

Using your cruise control can save money too. Driving in CA at a constant speed really improves fuel economy. Be sure to only use your cruise control under safe conditions; you can look in your owner's manual for some good tips on using your cruise control.

Did you know that reducing the weight in your vehicle saves gas? Clean out the trunk or back seat from time to time so that you are not paying to carry a lot of stuff around Los Altos that you do not need in the vehicle. If you live in CA where there is snow and ice, clear it off your vehicle; it adds weight and messes with aerodynamics too.

Another tip is to avoid long idle times, which includes warming it up when you start. Modern engines do not require a long warm up to get going;  just take it easy for a few minutes.

Be sure to get a new gas cap if yours leaks or is worn.

Now, let's start talking mechanical. Bottom line - the better you maintain your vehicle, the less fuel you will use. It all adds up in a big way. For example, replacing your dirty engine air filter will pay for itself in improved fuel economy before your next oil change - and will keep saving you after that.

A clean, well-maintained fuel system really pays big dividends. A clogged fuel filter wastes gas. So does a dirty fuel system, grimy fuel injectors and plugged up PCV valves. A fuel system service decreases the gas you use, and increases the power, so drivers in Los Altos can't go wrong with that.

Some of us ignore our Check Engine light. But fixing the problem that caused the light to come on will usually save some fuel as well. It may be a bad oxygen sensor that can really rob your fuel economy.

And, it may be time for a tune-up. Tune-ups should improve your fuel economy. Don't overlook the routine maintenance items, like scheduled oil changes, transmission and cooling system service. Dirty or low fluids actually use more fuel. Just look at your vehicle manufacturer’s recommended service intervals in the owner's manual, or ask your Allied Auto Works service advisor for the schedule.

Don't forget your tires. Underinflated tires waste gas. And if your wheels are out of alignment, you won't get the fuel economy you need.
 

As you can see, none of these things are very complicated or expensive for people in Los Altos to stay on top of.  When you maintain your car properly, you save gas today and prevent repairs tomorrow.  Give Allied  Auto Works a call today and tell them Cayenne sent ya!

Happy Holidays,

Cayenne

Duke's Advice On Good Service and Good Fuel Economy With Allied Auto Works

 

dukeHey Duke here and today it's all Good.  It's about service and fuel economy and with the holidays just round the bend we could all save a little at the gas pump.  So let's get barkin'!

 

Most Los Altos, Cupertino, Sunnyvale and Mt. View  auto owners want to save on gas and seek our advice on improving economy. At Allied Auto Works, we are frequently asked, however, if it is really worth the extra effort. Just how much money can South Bay drivers actually save?

In today's Allied Auto Works article, we're focusing on the things you can do to improve your vehicle’s economy driving around CA. We'll tell you the potential savings per gallon of gas at $3.50, and we'll show a chart that also shows the savings at $3.00 and $4.00.

 

DOLLARS PER GALLON $3.00 / $3.50 / $4.00

TUNE UP 4%.12.14.16

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best mileage. A clean air filter means you get plenty of air. The fact that the air's clean protects your engine. That can save you up to 10 percent or 35 cents a gallon.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

AIR FILTER 10%.30.35.40

Fixing a faulty oxygen sensor can improve economy by up to 40 percent. That's a whopping $1.40 in savings per gallon. Bring your car to Allied Auto Works in Los Altos and we'll check your oxygen sensor.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

FAULTY O2 SENSOR 40%1.201.401.60


Chances are that if your oxygen sensor is kaput your Check Engine light will come on. Now, there are any number of things that could cause your Check Engine light to come on besides oxygen sensor problems. But if it's on, get it checked out as soon as you can at Allied Auto Works.

Here's an easy one for Los Altos auto owners. Inflate your tires to the recommended pressure. That could save you three percent or 11 cents a gallon. Even a little drop in pressure will bring down your economy, so check your tires every week.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

TIRE INFLATION 3%.09.11.12

Your vehicle has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced economy, or up to seven cents a gallon.

Another thing South Bay vehicle owners can do to improve that costs nothing is to toss the junk out of our trunks. In other words, clean out the car and stop hauling around non-essentials. Don't treat your vehicle like a storage locker. Dumping 100 pounds of extra weight adds up to a 2% savings at the pump.

So when you tell someone you were going somewhere anyway and they're welcome to come along, that's okay. But if someone tells you they need to come along and it's no harm to you since you were going anyway—well, now you can tell them, “Sorry, dude, but you're an extra fifteen cents a gallon!”

All joking aside, let's all do ourselves a favor and fatten up our wallets by practicing good car care and better driving habits in the South Bay and all over California,

 Duke

Duke Deals With Fuel Injectors

 

dukeDuke here and today we explore the world of Fuel Injectors, what there purpose is and what they do so............let's get barkin'!

 



The last new car sold with a carburetor in North America rolled out of the dealership in 1990. Since then, all new vehicles have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injection is a much more precise way of delivering fuel than carburetors. That translates into better fuel economy and power. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.

A few auto makers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure - hundreds of times the pressure of port injection systems. Although more complicated, direct injection technology promises greater power with improved fuel economy, so we can expect to see more of it in the future.

As you can see, the level of precision required of your fuel injectors is very high. They need to be operating properly in order for your car to run right.

High temperatures under your hood and variations in gas quality cause fuel injectors to become fouled with wax, dirt, and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. The design of each engine requires a specific spray pattern from the fuel injector that might be altered when the injector is dirty. When injectors are dirty, the fuel doesn't burn as efficiently resulting in poor fuel economy and loss of power. So it is important to keep your fuel injectors clean.

Skilled service technicians at Allied Auto Works in Los Altos can perform a fuel system service for you.  That is a fuel system service - not just fuel injector cleaning. That is because the fuel has a lot of ways to become dirty or contaminated between the gas tank and the fuel injector. A fuel system service starts with a fuel filter replacement. This filter cleans the gas as it leaves the tank. The various parts of the fuel intake system need to be cleaned from time to time to remove harmful gum, deposits and varnish. Finally, the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

 Allied Auto Works  uses a process for cleaning your fuel system that includes state-of-the-art cleaning chemicals as well as some old fashioned scrubbing. Proper maintenance of your fuel system means that you will spend less on gas, enjoy strong performance and prevent costly repairs down the road.

Well I hope you learned something today and until next time, this is DUKE! duke

Duke's Fuel Injection Advice: It Keeps Getting Better for Los Altos Drivers

dukeDuke here and I am going to inject you with alot information today on Fuel Injection and how it works.......so let's get barkin'!

 

Los Altos residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.

There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with airbefore it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the vehicle engine.

Direct injection engines burn fuel more efficiently than conventional vehicle engines. Some models can deliver the power of a V8 with the economy of a V6.

For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower.

Why the big difference in power? Direct injection systems allow fuel to be squirted into the vehicle engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the vehicle engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization. Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.

When fuel injectors get dirty, their precision drops off. The spray pattern won't be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and fuel economy as well as delivering less power to the engine.

Los Altos residents should understand that fuel injectors are not cheap to replace. Direct injection fuel injectors are even more . And we're talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.

So keeping your fuel injectors clean is just good auto advice. The best way to do this is to change your air and fuel filters regularly and practice other habits of good vehicle care and preventive maintenance. Cleaning additives in your fuel can also help.

If you do end up with gum or varnish in your fuel system, you'll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, Los Altos drivers will enjoy better fuel economy and their fuel injectors will last for a long time.

Duke's Fuel Saving Tip: Car Weight and Your CA Driving

dukeHey it's Duke again and you know what?  My Vet told me I need to watch my weight alittle.  Keeping me lean and mean will make me be able to go for longer walks  around town without getting tired.   Well you car can do the same thing if you watch how weight you put in it for fuel savings so it can go farther and save you money too.  Well I guess it's time to get barkin' about this subject!

 



Weight is the enemy of fuel economy. Everyone from Los Altos, Mountain View, Sunnyvale and Cupertino knows this makes sense.

Some of us in the Los Altos area carry a bunch of unnecessary weight, and I'm not talkin' what you see in the mirror.

Guys: sports equipment and tools.   Ladies: well, just take a look around the passenger compartment and trunk. I think my car has about 45 pounds of french fries on the floor.  Even the dog kennels in the back of your truck add extra weight.  Take them out when you don't need them.    Don't use your car like a storage facility unless you plan on dumping that stuff ASAP. 

All that extra weight wastes gas as you drive between here and there, and everywhere else.

Lose the junk and save some money.

...And you really only need one of those spare tires. 

Now where did I store all of my extra bones????.......better check in the trunk!  Til next time, this is your friendly Automotive Dog, Duke!

Cayenne's Guide to Saving Fuel: Get Rid of Dirty Oil

cayHello on this hot first day of summer, this is Cayenne and today I am going to bark dirty to you..... dirty oil that is and how to save on your fuel.  So let's get down and dirty and start bark'in!

 

A lot of us drivers are asking ourselves the same question lately: how can we save on fuel? Los Altos area residents are all cutting back, if not in fuel consumption, then in other areas of our lives.

Preventive Maintenance

Preventive maintenance is an important way people in Los Altos can conserve fuel by improving fuel economy. And one of the easiest and most effective ways to do that is to keep the oil in our vehicle adequate and clean.

Oil lubricates your vehicle engine and keeps it running smoothly. If you're running low, there is increased friction in your engine. Friction creates drag, which means it takes more fuel to keep the vehicle motor running. This all translates to lower fuel economy.

Check your oil to make sure the engine is getting all it needs. Your owner's manual and service advisor at Allied Auto Works will tell you the proper weight and type of oil for your vehicle.

Responsible Car Care

Dirty oil grits up your engine, which also increases friction. So even if there's enough oil, you're still getting that extra drag that reduces your fuel economy. That's why your owner's manual recommends getting your oil changed regularly. It's good auto advice.

While you're checking your oil, you should take a quick look at your transmission fluid as well. Your transmission also needs clean, adequate fluid to work efficiently. An inefficient transmission also translates into lower fuel economy.

Your service advisor at Allied Auto Works will be able to check your oil and other fluids, top you off or change your oil if necessary.
Your owner's manual will have recommendations on how often you should check your oil and transmission fluid. But you can also consult with the pros at Allied Auto Works in Los Altos. The types of roads you drive on in CA, the climate where you live and the air quality in your area can all affect how often you should change your oil.

And don't forget that this will improve our environment here in Los Altos as well. Improved efficiency translates to fewer emissions. Changing your oil as scheduled doesn't just help your vehicle (and your pocketbook), it helps keep the air clean as well.

Well after all the dirty talk, I feel cleansed and I hope you don't have dirty oil in your car,

Cayenne

Duke's Fuel System Cleaning at Allied Auto Works in Los Altos for Better Performance

dukeHey it's Duke again and today I am going to bark to you all about cleaning your fuel system for better performance so let's get barkin!

A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.

Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.

The pressure in a fuel injection system varies depending on its type. Many gasoline engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.

Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It also adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle's engine.

Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel economy and loss of engine performance.

So it's important to keep your fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name CA fuel companies also deliver a more consistent quality of fuel than do bargain stations in the Los Altos area.

The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.

Check your owner's manual or ask the pros at Allied Auto Works in Los Altos to find out how often you should change your fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle, your filter will need to be changed more often.

You can also purchase cleaners that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won't be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use.

If your fuel injectors are gummed up, you can get a professional deep cleaning service at Allied Auto Works in Los Altos that will result in better fuel economy and improved vehicle performance.

Good vehicle care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.   Duke duke

Cayenne's Fuel Saving Tip for Los Altos: Check Engine Light

cayCayenne here today and here's a question for all my Los Altos neighbors :

 How long have you been enjoying the romantic glow of your check engine light?   Well that is what we will focus on today, let's get barkin'!


Hey, it's not there to create ambiance; it's a warning that something's wrong. (And, by the way, Homer Simpson's fix of covering it with tape is not a good idea.)

Many conditions that trigger the check engine light can hurt your vehicle. A lot.

If your date's eyes are smoldering in the soft glow of the check engine light, try to think of all the gas money you'll save by getting it fixed. Give Allied Auto Works a call when you areready and tell them Cayenne sent you! cay

Cayenne's Fuel Injector Cleaning at Allied Auto Works

cayHello Cayenne here and today we will do some cleaning, Fuel Injector Cleaning that is.  Let's get bark'in!   

 

 

In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected car driving down Los Altos roads.

Most fuel injectors for gas engines are known in the Los Altos automotive community as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

A few have recently introduced gas direct injection systems on some engines. They are now available at some CA dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

Although more complicated, direct injection technology promises greater power with improved fuel economy for gas-poor vehicles. CA motorists can expect to see more of it in the future.

High temperatures under your vehicle hood and variations in Los Altos gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

When injectors are dirty, the fuel doesn't burn as efficiently resulting in poor and loss of power. So it's for Los Altos residents keep their fuel injectors clean.

Your technician at Allied Auto Works can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Proper maintenance of your vehicle fuel system means that you will spend less on gas, enjoy strong performance and prevent repair bills down the road and you can thank your automotive dog blogger, Cayenne!

Cayenne's Good Service and Good Fuel Economy

 

Cayenne here and today I am going to let you on a little secret about Good Service and Good Fuel Economy.  Let's get barking!

cay

Most Los Altos auto owners want to save on gas and seek our advice on improving economy. At Allied Auto Works, we are frequently asked, however, if it is really worth the extra effort. Just how much money can Los Altos drivers actually save?

In today's Allied Auto Works article, we're focusing on the things you can do to improve your vehicle’s economy driving around CA. We'll tell you the potential savings per gallon of gas at three dollars and fifty cents, and we'll show a chart that also shows the savings at three and four dollars.

 

DOLLARS PER GALLON $3.00 / $3.50 / $4.00

TUNE UP 4%.12.14.16

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best mileage. A clean air filter means you get plenty of air. The fact that the air's clean protects your engine. That can save you up to ten percent or thirty-five cents a gallon.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

AIR FILTER 10%.30.35.40

Fixing a faulty oxygen sensor can improve economy by up to forty percent. That's a whopping dollar forty in savings per gallon. Bring your car to Allied Auto Works in Los Altos and we'll check your oxygen sensor.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

FAULTY O2 SENSOR 40%1.201.401.60


Chances are that if your oxygen sensor is kaput your check engine light will come on. Now, there's any number of things that could cause your check engine light to come on besides oxygen sensor problems. But if it's on, get it checked out as soon as you can at Allied Auto Works.

Here's an easy one for Los Altos auto owners. Inflate your tires to the recommended pressure. That could save you three percent or eleven cents a gallon. Even a little drop in pressure will bring down your economy, so check your tires every week.

 

DOLLARS PER GALLON$3.00 / $3.50 / $4.00

TIRE INFLATION 3%.09.11.12

Your vehicle has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced economy, or up to seven cents a gallon.

Another thing Los Altos vehicle owners can do to improve that costs nothing is to toss the junk out of our trunks. In other words, clean out the car and stop hauling around non-essentials. Don't treat your vehicle like a storage locker. Dumping one hundred pounds of extra weight adds up to a 2% savings at the pump.

So when you tell someone you were going somewhere anyway and they're welcome to come along, that's okay. But if someone tells you they need to come along and it's no harm to you since you were going anyway—well, now you can tell them, “Sorry, dude, but you're an extra fifteen cents a gallon!”

All joking aside, let's all do ourselves a favor and fatten up our wallets by practicing good car care and better driving habits in California and Allied Auto Works is here to help.
