Cayenne's Fuel System Cleaning at Allied Auto Works

cay

Is your vehicle sometimes hard to start early in the morning? Hi Cayenne here and when you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your vehicle's fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy.

Most Los Altos vehicles have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system.

Some Los Altos residents are interested in buying fuel system cleaners that they can pour into their gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning. For that, you need to see Allied Auto Works. Allied Auto Works has the professional tools and chemicals to really do a complete service.

Allied Auto Works uses a process that gives your vehicle a deep, professional fuel system cleaning. You need to remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. After a professional fuel system cleaning, you'll notice more power, better fuel economy and reduced exhaust emissions.

The cleaners also help prevent rust and corrosion in your fuel system and lubricate engine parts.

Fuel system cleaning is just one of those recommended service items that help keep your vehicle running strong. As with all maintenance, it can help avoid repairs that often result from not taking the right preventive steps. Los Altos residents will notice the difference in how well their vehicle runs. Check with your friendly and knowledgeable pros at Allied Auto Works to see when your vehicle is scheduled for a fuel system cleaning.

An ounce of prevention really is worth a pound of cure for Los Altos vehicles.

Duke's Fuel Saving Tip: Los Altos Tune Up

duke

Duke here. Have you ever gone to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That's why they tune up together. Now this is no surprise; I'm going to relate the orchestra to your vehicle. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.

We call this... (ta-da) a tune-up. When an orchestra is out of tune, you get a bad concert. When your vehicle is out of tune, you get bad performance and bad fuel economy.

So check your owner's manual for recommended tune-up intervals. Or ask your Los Altos service advisor at Allied Auto Works what he thinks.

...Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.

Cayenne's Don't Be Fuelish

cay

Cayenne here, and today we are going to bark about fuel. If you smell gasoline in your vehicle, pay attention to your nose, like I do, because the nose knows.  That's because it has an important message for you.  So don't be FUELISH and let's get our scent on the trail.

Newer vehicles should never have a gasoline smell inside. One of the most dangerous conditions can come when your fuel line system has a leak or multiple leaks. Vehicles with fuel injectors are under pressure, meaning a crack or small hole in a fuel line can allow vaporized fuel to escape, sometimes around hot engine parts. Gasoline vapor and hot metal? You see the problem.

One of the most common causes of a gasoline smell inside a vehicle is a fuel tank leak. The gas tank can rot or be punctured by road debris. An Allied Auto Works technician can evaluate the condition of your fuel tank and suggest either repair or replacement.

Fuel injectors can develop small leaks around their seals or O-rings. Those can deteriorate over time as the material they are made of gets old and less flexible. A technician can replace those parts.

Modern vehicles contain something called a charcoal canister. It gathers evaporating gasoline vapors from inside your fuel tank and prevents them from venting out to the atmosphere. If that canister has a leak, you'll smell it. One hint that you have a problem is the Check Engine light may come on.

You may have a leak in your fuel tank vent hose. Or you may be smelling gasoline simply because your gas cap is loose, the cap is faulty or—yes this does happen—your gas cap is missing altogether.

Consider the dangers of gasoline fumes seriously. Inhaling them can be bad for your health or they may start a fire. Don't fool with fuel; have gasoline odors checked out right away.

Here is my quote for this week,

You can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time. 

~Abraham Lincoln

Cayenne's Clean Fuel ? Clean Performance for Los Altos Drivers

cay

Cayenne here and today we are going to bark about how to keep your fuel clean in your vehicle which in turn gives a clean performance for your car. So let's get barkin' on clean fuel and what you need to do. 

Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the vehicle engine. Los Altos auto owners don't need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.

Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.

The harder your fuel filter works, the more often it needs to be replaced. Check with your owner's manual to find out how often it should be serviced and how long you can expect it to last. Los Altos drivers should change it before it becomes clogged. Your friendly and knowledgeable Allied Auto Works service advisor can help you with recommended fuel filter replacement schedules.

Good vehicle care means following recommended schedules for preventive maintenance, including changing your fuel filters. Take the auto advice offered in every owner's manual and have your vehicle regularly inspected at Allied Auto Works. It may save Los Altos auto owners money by preventing costly repairs, but it will also repay them in improved safety and peace of mind.

I leave you with my motivational quote for this week,

Cayenne's Guide to Saving Fuel: Car Weight

cay

Happy New Year 2024!  Cayenne here and I welcome you into the new year.  I don't know if you have noticed, but gas prices have been coming down here in Ca but we know they will probably creep up again for us Californians.  The team at Allied Auto Works in Los Altos, and CA car owners are all talking right now. Better gas mileage. Fewer emissions. Los Altos drivers want to save the environment and their pocketbooks.  

And we all know—or should know—that preventive maintenance will help maximize fuel economy. But is there something more people in Los Altos can do? After all, some of us folks can't cut back on our driving, and others would like to do more to economize.

Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get from point A to point B. And that means buying more gas in Los Altos and producing more emissions.

Of course, your vehicle's weight isn't negotiable. And you can't do much about the weight of your passengers. And this isn't an article about diet and exercise.

But look around your vehicle. Are you hauling a bunch of unnecessary weight around? Do you really need your golf clubs every time you leave your home? Store sports equipment in the garage. Load it when you need it and store it when you don't. Who knows? The extra exercise just might reduce the other type of weight in your vehicle.

The same goes for anything else in your car: make-up kits, music collections, extra electronics, spare clothing; whatever your particular extras may be. Pack it when you need it; store it when you don't.

Clean out your trunk. You'd be surprised how much weight you're lugging around in plain old junk. Toss old papers, leftover food and regular old dirt. Even if it's not a lot of weight, you'll feel better when you get into your car. A good cleaning is also part of good car care.

Now, don't toss stuff you really do need. You do need that spare tire—the one in your trunk. And a kit of emergency essentials is not a bad idea. But just carry around the day-to-day essentials. You can pack a more extensive kit and store it in your garage, then toss it in your vehicle when you go on a longer trip, but you don't have to lug it around all the time. After all, are you a driver? Or are you a junk chauffeur?

Lose the junk and save some money in Los Altos.

Duke's Fuel Injection Basics for Los Altos

duke

Duke here, and today I will inject you with fuel injection basics for your vehicle.  All modern Los Altos vehicles come with fuel injection systems, so it's a topic Los Altos drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.  Let's get barkin' more on this subject!

So, how many fuel injectors does your vehicle have? There's one for each cylinder. So four, six, or eight for most folks in Los Altos, CA. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are pretty high-tech.

Allied Auto Works can help Los Altos drivers with a fuel injector cleaning service. What's the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It's important that the fuel is sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, affecting the pressure, pattern, and timing of the fuel charge. The result is that the fuel doesn't get burned as efficiently as it could. That robs performance and hurts fuel economy.

What about dirty fuel? How does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high-quality fuel. It's tempting to shop for bargains in Los Altos with fuel prices as high as they are, but major brands in the Los Altos, CA, area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is a component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it's clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It's important to replace the fuel filter when your manufacturer recommends it. That's part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines for Los Altos drivers are starting to require 10 to 30 times as much pressure. Some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There's no room for dirt and gum in a precision part like that.

There are a lot of good products available in Los Altos, CA, that can clean fuel injectors. They're best used to prevent fouling in the fuel injectors. Many can't clean a seriously gummed-up injector – that requires a professional deep cleaning, like those we offer at Allied Auto Works in Los Altos. But putting the cleaner in the fuel tank after you've had Allied Auto Works take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your vehicle may be ready for a fuel injector cleaning.

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

duke

Hey Duke here and did you 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.  So today we are going inject you with knowledge of fuel injection and let's get barkin'!

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 Gives Your Engine Clean Fuel with a New Fuel Filter from Allied Auto Works

duke

Duke here, and your vehicle requires plenty of clean fuel to run.  Today we will bark about keeping your vehicle's fuel clean.  So let's filter threw and get barkin" about clean fuel with a new fuel filter!

If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your vehicle engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts performance as you drive around the Los Altos area. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.

That's why all vehicles, including vehicles, come equipped with a fuel filter. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at Allied Auto Works in Los Altos.

If your fuel filter is clogged, the vehicle engine can't get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your vehicle engine running but doesn't protect it from contaminated fuel.

Los Altos drivers may find that they need to change their fuel filter at Allied Auto Works more frequently as their vehicle ages. Over the years, additional sediment and rust accumulate in the fuel tank and can be drawn into the fuel system.Your fuel filter stands guard at the gates to your engine to protect parts and maintain performance.  So make sure your filter is doing its job and book an appointment today!

Duke's Fuel Filter Service in Los Altos, CA

duke

Good day, Duke here and today we are going to filter through a very important part; the Fuel Filter.  There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn't seem right.



Fortunately, a lot of those things can be taken care of in routine maintenance. They may not be easy to remember because it is a long list, but your service center at Allied Auto Works can help you know what's scheduled to be taken care of.

Some of us in Los Altos, CA, really don't look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.

But automotive maintenance is all about prevention and addressing small problems before they get big. Let's take the fuel filter, for example.

You may not know this but the median age for private vehicles on our Los Altos, CA, roads is over nine years. When vehicles get older, five years or so, they've accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine, it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation is the lowly fuel filter: a very inexpensive part that doesn't cost too much to replace. And your vehicle will just run better too.

A clogged fuel filter can't let enough fuel through. You might notice at first that your vehicle is running fine around town but struggles or sputters on the Los Altos, CA, freeway or when you accelerate. Enough fuel can't get through to meet the demands of higher speed. If it gets bad enough, your engine might just shut off or not start at all, which could be dangerous.

Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element, so dirt ends up in the engine. We've already talked about how expensive that can be.

The fuel filter is even very important for newer vehicles. The fuel is still dirty even if there isn't rust in the tank. It's just that the fuel filter will need to be changed more frequently as the vehicle gets older.

How often should you change your fuel filter? Check your owner's manual. Your Los Altos, CA, service advisor at Allied Auto Works can tell you as well. It's usually around 30,000 miles (50,000 kilometers) or so. Ask if it's time for a full fuel system cleaning as well. They often go hand in hand.

It's good to know that your Los Altos, CA, service center has your back. When you're motivated to maintain your vehicle's performance and to reduce operating costs, you'll think of Allied Auto Works as your ally - and maybe even your memory.

Duke Keeps It Flowing with a Fuel Filter Replacement at Allied Auto Works

duke

Duke here and today we are going to filter out the mystery of what a fuel filter actually does in your vehicle.  So let's get the fuel flowing and filter through it. 



The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around Los Altos use fuel filters.

Generally speaking there's not a lot of dirt in our Los Altos area auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That's because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your vehicle is five years or older, it can actually have a fair amount of sediment built up.

That just means that the fuel filter has to work harder as your vehicle ages. It'll get clogged sooner and need to be replaced more often.

A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That's because enough fuel is getting through around town, but when you need more fuel for speed, enough just can't get through the filter. Obviously, that could be dangerous if your car or truck can't get enough power to get you out of harm's way.

For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.

This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don't want to cause them damage just because you didn't spend a few bucks to replace a fuel filter.

You know, in a way, the fuel filter can be the poster child for preventive maintenance. It's a little part, it's simple and it's cheap to take care of. But if it's neglected, it could lead to thousands of dollars in repair bills.

Those auto service schedules in your owner's manual are there for a reason. If ever you don't understand a recommended service, just ask your Los Altos service advisor at Allied Auto Works. We'll be happy to explain.

For more information about your fuel filter, visit Allied Auto Works at 2073 Grant Road in Los Altos, CA 94024.
