Cayenne's How to Know When to Change Your Oil at Allied Auto Works

cay  Good day, it is Cayenne and do you know when it is time to change your oil?  Today in the Duke and Cayenne's Corner, we're going to bark to  drivers about oil change intervals.  So let's get barkin'!

 

 It seems that as engine technology advances, oil change intervals become longer for Allied Auto Works customers. For example, recently four of the world's largest vehicle manufacturer's shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles (13,000 kilometers).

In real world Los Altos driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance: quite literally petroleum jelly – like Vaseline. This goop was clogging vehicle small engine passages so the oil wouldn't flow to some parts of the engine. This resulted in engine damage. We see it too often at Allied Auto Works in Los Altos.

The vehicle manufacturers began to offer an extended warranty to cover sludge damage. But there was a catch: the vehicle owner had to follow a new, lower service interval and provide proof of oil changes in order to make a warranty claim.

So here's the bottom line for Los Altos vehicle owners: with longer oil change intervals, it's essential to follow them closely. Back in the day of 3 months or 3,000 miles (5,000 kilometers), if you went an extra month or an extra thousand miles or couple of thousand kilometers, your oil was still fresh enough that it didn't have time to build up much sludge.

But if your recommended interval is 6,500 miles (10,000 kilometers) and you go over another thousand miles or couple of thousands of kilometers, you're getting into heavy sludge territory. You absolutely need to follow mileage intervals very closely. And don't forget your severe service schedule. If you do a lot of stop and go driving in CA, short trips, drive in dusty or polluted Los Altos conditions, hot or cold weather  or haul heavy loads, you're driving in severe service conditions. Your Allied Auto Works service advisor can help you determine which schedule to follow.

So check your vehicle owner's manual or talk with your Allied Auto Works service advisor about where and how you drive in Los Altos. Should you change your oil closer to the regular schedule, or the severe service schedule? You need to make the call.

Let me give you an example of this. Some newer vehicles have an oil change indicator. It has a sophisticated computer algorithm that tracks number of cold starts, engine temperature, RPMs, mileage and many more variables to come up with a recommendation for when to change the oil.

Depending on driving conditions, the indicator in one test vehicle came on at anywhere from 2,500 miles (4,000 km) to almost 7,000 miles (11,000 km). It's typically just over 4,000 miles (6,500 km). Sometimes our driving is easy on the vehicle – like a long road trip. Sometimes, our driving is hard on it – like towing a heavy trailer or a lot of around town driving. But, usually, it's a combination of both.

Once again, it's up to you to make the call as to when to change your oil at Allied Auto Works to protect your vehicle engine. Another place where CA drivers can go wrong is with the type of oil they use. More and more new cars are coming to Los Altos owners filled with synthetic oil. Without going into a lot of detail right now, let's just say that synthetic oil lasts longer and is very resistant to oil sludge.

But it also costs quite a bit more, so some people are tempted to use conventional oil for their oil changes. Now, it's always best to use the oil recommended by your vehicle manufacturer. Check your owner's manual see if a conventional oil alternative is allowed.

But getting back to the problem, if your vehicle came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil. If you use conventional oil, you can't use the synthetic interval. You need to shorten it.

Well you should have some slick knowledge about oil changes.........til next week this is 

CAYENNE! CAY

Duke's Keeping Your Engine Cool in Los Altos, CA

dukeHi Duke here and since the season is changing and things are warming up, I though we would bark about keeping your engine cool as those temps rise.  So as we always day let's get barkin'!

 



The cooling system keeps CA vehicle's engines from overheating while they are driving around Los Altos. Its job is to move heat away from the engine. Let's talk about the various components of the system and how they make this happen.

The radiator is the part most Los Altos drivers associate with the cooling system. Coolant flows through the radiator which has fine cooling fins that draw the heat out of the coolant and dissipate it into the air. To make sure there's enough airflow over the radiator, a fan pulls air over the cooling fins even when the vehicle is idling.

In some vehicles, the fan is powered by the serpentine belt. On others, an electric motor runs the fan. Electric fans turn on and off as needed. You may have heard the fan kick on shortly after you turn your vehicle off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.

A hose connects the radiator to the water pump. The water pump pushes the water into the vehicle engine block. Now the engine block and cylinder heads have passages for the coolant to pass through without getting into the oil or the combustion chamber. In the automotive community, these passages are referred to as the "water jacket."

While the coolant is passing through the water jacket, it absorbs heat from the vehicle engine on its way to the radiator for cooling. Between the engine and the radiator is a gatekeeper called the thermostat. The thermostat's job is to regulate the temperature of the engine just like your home thermostat regulates the temperature in your house. It gets your engine up to the correct operating temperature and then keeps it from overheating.

When you first start the engine, it's very cold and needs to warm up. So the thermostat blocks the flow of coolant to the radiator. As the engine warms up, the thermostat starts to let coolant flow through the system.

The final component the team at Allied Auto Works wants to point out is the overflow reservoir. This bottle is designed to hold some of the coolant. It'll have a mark that indicates whether or not you have enough coolant. This is where you should add coolant if you just need to top it off.

Caution: never open the reservoir or the radiator cap when the car's hot. The cooling system is pressurized, and opening those caps while it's hot can cause hot coolant and steam to escape resulting in serious burns.

Cooling system failure is the most common mechanical failure in vehicles around Los Altos, CA. At Allied Auto Works, we can do a periodic inspection of the components for  leaks, loose connections and weakening hoses.

Your vehicle manufacturer has also specified a cooling system service interval. With a cooling system service at Allied Auto Works in Los Altos, the old coolant is replaced with correct clean fluid that contains the additives required to prevent corrosion. The additives are depleted over time and you need fresh fluid for adequate protection. Your radiator pressure cap should be replaced at this service as well.

Well we should be cool now and you should know what to do as the weather ramps up in temperature this summer, til next time

With high fuel prices in Los Altos, CA, comes lots of gas saving advice. Some of it, like what you hear on  Auto is great.  When you get one of those e-mails that's going around telling you how to save gas, try to think it through.

Does it really make sense? Does it defy the laws of physics?

Do some research on the internet or ask your Los Altos, CA, service advisor at Allied Auto Works.

Duke's Fuel Saving Tip: Slow Down in the South Bay!

dukeWhoa, Roy Rogers says slow down and so does Duke here in the South Bay.    Hi The Duke here and today I will bark to you about slowing down when you drive and how it affects your fuel economy.........so let's get barkin'!

 

There’s not much Los Altos drivers can do about the price of gas in ?CA, but we can control - up to a point - how much we use. Our driving habits can dramatically affect our fuel economy.

The first thing we can do is watch the go-pedal. Hard acceleration just sucks the gas. Gently leave stop lights and plan lane changes so you don’t need to floor it. That can save you hundreds of dollars a year in improved gas mileage.

Go a little slower on CA expressways. Los Altos drivers who go more than 65 miles an hour (105 kilometers per hour) will see their gas mileage drop dramatically. Leave early so you don’t need to rush to be on time. And cruise control is your friend – steady speeds use less gas.

Plan errands ahead. Make fewer trips by combining errands around Los Altos.

Hey at current Los Altos gas prices, a lead-foot might as well be a gold foot.

Give Allied Auto Works a call and tell the The Duke sent ya!      duke
