Nothing in your engine workers harder than your oil. With hundreds of moving parts, and thousands of explosions every minute, it's no wonder that engine oil needs to be changed frequently!
You've probably heard the old rule of thumb: Change your oil every 3,000 miles/ 5,000 kilometers or 3 months, whichever comes first. But some car manufacturers have introduced extended oil change intervals. They figure that a modern vehicle driven under the right conditions can go for 5,000 miles/8000 kilometers or more between an oil change.
The key phrase here is "under the right conditions". If you look at your owner's manual, you'll see two different maintenance schedules: one for "normal" driving conditions and one for "Severe Service". Severe service driving conditions include stop and go, short trips, towing, hauling, hot, cold, and dusty driving. That's why at AutoNetTV we often refer you to the severe service schedule in your owners' manual, because, for most of us Michigan car owners, that's the way we use our vehicles in everyday life.
Recently, four of the largest auto manufacturers in the world have extended engine warranty coverage for engine damage caused by oil sludge resulting from longer oil change intervals. They found that real-world conditions require more frequent oil changes than the 7,500mi/12,000 km interval they were recommending. They subsequently recommended more frequent oil change intervals and proof of timely oil changes in order to qualify for the extended warranty.
Oil sludge is the culprit. Sludge is oil that has turned to a thick, jelly-like consistency. Sludge can block passages in the engine, preventing oil from lubricating vital engine parts. Parts wear more quickly and may fail prematurely.
Sludge is caused by several factors. The first one is simply - time. The engine oil is contaminated by exhaust gas that eventually leads to sludge. That is where the recommendation to change your oil at least every three months comes from. Sludge can also come from oil that gets contaminated by water from normal condensation. A few minutes of driving at Michigan freeway speeds allows the oil to heat up enough for the water to evaporate. The problem is we often run errands or take other short trips that don't allow the engine to warm up enough for the water to evaporate. This is especially true in winter. Sludge also forms when the engine gets too hot, causing the oil to breakdown. Stop and go summer driving, towing and hauling are all prime conditions for creating harmful sludge. And every engine has hot spots that create sludge.
Given all of these factors, estimating when to change your oil is pretty complicated. A couple of manufacturers have computer programs built into their vehicles that record the number of cold starts, how many times the cylinders fire, engine temperature and other factors. From that, the computer estimates when you should change your oil and flashes a warning. But what if you do not have a vehicle with this feature? How do you know when to change your oil? We're not sure you really can. Which is why it is better to be safe than sorry. 3,000 mi/5,000 km or three months - whichever comes first - talk with a service advisor at Auto Surgeon Inc in Lansing and see if that's a good recommendation for the way you drive.
Fuel System Cleaning to Improve Performance in Lansing, Michigan
Posted February 9, 2012 12:00 PM
All modern vehicles come with fuel injection systems, so it’s a topic we all need to know something about. All new cars and trucks sold in Lansing, Michigan over the last 30 years or so have come with fuel injection systems.
The 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.
So how many fuel injectors does your car have? There’s one for each cylinder. So four, six or eight for most folks in Lansing, Michigan. 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 a pretty sophisticated part.
Auto Surgeon Inc can help you 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. The fuel needs to be sprayed in a particular pattern as determined by the engine design.
Over time, varnish can start to build up in the fuel injectors, effecting 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 wastes fuel.
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. Its real tempting to shop for bargains with fuel prices as high as they are, but major brands in the Lansing, Michigan area have better detergents and additives and deliver consistent quality.
What about a good fuel filter? The fuel filter is the next device in 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 we’re starting to see require 10 to 30 times as much pressure. And 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 Lansing, Michigan 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. But putting the cleaner in the fuel tank after you’ve had Auto Surgeon Inc 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 Domestic may be ready for a fuel injector cleaning.
