L and M Motors Inc: Why Replace Your Engine Air Filter?

Posted June 29, 2012 12:00 PM

Just as our bodies need clean air to function properly, your vehicle engine needs clean air to operate efficiently. Let's go egghead for a minute. For every gallon of gas we burn driving on Anchorage streets, 20 pounds of carbon dioxide comes out the tailpipe. Question: how can a gallon of gas that weighs a little over six pounds produce 20 pounds of carbon dioxide?

The answer is that the carbon comes from the gasoline, but the oxygen comes from the air. You see, it takes about 12,000 gallons of air to burn a gallon of gas in your engine. Clearly, your vehicle needs a lot of air to keep going in Anchorage. A lot of clean air is best.

You've seen the pictures of people in Japan wearing face masks. They want some kind of filter to keep unwanted pollution and germs out of their lungs. Well, your vehicle also works better when its internals are clean. When your vehicle air filter is dirty, it simply can't trap any more dirt, so the pollutants just pass through into your air intake system. From there it can clog your fuel injectors and even get into the motor itself. Not surprisingly, burning dust and pollen in your vehicle engine does you no good.

Replacing a dirty air filter at L and M Motors Inc in Anchorage can improve your fuel economy by up to 10 percent. At today's Anchorage fuel prices, you should be able to pay for a new air filter before your next oil change.

The verdict: When your vehicle engine air filter needs to be replaced; it needs to be replaced. How often depends entirely on the level of air pollution where you drive in AK. A simple visual inspection at L and M Motors Inc in Anchorage will tell you when you need a new engine air filter.

Anchorage Drivers: Is It Time to Replace Your PCV Valve?

Posted June 14, 2012 12:00 PM

The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine.


When you are diving around Anchorage, fuel is burned in your vehicle engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.

Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to sludge. Sludge is like Vaseline and clogs passages in the engine, leading to damage.

Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in Anchorage, AK.

Enter the PCV valve. It's a small, one-way valve that lets out the gases from the crankcase and routes them back into the air intake system where they are re-burned in the engine. Fresh air comes into the crankcase through a breather tube. This makes for good circulation in the crankcase. And that gets the air out. As you can imagine, however, the valve gets gummed up over time.

Your vehicle manufacturer usually recommends they be changed somewhere between 20,000 to 50,000 miles/30,000 to 80,000 kilometers. Unfortunately, PCV valve replacement is left out of some vehicle owner's manuals, but your friendly service advisor at L and M Motors Inc, we will make sure your PVC is replaced if needed.

Busted: The Maintenance-Free Myth in Anchorage

Posted June 7, 2012 12:00 PM

There's a segment of the Anchorage area population that's not committed to proper vehicle maintenance.

Now, the ignition system in your vehicle is electronic and controlled by the engine management computer. Spark plugs rarely get fouled and will last for as much as 100,000 miles (160,000 kilometers). So tune-ups used to force you in to L and M Motors Inc for service, and while you were there you just took care of whatever else was on the list.

Also, in recent years, a large percentage of new vehicles in Anchorage have been leased. These folks plan on turning the vehicle in after two or three years, so they haven't focused on the maintenance that helps a vehicle last longer.

Given all that, what's the benefit to keeping up with factory scheduled maintenance? Well, your vehicle will perform better and return better fuel economy.

Those benefits pay for themselves as they go along. The big plus is that major repairs are prevented. And these aren't just repairs that are a long way off. Modern vehicle engines are far more sophisticated and have many parts that are in critical need of proper lubrication. Missing just one oil change can allow oil sludge to start forming. Sludge clogs small engine passages, robbing parts of the lubrication they need. An expensive failure could easily occur within two or three years.

And modern engines require more sophisticated fluids. Because of the different types of materials that are used to make auto parts, things like aluminum, plastics and steel, different types of additives are required to protect automotive components from corrosion. These additives deplete with time as well as with use.

Taking care of the little things now prevents big problems later. At L and M Motors Inc, we have been taking care of all those little things for years. Your vehicle still needs to be taken care of – it's just that some of those points of care have changed with automotive advancements. The need for proper maintenance in Anchorage drivers vehicles did not go away.
