Just as our bodies need clean air to function properly, your sedan engine needs clean air to operate efficiently. Let’s go egghead for a minute. For every gallon of gas we burn driving on Iowa expressways, twenty pounds of carbon dioxide comes out the tailpipe. Question: how can a gallon of gas that weighs a little over six pounds produce twenty 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 twelve thousand gallons of air to burn a gallon of gas in your engine. Clearly, your sedan needs a lot of air to keep going in Ankeny. 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 sedan also works better when its internals are clean. When your sedan air filter’s 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 sedan engine does you no good.
So, we’re talking potential damage for Des Moines drivers. But another big thing is wasted fuel. Your sedan engine management computer tries to mix the correct amount of air in with the fuel. If the filter’s clogged, there isn’t enough air for the optimal fuel to air mix and that really messes with gas mileage.
In fact, replacing a dirty air filter at All Pro Servicenter can improve your fuel economy by up to ten percent. At today’s Ankeny fuel prices, you should be able to pay for a new air filter before your next oil change.
The verdict: When your sedan 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 Iowa. A simple visual inspection at All Pro Servicenter will tell you when you need a new engine air filter.
