Air…….it is everywhere. Used for just about everything. Most importantly breathing. Like all living creatures the engines in our vehicles need air to breathe. Human and mechanical filtering systems serve the same purpose they keep dirt, dust and contaminates out. It can take as much as 10,000 gallons of air for every gallon of fuel an engine uses to operate. Humans have “natural” filters. The engines in our vehicles use artificial filters. A vehicles air filter working properly can improve power, economy and performance up to 10 percent. That is why checking and replacing a dirty air filter is important. A good basic rule would be to replace an air filter every 15,000 to 20,000 miles during average conditions. Average conditions means clean roads and moderate temperatures. In Las Vegas the roads along with dusty conditions require more frequent air filter replacement. The air filter should be checked with every oil change. Happy Motoring and Be Safe.
