My Car s Running Fine. Improper tire inflation wears tires faster and wastes fuel because the engine has to labor harder to move the vehicle. Improper tire alignment can wear out your tires more quickly. The more timely vehicle servicing you do, the more money you save in the long run. The longer you wait until you service, the harder your car has to work.
Cars suffer carbon build up, dirty fuel injectors, and dirty throttle bodies.
City driving is especially hard on cars. Fuel filters get plugged causing the pump to labor harder. This creates a domino effect on everything from the spark plugs to the transmission. Waiting doesn't make sense. Each manufacturer has compiled a list of recommended service intervals.
