What RPM should my car be in park?

For a passenger car engine, idle speed is customarily between 600 and 1000 rpm. For medium and heavy duty trucks, it is approximately 600 rpm. For many single-cylinder motorcycle engines, idle speed is set between 1200 and 1500 rpm. Two-cylinder motorcycle engines are often set around 1000 rpm.

Does revving your car waste gas?

Over revving your car is an easy way to waste fuel. As a general rule you want to change up a gear before reaching 2,500 revs. In a diesel car this figure is closer to 2,000 revs. Although the optimum revs for fuel economy can be even lower in certain cars.

Does high rpm clean engine?

This helps clean out carbon deposits that can foul the valves, throttle body, intake manifold, and the combustion chamber itself. … Prevent carbon gunk building up in your engine by letting it reach the redline every few hundred miles.
