{{newarticle}}

This is a common forum topic, so it will likely make a useful wiki article. Could potentially divide it up into sections corresponding to automotive systems and practices. 

For now, you can just add tips to the list below:

*Keep tires inflated to proper pressure.
*Keep up with regular maintenance ie. clean air filter, properly gaped and clean spark plugs
*proper alignment

*on a red light shift to neutral while it turns green
