Fuel Saving Tips
When driving it can be counter-productive to use cruise control. Yes, cruise control will keep you at an even speed, but it actually will lower your MPG's in specific cases. Sometimes using manual foot-gas is more productive than cruise. The prime scenario to abort from using cruise control are highway type roads with hills. The science behind the idea is that cruise control will rev up your RPM's to maintain speed on a hill. However, if you can coast with your momentum and lower your speed a couple MPH on the hill, you can achieve a pretty significant increase in MPG's.
