Fuel Saving Tips

Best MPG is affected more by vehicle speed than engine speed.

In response to the tip that there is a "best MPG engine RPM of 2,000", engine speed in itself has very little to do with your real world MPG. The load placed upon the engine is much more important. Due to modern fuel injection systems, it's entirely possible for the same engine to burn the same amount of fuel at both 1,500 and 5,000 RPM, depending upon the load. An engine under 100% load at 1,200RPM will burn more fuel than the same engine cruising along at 20% load at 3,000 RPM. If you want optimal fuel economy, simply place as little load on the engine as you can regardless of it's size. Simple.
