My car is a manual 5 speed. normally i drive 50mph in 5th gear and keep the rpm at 1500. But im affraid im lugging it. whats a good rpm to keep at to save gas?
Its not so much a good RPM to save gas, but rather your driving habits. Variations in speed and constant stop and go burns gas quicker (the reason auto manufacturers give you HWY MPG and City MPG). A way to save gas is to have good driving methods and ensure you keep your vehicle maintenance up,i.e. tune up, oil change, Tires and tire pressure. :worshipAMEN! people do not relise how much bad driving effects milage.
There is no such things as an economy tune:forgot to put in last post but also, get an economy tune. thatll help!
