Fuel Saving Tips
Steeper uphill coming up, it may be in your best interest to just scramble up it as fast as you legally can - because in addition to the usual rolling resistance and air resistance, going uphill means you are also encountering a constant gravity resistance - which drags you down at the same rate for a given grade regardless of what speed you're at. Of course, take care not to overstress the engine, and if you're going a very high speed the increased aerodynamic drag might exceed any fuel savings on avoiding gravitational drag.
