196 Fuel Economy Driving
Avoid High Engine Speeds
High engine speeds mean high fuel con-
sumption. Jerky driving also increases fuel
consumption when the vehicle is constantly
accelerated and slowed down. Avoid a
higher consumption by steady, even driving.
Refer to each engine manufacturer’s opera-
tor’s manual for information on the
engine’s optimum operating range.
Hill Driving Technique
Use the inertia of the vehicle to go over the
crest of a hill under reduced power. Use
gravity to help with acceleration when go-
ing down the hill. Build up speed before
reaching the next uphill.
High Speed
With increasing speed comes an increasing
wind resistance that negatively affects fuel
consumption.
