Petrol increased by 22.6% in the past year and filling up is painful! Fuel-wise tips like driving slower, using less aircon, and maintaining  uniform speed with reduced acceleration and braking are well known but consider the following…According to wind-tunnel tests, a canopy or bakkie load-bay cover can reduce drag by over 5%, reducing fuel consumption by 1 to 2%. Roof racks also increase the drag factor significantly, so attach one only when needed. Similarly, the larger the frontal area of the vehicle, the higher the wind resistance and the more fuel is consumed. Don’t use a bullbar unless you really need one.
