Fuel Saving Tips

Partialy Block Off Your Radiator Grill.

This especially applies to diesel vehicles. The sooner your engine gets up to temperature the more efficient it will be. For example my (diesel) car gets almost half the MPGs it would get when up to temperature. I have blocked off the lower grill (with black duct tape) which allows my car to warm up faster and keep a sturdy temperature. This also improves aerodynamics of your vehicle (if done correctly). I am doing this in about 6-15 Celsius weather and see a decent increase in MPG and I can also use my heaters earlier. IMPORTANT Be sure not to block off your intercooler (if fitted) as this helps MPG and keeps intake air temps low and intake air density higher. It is extremely unlikely your vehicle will overheat but for the first few journeys keep an eye on your coolant temp.
