To further reduce your consumption, do not wait until your car cool and group travel.
When you’re with your Family, on holidays in rural area, learn to manage car trips so that everyone does not repeat the same trip to the nearby town or the mall – it’s obvious. What is less is to not let the engine cool between several displacements. Your spouse has just returned with the car, it’s time to do the duty you had planned. Driving a cold engine can be 50% consumption higher than normal for the first three kilometres. Conversely, it is not necessary to let your engine warm up before driving.
