Fuel computers ain't worth the money - I my opinion they are at best only an estimate - with an accuracy of approx plus or minus 10%. In all honesty they're about estimating and without accurate measuring devices how can they calculate the amount of fuel used. They just seem to another bell or whistle added on to impress the buyer. In all honesty the only accurate method of measuring fuel consumption would be to use a specialised flow meter and I have'nt heard of one yet being fitted to a car produced for the public. In all honesty I wouldn't rely on them. Fuel consumption needs to be measured over a broad range of circumstances as there are just too many variables such as driving style, weather, road conditons, traffic, type of road surface, tyre pressure, etc., (the list goes on) to take into consideration. The best way is to fill her up to the throat on each fill and then calculate the average over about 3 tank loads. Also I'm of the opinion that the computers are set up to give the best results as otherwise it would affect sales. Think about it.
