Asked by Will Harris
The fuel consumption on my 1999 VX Calais V8 continues to creep up and currently reads 17.1 L/100 km even though it has been well maintained. Any ideas why?
Answered by CarsGuide
9 Dec 2010You don't say by how much it has crept up and whether it's been a gradual increase or a sudden jump, but Holden's claim for town running was 15.0 L/100 km for a 1999 VT V8 and 13.5 L/100 km for a later VX V8. If it's running well and still packs a powerful punch you should look at those items that might affect the tuning of the engine. Replace the spark plugs, the plug leads, the air filter, perhaps clean the throttle body and give it a good run to blow out any carbon build-up.
