THE best I can get out of my 2004 VY CX 8 Adventra is 20 litres/100km, yet I read that new Statesman and Caprice V8 sedans are returning 14.7 litres/100km. Is this normal consumption for this car? Perhaps the motor is not fully run in, or is it simply the price you pay for V8 performance? Is there anything to improve consumption, short of converting to another fuel?
THE V8 Adventra was a bit of a dog in many respects, but 20 litres/100km is a bit too high. The Adventra is a heavy old nail so I would expect it to be pretty thirsty. I would think it should get 16-17 litres/100km on average. The only thing you can do is to make sure all is well with the engine and the electronics controlling it, make sure your tyres are inflated correctly and that wheel alignment is correct.
