Hi guys,
Recently I noticed my stock 3.8 auto had been absolutely guzzling the fuel. I checked the trip computer, and it was giving an average consumption of 21l/100km which is ridiculous, considering I never rev it over 3000rpm. After a couple days of grandpa driving, it went down to 19l/100km - still not good enough. Anyway today I checked my tyre pressures and they were all sitting on about 28psi except for the back left which for some reason was only 16psi, which is probably pretty dangerous. Anyhow, I topped them all up to about 33psi.
Is it possible for bad tyre pressure alone to get these sorts of fuel consumption figures? Or is something else at fault (O2 sensors, air filter)? The car's just been serviced by the way, so it's all a bit strange.
Cheers
