Hey Folks,

Been looking though the archives and googling regarding fuel consumption of the 760 GLE with V6 NA engine. There isn't that much out there.

I've had the car for a month now and the PO told me it was a gas guzzler (he was using 15 to 20l per 100km!), but I dismissed that because he was VERY lead footed (practically lost his licence because of speeding).

The car runs well and powerfully and I have no problem getting it past 150Km/h but if I drive it at more conservative speeds (tested over 150km at approximately 100km/h), I barely get better than 13l/100. With the weight of the car and I would have expected that figure to get closer to 11. What do you think I am doing wrong, or what could be the cause of this thirst for gas? Or is it close to normal for this car? Any way to improve that?

The engine is two years old and running synthetic oil (5W50) and it feels very powerful. It doesn't seem to burn any oil. The oil is quite fresh, the air filter is almost new, the tires are inflated close to the upper limit and the AC was off when tested. I do get a noticeable gas vapour odour in the cabin when it sits for an extended amount of time (maybe corroded gas vapour venting pipe in the trunk?). Otherwise it idles correctly and performs extremely well warm or cold and it goes readily into overdrive (auto transmission). The catalytic converter was replaced two years ago and so was the O2 sensor. The AMM was replaced about three years ago. The engine starts instantly with no stumbing or hesitaion. The distributor, rotor, cap and spark plug wires were replaced last year. The fuel pumps are new from two months ago. There is no noticeable leak or gas smell coming from the car when I park it. It does seem to need some sort of alignment (it oversteers noticeably, especially when hitting bumps in the middle of cornering at high speed), the tires are quite worn and it seesm it would benefit from a valve adjustment (its first on that engine).

Any help would be gratefully accepted!
