[s-cars] S6 Fuel Mileage Addendum

[J. Khang]

OK, I'll chip in here. On single long-distance trips of 220 miles on the highway at 65 mph on the speedometer I usually get 34-35 mpIg so that's 28.3 - 29.1 mpUSg. This is done in an automatic S6, no mods and the reading comes from the fuel consumption meter. The fuel I use is 95 RON (about your 90 AKI) and I use AC because the outside air temperature is around 90-100F. At the very worst, I will get 32.5 mpIg or 27 mpUSg. The engine oil I use is 10W30 Guardol ECT (formerly QLT too) and the fuel consumption is even better if the trip is done shortly after an oil change. The car has a sticker in the boot (and in the paperwork) that says it left the factory weighing 1420 kg, which is some 200kg short of what it is supposed to be. What do your cars' stickers say?
