I've only been averaging 29 on this tank according to the computer. Lot of city driving though...And some spirited driving. I've been meaning to figure gas mileage at a fill up but I don't remember to write down the mileage since there's no tripometer (that I can tell).
69.5 mpg is unreal...I don't think I will ever see these numbers with my driving habits.
The most I think I've ever seen is 55 mpg under ideal driving conditions that includes 70 degree outside temperature and predominantly highway driving at 55-60 mph.
As I mentioned in my other post, the gas mileage drops significantly when the outside temperature is below freezing. Like 5-10 mpg lower than the average. I'm still averaging 42 mpg overall and I'm quite happy with that.
