Re: Pleasantly surprized 3.6L mileage
Suspect is more into it than just the 3.6. For example mine is RWD and at 4420 lbs is probably the lightest of the WK2s, have seen specs over 5,000 lbs. Where I live is pretty flat, steepest grades are at overpasses.
Also my driving is about 10% 25 mph neighborhood, 20% 35 mph, 40 % 45 mph with stoplights, rest urban Interstate (sometimes clogged, others not).
Consequently, over 20 mpg on the second tank of winter blend seems pretty good, my 3.8 V6, 3600 lb cars have been running about 18.
