there is no way he gets that kinda mileage at 70.
The gearing is too low.
The is a ling on here to a calculator that gives hp needed at certain speeds...given the specific vehicle(you input the info)
at 60 my car uses 30hp. at 70 it needs 50hp. it takes more gas to produce that extra hp.
If that explorer gets 30mpg at 70 then he should (and rightfully so) be proud of the 40mpg he could get at 55mph...........right!
I can tell you the mpg I get at 55, 60, 65, 70, 75.
Anybody who has been at this awhile (like the explorer owner) has a scangaugeII or equivelant item. And they have enough couriosity to see what the variuos limits are.
