What is the FE sweet spot for...
does anyone know the FE sweet spot(hwy) for GM 3.8 v6(fwd) cars? my 95 olds apparently is not scan gauge compatible. will be testing my wife's car(same motor) for this soon, but since she drives very little hwy and her car is rwd, there prolly is no info benefit in it(at least for my car).
keep in mind that i'm NOT willing to drive 55mph on the 70mph FL turnpike. just want to know if 75 is more efficient than 70 or if 65 is MUCH more efficient than 70,etc.
any help would be appreciated! rh77 and anyone else that has owned/owns or rented one of these vehicles thanks in advance for your info.
