I will check my odometer today against mile markers on the highway, I guess that is the best way to do it??
The engine is origional, with 170,000 miles. She runs strong, minimal blowby.. so good performance bad mileage I don't get whats going on here
.
I don't know if the valves have been done but I doubt the PO did them at all, will do this weekend.
I'll check the brakes I know the rotors are still a little rusty so it could cause a little drag.
Will report back later tonight thanks for all the input so far!
