Every engine has a rpm range where it is most efficient. I don't know
what that range is on a B engine, and I don't know the rpm that 45mph
would correspond to. Especially if your test track involves some slopes,
no OD might be better, because I think I remember reading that higher
rpm/lower load on the engine gives better mpg (within reason of course).
