Somebody told me that the fuel economy is worse with the Straight-4 than with the V6, ... giving the reason that the 4s had to fight harder to push the weight, ...

Does that hold water with anyone?


Nope. In general, engines give better fuel economy when they are under more load. There are many many examples where the "optional" V8 gets poorer mileage than the "standard" V6.

The other issue here is just that the mitsu 4 cyl in the old Monty's seems to be less efficient than tht V6. Probably due to the carburator.
