GM made V6 blazers in the 80s. They were gutless and got almost the same fuel mileage at their V8 counter parts.
Only time they gave any benefit was unloaded on flat ground, where you wouldn't miss the power it should have and where the V6 is all you really needed.

Now if you had a turbodiesel 6.5L V8 and if it only got 20mpg then you would some kind of problem with the engine, or a fuel leak or 2 some where.
