So I've been trying to figure out Aces' MPGs. Grimace never did better than 14 MPGs, and that was only when I babied the hell out of it. I also need to figure this out because my fuel gauge isn't working correctly (I ran out of gas at my co-worker's shop during the u-joint fiasco).
So even with this monstrosity under the hood:
I managed to pull 20.2 MPG out of Aces. That's a mix of city/highway (normally 65mph+) I'm pretty pleased with it.
