I was hoping for at least 20 MPG. But, close enough. Maybe had I had 3.54 gearing. Oh well.

At least it's better than the 9 MPG I was getting with the old 360.
I have gotten 22.1 IIRC as my best tank on my '89 RC with a 12V Getrag 4x4 set up with 3.54 gears in the D60 + D70s

I would guess the gearing is hurting you the most.

Ya, that's what I was thinking. Close enough though. I'm not complaining.
