Took my truck on a 800 mile trip. Hauled some things back. Not heavy, but a load.
Observations, empty, me and my belongings in the truck. Running 65 MPH mostly, with some pretty good climbs in the mountains, 10.9 MPG.
Returning with load (empty part of this portion) mostly flat, a few small climbs, 11.3 MPG.
Sadly I was excited about these numbers as I expected worse.
I want to do a little tweaking with the timing and maybe go back to the original jets. I think it’s a little lean, may be time to invest in an AFR meter.
Edit: a little research and I see an AFR needs an O2 sensor hook up. And a pretty good chunk of change!
