Over the last few fill ups: 21.0; 20.0; 22.3; 21.6; 19.3; 20.9; 20.4.
Includes a lot of driving around the mountains in Arizona (between 4k-9k ft) and then driving back to DFW. No real babying. 75 on the highway including a fierce headwind on the 20.0 tank.
Installation took me 15 minutes max. And if I knew what I was doing, I probably could have had it done in 5. Harness is already there. Hardest part was just being comfortable with pulling the old panel out.
If you play around with filters on the allocations spreadsheet, there seem to be quite a few that are moving through the system. You just might have to travel a bit to get one.
