So I pulled up the carpet in the trunk, removed the cover from the trunk floor (took a bit of time to remove the fiberglass cover from the mastic that use used without chipping it . . . it was really in there). Connections looked well connected, no corrosion.

Took resistance reading while I was there (I will attempt to include a picture) . . resistance was 52.8 Ohms . . . 17 Gallon tank, with 42 miles on it . . given my 7 MPH average (testing, non-highway driving) that would mean ~11 Gallons or about 5/8 of a tank. Gauge read right below full. Drove car 21 more miles (3 gallons more). Gauge dropped to 5/8 full. Not very confidence inspiring as to accuracy.

If the answer is . . this is how it is . . . its a Smith gauge . . get use to it . . this is not your Audi . . . yada yada . .so be it . . I will stop chasing. Under normal driving conditions / highway and after a bit more tuning, I hope to see milage in the 12 MPG range . . . and will just keep a close eye on the trip gauge and get more familiar with the car so the gauge is more of a very rough guideline.

I appreciate the comments and guidance so far, and welcome any additional thoughts on the above.

Thanks!
