I haven't posted the final numbers yet, just filled up last night.

I will say that filling this tank to the top is a real PITA. Each time was about 15 minutes messing with the foam and waiting for it to gurgle down. It also does weird things to the fuel level indicator. When I first started out after filling up, the gauge read full then quickly started dropping. It looked like I was hemorrhaging fuel from somewhere because the gauge was literally moving before my eyes. It dropped down to about 3/4 then slowly rose back up and then fell again.

I ended up stopping to make sure there was no leaks from anywhere. All was good so I went on with the drive. My observation was that you can cram about another 2 gallons in there after the first click stop but it takes forever. Also, the MPG figures were in line with my previous readings where I simply let it click off and then continued until it clicked off again after a short pause.

When I get home this evening, I'll do a screen shot of my spread sheet with my stops and average speed calculations along with the gallons used and mileage, etc...
