For those unfamiliar:

I use the Lie-O-Meter, the overhead factory readout for average mph. Just divide the miles of each tank by the Elapsed Time using a 100-minute clock (where 15" = 25; 30" = 50 , etc). 15:13 e/t = 15:25 iow. 323-miles divided by 15.15 = 21 mph (which would be a slow, sorry average mph for FE). Re-set per fill-up.

The tire change would be worth 1-2 genuine mpg at some point. The PIRELLI Scorpion ATR, an on/off road traction tire is well-rated in the TireRack survey, I wouldn't change it either (though I didn't look to see what other CTD drivers are saying about it where the owner mileage is above 20k). The LRR MICHELIN LTX A/S is a highway rib tire with about zip for offroad traction, but wear like iron. I may get 250k out of the first two sets. Were I to move to snow country I believe I would keep them, but have a dedicated snow tire (as a retired engineer in Edmonton, Alberta uses on his 2WD Canadian hotshotter, the NOKIAN Hakkepeliita LT as his dedicated winter tire. His average -- on a 300k 2007 truck -- is above 22 US mpg.)

I may have to do the "tank mod" (as it is called) to get another 3-gls capacity. Then maybe someday I'd be crazy enough to drive a roundtrip to/from Balmorrhea State Park at a low speed to see if I could net 1k from one tank . . would only have to break 27 that way (that I've done before).

Sure would irritate the hotrodders that "a few of us" can run 1,000-miles on a basically stock truck. Some of 'em are lucky to see 400-miles to a tank, ha!
