That is how I understand it![/QUOTE]
Correct ~~ at least for the Ford 6.7. Not sure how it works for older trucks. Like ethanol ~~ mileage drops a little and it costs as much or more. No stations have it near my home except Wal-Mart (Murphy) which makes it easy to avoid. One Pilot truck stop had it in GA, I pulled out as a stop a few miles away did not and fuel was 30 cents less.
