My buddy sells aviation fuel and just gave me 2 barrels of jet A that was drained from a tank and can’t be sold for airplane use now. He has been running it in his 2000 Cummins for a few years now with no issues. He is mixing in standyne for some lubrication as jet A is pretty dry I guess. Just wondering if anyone has ran it in a 6.9 and if so any issues. It’s my bush truck so not a daily driver by any means.
