Flameouts Are No Fun
There is this stuff called “diesel exhaust fluid”. It’s not supposed to be used as a fuel additive. Diesel engines don’t like that.
But Murphy being the bastard that he is, DEF has been added into fuel stocks. it is really bad when it is added to Jet-A, which is essentially diesel fuel that is made to a higher purity level.
DEF has been found in Jet-A. What seems to be happening is that instead of adding anti-icing additive to Jet-A, the guys at the fuel farms at airports have added DEF.
