I've never seen so much misinformation here before.ATF in fuel,not to use kero,MMO,and not to use any additive at all. WOW.First--ATF in fuel or fuel filters--It might have ''worked'' some in a 20 year old mechanical injectored old diesel because ''she smoked real good after I did it'' scenario probably happened.Probably also shortened the injectors life somewhat and maybe some other parts,but that's just conjecture.Second--#1 diesel is basically kerosene and that is what is blended [at least by me in the Northeast] with #2 diesel to call it [in part] ''Winter blend diesel''.I have a chart from Hess Oil that proves this with the percentages of each for the 4 months of Winter going by coldest ambient degree days.MMO? What is there to say except it's still a mystery why people dump it in a $40-50K or more truck or piece of excavating iron.Personally,40 years ago,I found Motor Honey worked the best in my '53 Studebaker to control the smoking.[funny face laughing]Lastly,let me answer that with this little tidbit---in the last week with our temps. a few times dropping to -15*,I ran across 2 guys who gelled up.Asked them WHY.Both said they didn't run any anti-gel in the tanks as they didn't expect such low temps.I run lubricity enhancer/anti-gel in every fill,year round.I can't remember honestly when the last time I gelled up---probably 30 years ago when I too got caught off guard.
