A few of the newer ats (atf+4 for dodge) is synthetic dusn't change color when you get it hot or old asper Dodge so imo avoid synthetic atf
as for 2 stroke synthetic. I won't run it in my 372xp chainsaw because of ash fawling and buld up.
old 2stroke didn't burn up= smoke and oil fawling
for a gasser more oil=less fule aka leaner to much oil can melt pistons

As for lack of testing what is the life expectancy for a injection pump 200,000 500,000 1,000, 000 mijust how many more miles duse atf give ? I have275000 on a vp44 using ctane booster 1floz for 3 gal skip it for 2 tanks and that old 12v starts talking clattering, hard starting
