ATF is basically a 10W motor oil. Adding a quart of either this or MMO
to a tank of fuel has the same effects on the catalytic converter as
having an engine burn a quart of oil in the same time period. IT also
helps to destroy the O2 sensor. Would you add Diesel fuel to the gas?
The Techron is probably the best stuff out there for removing carbon
from the fuel injectors and intake valve area. Keep in mind that
excessive use of this will dilute the engine oil.

An excellent mechanic  told me that a quart of ATF(auto trans fluid) in
a full tank of gas will do the same as Marvel Mystery Oil with regards
to loosening carbon deposits and cleaning injectors. Has anyone tried
this or even heard of it?
