OK then...seems pretty split between the "saw improvement" camp, and the "Snake oil" camp.
FWIW I tried some in my 88 4.0 a couple months ago when I flushed the system and installed a new 195* Mopar t-stat. Based on that limited experience, I have been undecided: been fighting a small air leak 'forever' that skews any results... plus after burping the #$@%^?! a couple dozen times, I have added a lot of non WW treated coolant mix.
Anyway the trail rig in question has never had 'serious' cooling issues, but I'll try it in that one since it never sees 'light' duty.
