What do the tech's here think of this stuff. Is it snake oil or is it really beneficial?
It's good stuff. GM first started using it in the "bug sprayer" in the late 1980's for cleaning fuel injectors. I add a bottle to the tank of each of vehicles about twice a year.
I'm skeptical of 99.9% of the "miracle cures in a can". Most are designed to separate you from your money.
There are only three that that I ever actually had confidence in. The bottles of Techron are one. It WILL clean injectors.
Another was GM's EOS, or Engine Oil Supplement. Not for regular use, but for a sticky lifter. Either a running "ticker" or a morning leakdown "ticker". This stuff would kick lifter varnish's ***!
And, the last was GM's Top Engine Cleaner. Not for regular use, just for carbon issues. Carbon, be gone! (in a massive cloud of noxious fumes and smoke!)
Thanks to the OP!
