It's one of those "mystery fix-all" products
not much of a mystery, really.. just some mineral oil mixed with very harsh solvents and alcohol. - just like everything else..
It's a short term fix for carbon build up, but that's about it.
they make some interesting claims on the label of their motor treatment product:
1) injector, carb , carbon cleaner - this is what it does best, and is accomplished by the solvents.. the problem is, you can dislodge some big chunks and cause other problems. repeated use might affect seals and gaskets.
2) fuel stabilizer - I call this clever marketing.. the solvents break up any gummy residue from when fuel sits too long, but the fuel isn't being stabilized.. ( same with stabil )for that, you need metal deactivators, ( which you can't find in additives you buy at wally world )to keep the copper and vanadium ( metals in the fuel ) from falling out of suspension.. that's where the gummies come from..
3) frees lifters / rings - accomplished by the solvents breaking up the carbon.
4) de icer / anti gel - works just like the truck stop kerosene additives. all your doing is thinning out the fuel..this does wonders for octane & cetane.
5) upper cylinder lube - nope.. the alcohol in the product will strip out the lubricity from the fuel, and the carrier oil will just turn to carbon upon combustion anyway.
6) dries oil and fuel - ok, same principle as drygas.. adding alcohol to disperse water..and drying the fuel doesn't help with lubricity.
if you're just after a quick de - carboning, have at it, though.. just saying it's nothing special.
(she had a couple 15,000 mile dino oil change intervals on her; the Blazer, got a lot of nasty stuff out of the crankcase, improved idle quality and throttle response a good bit.
