Those ingredients sound like chemicals to me, but who gives a flying flip whether or not it is technically a “chemical”? What I care about is DOES IT WORK? Will it clean the carbon and gunk out of my engine and make it run right? Is it safe to use on a fuel injected 2000 Olds Intrigue 3.5 V6? How about a fuel injected 1998 Chevy Malibu 3.1 V6? Can I really add 1.5 oz per gallon directly to my oil fill cap? How about sucking some through a vacuum hose (such as PCV) as I have heard done? Will it foul my plugs (they need to be replaced anyway, so if so I will do it before I replace them)? Will I need to change the oil soon afterward? Will it clean my ERG? I don’t need some official ‘Seafoam Approved’ instruction sheet, just plain English please!
