Ill stick with seafoam.. Much cheaper and ive notice results with seafoam..

Well you only put it in the oil with each oil change, so that's once every couple of months (with normal driving). I'm not saying this stuff works, who knows. They definitely tell a good story, and putting some in your oil will clean your valves, rings, etc and help give you a better burn. Like others stated, just not sure how safe it is. We used to pour marvel mystery oil in the carb and crankcase of older vehicles for the same reasons. It definitely cleaned them up and stopped the smoking and knocking. But we never used it continuously.

That said, MMO is now recommending a qt of MMO with each oil change (about $4) and 4 oz with every 10 gallons of gas (about $0.50) and they claim the same benefits as ethos.
