Old timers have been adding Marvel to their fuel for ever. I doubt it does much good in today's engines.Oh you want to add a oil supplement to the fuel. Enjoy. I have no freaking idea.
I use it as an oil flush after starting an old bike for the first time.. 25% MMO in the sump, idle (or slightly above) until warm, dump the oil, filter, and screens.I remember my Grandad's old Ford fishin' wagon was sludged up from using Pennzoil (used to be Fords and Penz. didn't go together for some reason). My brother put two bottles of Marvel in it and filled it up with Quaker State and it broke all the sludge free, plugged up the oil pump screen and seized the engine. So it must have some anti-sludging abilities when used in the crankcase. But oils have come so far since then, I don't see any need for it.
FYI, since I was 14 or so when it happened, I didn't do any research on the subject.![]()
Claimed benefits
Marketing literature makes claims about lubricating qualities, cleaning and friction reduction capabilities. However, little robust evidence exists documenting these purported benefits. The product has previously been marketed for use in all kinds of engines, including aircraft engines. However, it has been implicated in one aircraft crash where an engine suffered catastrophic damage during take-off after Mystery Oil had been used as a fuel additive. The engine damage found was attributed to detonation, which would be consistent with the octane reducing effects of Mystery oil.
The name Mystery Oil comes from Burt's answer to the question, "what kind of oil is this?" to which Pierce would respond, "It's a mystery!"
Composition
The product is composed of 74 percent mineral oil, 25 percent stoddard solvent, and 1 percent lard.
Dichlorobenzene (1,2-Dichlorobenzene (ortho-dichlorobenzene))0 – 5% , Fine White Mineral Oil 70 – 100% , Mineral Spirits 20 – 30%
Well, there ya go... an additive that works! Just has to be put in the operator rather than the machine. :biggrin:If I eat a double cheeseburger and then put ear plugs in before I ride, I notice my engine runs much smoother--I don't know about the bike but MY engine runs much smoother:biggrin:

Best Answer .. I do use Seafoam Now and Then and not really sure it truly helps anything .. But it doesn't hurt anything for sure either ..A capfull in your tank wont' hurt anything.
Not saying it is going to help anything...
