I have been using Seafoam with great results in fuel systems for quite awhile now. The instructions on the can say to use it in the oil as well. I can see using it right before an oil change maybe. Have any of you used it in the oil?

I asked the same question a couple weeks ago about mmo, or seafoam. I was told that the bikes actually hold 5qts. and you only drain 4qts. with an oil change so 20% of the additive will remain in the crankcase. I was advised against it. Somebody else on here may have a better answer than that for you. Thats just what I was told whan I asked the same question.

The funny thing is, it doesn't say anything about how long to leave it in the oil.

Just by the fact that Seafoam is a solvent I would think they mean to use it as a flush just before an oil change. Personally, I would not use it that way since there is a quantity of oil left in the engine when you drain it.

Yea Only my Opinion that it's not a good idea. If I was trying to flush sludge from and engine maybe. But not for the heck of it, especially not in a wet clutch. But what do i know about this?> Nothing. It might clean the clutch plates, who knows? The Lube to cleaning action ratio would be in your favor though eh?

Good oil has enough cleaning agents in it. Maybe just change it out more often until it ran clean longer.

I do know an engineer for GM power train, and he always advises against additives in oil, Always. And he always has tons of info to back up his advice, so. I'd go with what he says. He also says never flush anything, just change fluid. Like Trans and coolant. If something is stuck in a crevice somewhere, leave it there until a rebuild. If you change fluids like you should, nothing will be there to flush.

Just my 2 Cents worth, not scientific facts at all.

Like has already been said, I would not do it just for maintaince... If I had svs then I would do it just before an oil change and then change the oil after about 50 miles or so.. Then I would do a couple of quicker oil changes with a cheaper oil before going back to synthetic... But thats just what I would do if it were me

The effect on the clutch would be my only concern, but MS1700 brings up a good point, It may actually clean a clutch that is slipping..hmmmm
