Adding Seafoam to oil, anyone?

[radek22]

Just curious if anyone tried adding Seafoam to their motor oil - what amounts and with what results.
If so, should one add it to new oil only, or is ok to put some in to older as well?

Cheers

I have never heard of doing this. Sounds like a bad idea, wouldn't Seafoam break down the oil? I've seen people use diesel fuel to flush out an engine though I wouldn't do that either. Ray

If you want to add something to your oil to flush it before an oil change,
I would use Marvel Mystery Oil instead of the Seafoam.
Seaform might work in your car/truck but they don't share the transmission and clutch with the oil like the GSes.

I'd be pretty careful about doing that. You don't know how that going to affect all your old seals and gaskets, nevermind the clutch fiber plates.

Some people run a little Seafoam in the oil for about 50 miles before draining it for an oil change to help flush things out. Not sayin' it's the best way. I think the Seafoam people recommend it but they might not be talking about motorcycles with a wet clutch.

Thanks for your responses.
I think I'll stick to adding it to gas only.

Well 5 or 6 years ago I contcted Seafoam on this subject and spoke with one of their chemical engineers. He informed me that as the formulation is derived from petroleum it is 100% compatable with oil or gas.

I always use it on any new to me bike. I put it in the existing oil and run it 500 to 1000 km before an oil change. You would be suprised what crap comes out.

I have never experienced any difficulties, no clutch slippage, no problems whatsoever.

Whether in gas or oil, it is good stuff IMHO so don't be afraid to use it.

And no, I am not a spokesperson, affiliated with Seafoam or in anyway a spokesman. Just a satisfied user.

If your motor is in that bad of shape, just tear it down and rebuild it.

Seafoam is not magical mystery oil (no pun nor reference intended), nor is it snake oil. I would use it, but only prior to an oil change.
And for certain, if the alternative was an engine rebuild, the Seafoam is in there. 100% of the time.

I add to oil on every bike that I buy. I do this because I have no idea what oil has previosly been in the bike and how often it was changed.

I spoke to two Sea Foam reps who couldn't answer the "safe for wet clutches" question, one immediatedly called the plant and spoke to "expert". The resulting answer was same as above, 100% petrol based product, will not harm wet clutch.

I add the seafoam, 2-3 oz to the crankcase before a 40-50 mile ride and then come home and change oil and filter. This is always done before the valve adjustment and I have never had a top end that wasn't perfectly spotless upon opening the valve cover.

I then button everything up with fresh filter and Rotella 15w-40 and all is good to go.

I will say that the oil that comes out is usually nasty black and terrible looking.

My .02 and never had a problem. I am sure that other things would work but its just easy for me to dump the 3 oz in the crankcase and then the rest in the tank and I'm done. $7.00 piece of mind.

GSes are always perfectly clean inside, aren't they?

Sure…except if you spill some chips and beer.

[tkent02]

Usually I just spill gasket chunks.

I find that changing the oil as scheduled provides for more than sufficient engine cleanliness.
