I would not do it. Dead link John

 

I use it for all other advertised uses but not in the oil...It always seemed like a bad idea to me........WW

 

I would go to 7 eleven. Buy one of those NOS cans they keep cool in their fridges and pour that into your gas tank. It's cheaper than real NOS.

 

Oil belongs in the crankcase, nothing else. I have used it in the past to find exhaust leaks, it is really good for that! As a fuel system additive I'd have no issue.

 

Pull your valve covers & take a picture, then we'll tell you if you need to add anything to the oil.

 

It's just light oil, naphtha, and alcohol. It's nothing special.

 

It's not going in my crankcase, though.

 

Seafoam will break free deposits inside your engine that could possibly find their way into passages that will starve your motor of oil and destroy your engine...within 3-5 miles. Ask me how I know...

 

ive used it with positive results in the gas of different motors but wouldn't put it in my oil.

 

I use it in the gas can for the lawnmower and snowblowers. I also use it in the gastank of the cars and truck every so often to help keep the injectors clean etc. I also put it into the tank of the T-Bird and Vette along with a fill of non-alcohol gas when putting them into winter storage. I've not had any issues with sticking or poor spraying injectors doing this so far.

My 2 cents

 

No. Snake oil.

Here some more for you, if you're a fan of wasting your money on unneeded elixirs:



^My favorite is the "Motor Honey" (3rd shelf up, middle, yellowish bottle)....stuff has GOT to be awesome, with that name!


As for putting an additive in your oil; what, exactly, are you trying to accomplish? Modern motor oils already have all the additives necessary for your car.

Give THIS a read... and notice all of the "build up" inside that 150,000+ mile engine.

 

 

I picked up a bottle of Lucas Super Coolant that said "if Lucas makes it, it has to work"

 

thanks to all who replied w/ ideas &/or opinions .

tom 400cfi's article is must reading and 540 RAT is very good on oil rankings imo.

That ain't true about their electronics.

 

If you're east of the Mississippi, take advantage of the storm(s) off the coast and you'll be able to get all the seafoam you can hold off the beach...for free!

 

Just some anecdotal "stuff" I'll pass on...U decide what it's worth!

We've a local small engine mechanic that warned me NOT to use (that red-colored "fuel stabilizer" stuff) in any of my small engines that sit all winter. He said it would plug up the carb jets and such. Well, I'll be damned if he wasn't right about that! Sure enough, a couple engines where the fuel had evaporated over the winter had plugged jets, plugged with a hard white-ish red residue... Same guy recommended Seafoam instead.

I didn't use anything in my motorcycle one winter. The jets were plugged in one of the carbs the next spring. (Tank had 93 octane, w/ 10% ethanol).

Never had any issues in the spring in engines with Seafoam mixed (as directed) in the fuel.

I don't know what is in Seafoam, but it smells of alcohol and something else??

An auto mechanic I knew put something like a quart of kerosene in a Chevy 350 "to free up the lifters and remove sludge, etc." Well, after running it for a few miles, it lost all oil pressure, and before he could get it back to the shop the motor locked up and was ruined!

I don't know what is in Seafoam, but if it is alcohol (and Naptha??) it sure as hell is going to reduce the viscosity, just like that kerosene stunt did...I think. YOU can put it in you oil, if you want to. But! It ain't ever going in my oil!

For what its worth...

 

If the engine is clean, it won't blow out smoke.

that's not true look on youtube for the video on brand new engine
