Re: marvel oil

Kinda doubt you need to put Marvel in the fuel. If you have a two stroke motor, and are mixing at 50:1, you already have the lubrication needed. The Sta-bil is used to help keep the fuel "fresh" and it also disperses water. Having said that, lubrication is always a good thing for an outboard as long as you don't over do it.

Re: marvel oil

I think StaBil actually is a fuel conditioner, and it takes water and turns into alcohol--which is burned. Many people put StaBil in their tanks for the winter--thinking it'll keep their 90/10 gasoline/ethanol from breaking down. Unfortunately, StaBil actually breaks down faster than the 90/10.

Marvel Mystery Oil is truly a mystery. As the name says, it is an oil, and it's multi-use. You can put it into the crankcase of an old car/truck, and it'll dissolve grease and gunk--to be flushed out with the oil. You can use it as a penetrating oil--to break loss rusted bolts. You can also put it in your gas tank. You can essentially do the same thing with Liquid Wrench, Seafoam and some other products. I've never heard anything bad about it, however. I do think it has a place on an old truck engine, but probably is of little use in boats.

Re: marvel oil

While I've never used the Mystery Oil per se, I can attest to the wonders of Sea Foam. It is without doubt, the best $10 you can spend on an old outboard. There's almost nothing it can't do. I would highly recommend it for bringing long dead outboards back to life. It noticeably improves idle, reduces noise, and just generally smooths things out. It also works great in your car/truck. There are tons of vids on you tube that can show you how to use it. IT comes in both liquid and spray forms, both of which are great. Sea Foam also makes an aerosol product called Deep Creep, which is sort of like WD-40 on steroids and it also works great as a penetrating oil and engine decarbing agent. Sea Foam = Happy motor

Re: marvel oil

I have used SeaFoam a couple of times. Other than the acrid smoke it makes, I have never noticed any real change (good or bad) in the running of the OB. My test sample has been narrow and I did not pull the heads to see if the carbon was gone.

Re: marvel oil

Question. What's the difference between Marvel Mystery Oil and good old ATF ?? Sounds like they both do the same things.
