Marvel Mystery Oil

Everyone I've ever talked to love SeaFoam. But how do you guys feel about Marvel Mystery Oil? Is it worth it or a gimmick? Do you personally use it as a fuel or oil additive or both?

The only place I use it is in my air tools.

I've only ever heard of it being used to unseize engines, never as an additive.

Upper cylinder lubricant added to fuel but very expensive......lots of other choices!!;)

A lot of the old-timers used this stuff for lots of different things. As a fuel additive, add it to the crankcase, one guy I knew would add it to his transmission.
I use it in my air tools as well, it's cheaper than the snap on tool oil lmao.

Great old school stuff, I use it mainly for winterizing engines now.
It's good for many purposes though.

MMO is well-regarded on BITOG, but mostly for use in engines that have been mistreated and are sludged up and/or have cylinder deposits.

If your engine is in sound mechanical condition it doesn't need anything added to the oil; indeed, today's oils are so good they don't need anything added to them to do their job properly. I do recommend using a bottle of Techron or Regane to the fuel 2-3 times a year to help keep the injectors clean and to remove intake valve deposits, but that's about it.

:confused: It's like $4 a quart. Maybe you're thinking of something else?

It does smell good, too good, tempting to take a sip when no one's looking good... Anyways, you use it in your gas and oil? So I assume then you find the bottle's claims to be true?

Around here it's $7.00 a PINT.....maybe you have misread something??:confused:

I use ashless TCW-3 from Wal-Mart for about $12.00 a gallon!!:beer:

Send me as much as you wanna sell for $4.00 a quart...OK?? ;)

[RF Overlord]

VatoZone has it for $5.99 a quart here...
