Gas Man- I've even used Seafoam* in an old air-gun that was gummed up, runs like new now..

 

Not that I care, just curious. Is there any chemical or functional difference between Seafoam and Marvel Mystery Oil?

 

MMO* I use in my Flathead to help with the crappy P4 gas. .. But would not use it to stabilize gas for long term storage..

Where as with correct amount of Seafoam* I can safely store gas for 2 years..

Seafoam seems to work instantly on most things, MMO takes a little time to do it's thing..

Both are great for cleaning & lubricating also..

Seafoam is one of those "snakeoil" things that actually works. It does everything it advertises to do. GREAT STUFF!

 

Yes it is great stuff !!! & Once the can is open, it has no expiration on shelf life, like Sta-Bil* is only good for 1 year after opening bottle..
