Default Re: Marvelous Mystery Oil?

You really don't need MMO as it only turns into unburned hydrocarbon emissions and soon develops into a varnish above the first [compression] ring of each piston. Why carbon up the churn any more than you need to by burning gasoline?

I do wonder if MMO 'seals' in the compression a bit. Like my weed string trimmer two cycle likes 40:1 and my chain saw likes 50;1 and the English made Saegull outboards like 10:1 oil to gas.


Just like a two cycle engine [O/B] not all the oil burns away and the majority comes out as blue smoke and an oil shine on the water on the way out of the engine after lubricating and cooling the churn's innards.

So why do exhaust valve sometimes stick open? Maybe because the are carboned up? From what? Burned oil? Burned oil like MMO? So are we exacerbating the problem by adding stuff that does not burn away nor add any additional hp? Just a thought.
