MMO is a good additive but you are right that you don't want to leave it in too long. Its main ingredient is Stoddards Solvent, so it is great for cleaning out the crud in an engine. I used to put one qt of it in my car about 100 miles before an oil change. I don't now as I use Mobil1 in everything except the diesels. It was really great for cleaning and lubing hydraulic lifters.

I'd assume if left sitting for too long it would cause pitting but I'm not exactly an expert either.
So, I bought some Marvel Mystery Snake Oil Extreme 2.0
I poured roughly an ounce or two into the crankcase & the same for what I assume to be 4/5 of a full tank. I'll probably ride as-is for 50-100 miles, throw like 1/4 of the 16oz bottle in the crankcase for an extra few trips around the neighborhood & then change into this proper quart of non-resourse-conserving 10W-40 I just bought, using the rest of the bottle here & there when refilling the gas tank to make sure the top end is nice & shiny...er.
What do you guys think? The mysterious salesman said it was totally legit!
