I remember my '84 F150 after 150,000 miles and about 13 years would occasionally get a very loud lifter tick (or so that's what I thought it was) on start up in cold weather. After a while it would quiet down. And that engine had Rislone every oil change. Hmmmm.

This is from a previous post by Flash:
MMO is a mineral oil carrier used to deliver solvents and chlorinated hydrocarbons. It's basically a 20wt oil with solvents to thin the oil and has a flashpoint about 350F. Years ago when upper lubes were considered useful, MMO was a good choice. Valve recession is no longer a problem in modern engines using fuels that no longer contain tetraethylene. Considering the composition of todays oils and the complexity of the formulations, I would suggest caution using any additive who's formula is as old as your grandfather. You might just upset the additive base in your oil.
I'm sure MMO is fine for oiling air tools, etc. but there's no way it's going in my crankcase.
