I've been running Marvel Mystery Oil for 22 years and 1200+ hours in two high time engines, an 0-320 in the Tripacer and an 0-200 in the KR without sticky valve problems.  MMO recommends 4 oz to 10 gallon of fuel but I run 4 oz to 5 gallon of fuel and a pint in the crankcase at oil change time.  Other fliers at my airport were reaming valve guides and replacing cylinders during that time for sticking valves.  I have no scientific proof that it works but I'm a believer.  It also keeps my plugs running clean of lead deposits.

As always, YRMV.................
