I always saw MMO on the little metal display racks at service stations since the 1950s along with all the other mechanic in a can or bottle additives, back then the oil was single weight and thick as molasses,I think Twisty has it correct as far as MMO is concerned {see below} I never used Sea Foam, because I have not seen it for sale around here if I find it I will try it because of so many good reviews on this forum about it. A lot of people have said using MMO made the shifting easier and the engine quieter. I would probably use the premium diesel oil instead of MMO. since the idea is to get rid of varnish and gum.

Twisty said "You could try an oil additive like "Sea Foam" or "Marvel Mystery Oil" but neither probably have the cleaning ability of a good (premium quality)diesel rated engine oil."

In the late 60's and 70's we use to put a quart or Pint of Diesel fuel in the gas tanks of V-8 cars to keep the Valves, etc clean plus it gave you better gas milage! Too much and it would smoke!

Farmers in the South did this for years with their gas tractors and trucks!

There were gas stations that sold a mix of gas and 3% diesel in the 70's!:clapper:

I pulled a good one with putting diesel in a chevy engine with very high miles on it, I put too much and the engine had too many miles on it, I poured some through the carb and added some to the fuel, I drove it about 100 miles and with all the carbon cleaned out it no longer had enough compression to start. So it is alike Brill-cream, a little dab will do you, on a really carboned up old engine. Havent used any diesel in a gasoline engine since....:goofygrin:
