Great lubricant for reviving old engine
This stuff was awesome for bringing back an engine that had been sitting for 5 years. Soaked through the spark plug holes and under the valve covers. 3-5 days of waiting and I'm hand turning the crank easily with one hand. It was super smooth turning too no bumps or stops or grinding, smooth as glass. I bout 2 16oz bottles which was more than enough, this stuff is low cost and effective. And it smells good to boot, minty fresh.

I put this container of Marvel mystery oil in my 1952 Ford 8N tractor. It has never run better. This product has been around a long time, my first use and now I know why it has been around so long..

Been using it for decades -- I like it.
I've been using MMO for decades -- I use it in my Vintage Chevy Trucks, my late-model vehicles, and also in my small engines. Today's gasoline is very Dry, compared to gasoline from the 1970s & 1980s. Add Ethanol to that trend, and today's gasoline is VERY Dry. Modern engines are supposedly engineered to withstand that, but I don't have many "Modern" engines. I prefer to provide "Top-End Lube" to ALL my engines, especially my 1985 Chevy truck, my 25-year old Cub Cadet, & my 30-year old Briggs & Stratton "L-Head" lawn mowers. Also, I think that MMO does a fairly good job of cleaning injectors & fuel deposits -- probably not as good as Techron, but good enough for me. So, I add about 10 oz of MMO to a full tank of gas -- I wait until I park the truck, then add the MMO, then let the truck sit for a couple of days to allow the MMO to spread throughout the tank.
