Marvel Mystery Oil

I was told to add Marvel Mystery oil to my gas tank and oil when I change it to help clean and lubricate my engine on my Super A. Is this just a myth or true?
Thanks
 
I always add a few onces to the gas every time I fuel up. I've never had any carb/valve/ring problems at all. Actually I am still running an un-rebuilt engine in both my Super H that I've had for over 20 yrs and my Sup A my grandfather bought new. Also add about a 1/2 qt to every oil change.. once a year.

cris: Do you also burn money? Kick the habit, 90% of those additives in auto parts stores are about the same as burning money.

I've never used an engine additive in my life time, probably got more hours of service out of my engines than most folks. Anyone that tells me they've got a letter series tractor with an engine that's never been opened. You also know he never did much with the tractor.
 
I have never added any thing but lots of gas to my fuel tank. Is this something that I should start doing ? The reason I ask is the gas is unleaded I under stand that they added lead to gas for lubrication. I use my M for Cutting hay
It gets lots of hours a year not hard hours but it does earn its keep.
 
i throw a jug of marvel oil and a jug of sta-bil in my fuel barrels just before i get fuel delivered. dunno if it helps, but it sure dont seem to hurt anything. seems like the new fuel blends do get stale quicker if they sit too long, and if they sit in the motor too long, have a habit of pluggng up the carb.
 
Mike: Lead was added for high performance, high rpm engines, your M is neither. I've been running gassers 35 years, no lead added.

Lead supposedly lubricated the valves, well the bottom end will go long before the valves. I've seen the bottom end replaced twice before head was done.
 
Have you seen marvel myster oil from Mexico? Looks like the real thing. Probably isn't. One dollar in dollar store.
 
Hugh, I've pulled a 273 with a kicker and 16' wagons up and down hills for mor than the last 15 yrs kicking out over 5000 bales a year, plus pulling a disk that the Oliver 1600 grunts on goung up a hill. While you may have much more experience with these tractors, you do not have my experience. And to call me a liar is a dis-service to both of us. Mike
 

I also have a 1953 Farmall Super A that still has the original unopened engine. It was my grandfathers primary tobacco and hay tractor for 40 years. He plowed, disced, set tobacco, cultivated, and cut all of his hay with it every year. He raised 15 acres of tobacco, 20 acres or so of hay and always had 10 or so horses. The tractor did not see an easy life but was taken good care of. The internals are all original, the only things that have been replaced are external items, manifold, carburetor, generator and I believe a distributor shaft many many years ago. It still doesn't smoke and starts on the first or second rotation every time. If you run it really hard you will get a small amount of blowby out of the crank case.
On the other hand I have a 45 Farmall A that was my great grandfathers and it wasn't worked very hard at all, and it has been overhauled twice, When my grandfather bought the Super A the older A got demoted to just pulling wagons for hauling water, hay and tobacco, because they favored the hydraulic lift on the Super A for implement work.
