Marvel Mystery Oil


Recommended Posts

My experience with Marvel Mystery Oil began in 1960 or so when I bought a second-hand Judson supercharger for my MG TD. The kit came with a bottle and drip-feed arrangement that connected to the intake side just behind the suck-through SU carburetter (<-- BritSpell?). Once when I was filling the jar (every 250 miles or so as I recall) I dripped a bit on the hot exhaust manifold. It made such a sweet-smelling smoke that I habitually dripped quite frequently.

 

I got another Judson supercharger for my Morris Minor 1000 woody wagon (Traveller). It worked marvels there, too. When I sold the wagon, someone stole it off the lot and drove from San Diego toward Las Vegas. I got a call from the CHP in Victorville, telling me the storage charges were mounting up. The thief had not known about replenishing the Marvel Mystery Oil tank, had run it dry, and the supercharger bearings melted. Not my problem, thankfully.

 

My mother's car sat for a year after she quit driving, and when I started it up it had one collapsed lifter that wouldn't come clean. I put a couple ounces of Marvel Mystery Oil in the fuel tank and in the oil sump, and in five minutes it opened the lifter and raised my spirits. It's a mystery why it's such a marvel.

 

I hesitate to put anything in the gas tank f my modern mustangs for fear it will contaminate the MAF thingy. A few ounces in the fuel tank might be one molecule too many. A few ounces in the oil sump probably won't even thin the oil much, and there's always the chance you'll drip some on the exhaust manifold for that delightful aroma.

 

I still have a pint in the garage. Sitting there it doesn't do any harm at all, that I can see.

Cured the lifter tick I had in my 92 Dodge Stealth.

I recall Marvel Mystery oil was recommended by Pratt and Whitney for use in the PT-6 turbine engines on the Beech King Air I used to fly, and I read that in the "owners manual".

 

Using that logic, I would be very careful about using ANY additive in ANY vehicle unless it was directly recommended by the manufacturer. (Or you have proof positive it works and your not concerned about any issues that may arise.)

 

SGT owners can attest we've already had some problems with octane boosters!

 

I'd say go by "the book" and leave well enough alone!

I use it to oil stuff around the house, especially precision stuff. It's a great "top oil" along the lines of Bardahl and Winns, but it's not needed in today's engines. It's great for breaking rings loose after a bad overheat, or for sticky valves and other stuff that's not going to happen to your new car.

I still have a marvel mystery inverse oiler they called it, used it on my 1970 mustang mach 1 back in the day. It worked off vacumm I believe, held a quart of oil and you could adjust the amount you wanted to go through the carb while you drove down the road. Kind of a kool deal back in the day.

Used to use it in the dashpots of the twin SU carbs in my old MGs. I have heard you can put it in the gas tank, but with the catalytic converters...wouldn't touch it.

 

 

I agree but it works great in the gas !! In my old truck when purchased it the gas was old so I threw in the red marvel and some dry gas. I ran it dry filled it back with more marvel and carb cleaner changed the filter and never had a problem.
