Default Re: Marvel Mystery Oiler

Hello, I would like to have a real Marvel mystery oiler for my Model A. Unfortunately they are hard to find and if, then very expensive.
Yesterday I found an offer for one that is supposed to be for a JUDSON SUPERCHARGER MERCEDES 190SL . In the photo it does not seem special and the box does not say anything about this purpose. Does anyone know if I can use this for the Model A?

There is a less expensive alternative to the Marvel oilers, the Ampco lubricator. These are NOS, somebody bought a warehouse full of them that were leftover from the '50s or '60s, they aren't reproductions or new manufacture. Maybe that would work for you? They do look kind of interesting.

One thing that's important, the injector tip needs to be through a carb plate just above the intake, basically. Installed at a manifold port some cylinders will be starved while others get too much and plug fouling occurs.

Hi crankster,
the Marvel oiler operates inverse to vacuum - high vacuum closes the clearance between the needle & seat, and delivers "less oil". When vacuum drops, when under load, the clearance increases delivering more oil.

The Ampco does not have this feature, so when vacuum drops it delivers a bit less oil than when vacuum is high.

So, one can nearly say, the Ampco oiler is nearly only half as effektive as the Marvel Mystery Oiler.

Default Marvel Mystery Oiler

Well, to be honest, I just pour it in the gas tank and don't worry about it. About 4oz per 10 gallons. It does work to keep valves from sticking &c..

Dad used MMO in the 80's to free a locked JD model A tractor. It took about 6 months, but freed a completely stuck motor that had been in a field for 20+ years. I use it in my Farmall 450 and Edgar's 30 Fordor I drive. 4oz to the tank.

Dad used to say MMO would mend anything from a Ferris wheel to a broken heart!

This is the case with the Ampco because this dosing device drips oil droples into the intake.
With the Marvel Oiler, this is different because the oil is swirled with air beforehand and oil mist is sprayed into the intake. -


But I would also very much like to know the question answered, whether there are different Marvel Oilers, for suction engines or turbocharged engines?

Asked directly, can the oiler shown in # 21 also be used for a normal A engine without rebuilding the oiler?


Thanks at all in advance!

Nein, Macht nicht. Anything introduced or "injected" must have a central point high in the intake so that every cylinder has a roughly equal charge distribution. That's why they use a carburetor spacer or injector plate for the flathead and other engines.

I just add 4oz. to the tank when I fill the tank. I also ad 1oz. of Sta-Bil 360 to deal with the Ethanol (California). I have noticed a huge difference in the way the motor runs, smoother, faster, and cooler. I think adding it to the tank also benefits the tank as well. It should stop or slow down any rust that might begin to pop up inside the tank.

Does anyone else use the Sta-Bil 360 product, and if so, what has your experience been with it?

Regards
Bill

My 1927 Willys-Knight has a JAY LUBRICATOR. Are you familiar with it? How does it rate against the Marvel? Thanks

I bought and imported an old MMO oiler from the USA and unfortunately found that the brass valve inside was destroyed by corrosion.


Do any of you know someone who restores MMO oilers and who sells spare parts and sometimes has them remanufactured?

I can not do anything at all with this oiler and would be very happy about a helpful hint.

Back in the 1950s-60s there was a product called Red-X which was similar to MMO, Red-x also sold a "upper end lubricator" which was also tied into the intake manifold.

I had received an address for an MMO restorer here in the forum. He sends spare parts. I had positive contact with him, but I can't find the email address anymore.

Who can supply spare parts for the MMO oiler?


Need help! I bought and imported an old MMO oiler from the USA recently and unfortunately found that the brass valve inside was destroyed by corrosion.

Hallo und guten Tag,

my friend means exactly the small valve shown below, which regulates the flow rate of MMO.

The floating steel cone foot was firmly corroded in the brass pan and broke off when I tried to loosen it.

Wanted new or used, dead or alive!

Many thanks in advance for any hint,
Werner
