Marvel Mystery Oil Valve Lubricators
![[Deleted User]](https://openforum.hetclub.org/applications/dashboard/design/images/defaulticon.png)
I remember hearing about Lubricators that could be installed on a Hudson engine that would lubricate the valve guides and help them last longer. I think they used marvel mystery oil. Does anyone know the details on these lubricators. Where can you get them and how do you install them. Thanks for any info. Rob Fayette

The lubricator was a mount and glass jar that was fastened into the engine compartment. The top of the jar had a tube that ran to the bottom and was open at the top. Usually a rubber hose was fastened to that and the other end was connected to a vacuum port on the intake manifold. Marvel Mystery oil was added to the jar. As the engine ran the oil was drawn into the intake manifold and subsequently to the valves. I have seen another setup that used a carb base adapter which had a input nipple where the hose from the oil jar connected. My Dad was a big supporter of MM Oil and moved one of the vacuum connection jars from car to car. He finally sold that unit with a Corvair convertible.0 -
YEA. I have 2 NOS in my garage, but unfortunely the adapter plate is for single barrel carbs. The were a little more involved than just sticking a tube in a jar tho. They were used mostly in the 30's and 40's.0

Rob, My 1954 Hornet has a MM-oiler and it is plumbed into a vaccume port below the carb. Works great and is metered in extream small amounts. My car has used only 1 pint of MM in the last 2000 miles. With all the different types and grades of gasoline these days, I think that it is prudent to use one on our old cars. Eastern states have grades that are 84 or85 grade while here in Calif. there is only 87 as our lowest octane. Not knowing exactly what is in the gasoline today makes one want to back and become a chemist just trying to figure out. Good luck.

I have a plastic hood emblem from my 46 comm. that has GITS pat. no. etc in the casting. who is GITS ?0

you can buy them new,they have adaptors for many different cars too.

The concept sounds appealing, but in actual fact all you are doing is lubricating the cylinders, and perhaps a small amount around the top of the inlet valves, which don't need it any way. think about - how much oil is going to be deposited on the exhaust valve guide? The charge has burnt, and extremely hot as it goes past the guide. There is no vacuum around the exhaust guide in any circumstances. Sorry to be a killjoy, but I fail to see any way lubricant can be dispersed around the exhaust valve guide on a side-valve motor. It certainly won't do any harm, but like most add-on items, it is of doubtful benefit.

Geoff. Now you know why I have 2 NOS oilers and have had them for years. Always felt they were of questionable value. More junk collected over the years.0

As a side-line, I don't know how many of you remember the era when water injectors were touted to be the latest and greatest add-on, guaranteeing extra mileage, cooler running, cleaner plugs, no carbon formation, no burnt valves, etc. etc. I had one of these on my 1928 Essex for 10 years until it siphoned half a gallon of water into the motor one night, when I threw it away. The only thing I ever determined was that it did actually use water! But there was no detectable difference in any of the above factors, and the car has since run another 35 years in exactly the same manner, with minimal problems of any sort. I have had the same set of plugs in for over 80,000 miles. A friend has a "Fuelmaster" unit on his car which is guaranteed to overcome the problems of unleaded fuel, and is supposed to raise the octane rating , eliminate pinking, eliminate valve seat recession, clean the plugs, etc. etc. The only honest evaluation he can give me is "I'm not having any problems with it". Well, I'm not having any problems without it! Oh my, I am getting cynical in my old age!

I have used MMO in several Hudsons I have owned. I had an MMO Inverse oiler on my 51 Hornet, and used MMO in my 1946 S6 Cl Cp. I used the MMO in the 46 to keep valves from sticking, which the would do from time to time. Once I added the MMO I never had another valve stick. The inverse Oiler delivers MMO inversely to the amount of vacuum available. Hence it delivers MMO in much great quantities when the engine is under load, and very little at idle. Below is a paragraph I copied of a piston engine aircraft site. Dan
Use the directions on the back for amount to put in the fuel per gallon of fuel (4 to 6 oz. per 10 gallons of fuel). MMO goes through the carburetor as a droplet, broken up like the fuel. When it enters the combustion chamber and the gasoline ignites, it is vaporized and soaks into the carbon buildup on combustion chamber walls, valve guides, around the valve stem, and on the spark plug. It soaks into the carbon and eventually loosens it up and it goes out the exhaust system.0 -
Makes a great air tool oil when mixed with the proper oil , , ,0

I have used it for years in air tools, works great.. As I posted earlier I have 2 NOS. FREE to anyone who wants them. You pay shipping.0

We used MMO in our Skymasters mixed with gas because the continental IO 360's had valve sticking problems. It seemed to help with the sticky valves but fouled the injectors. The fouled injectors ruined at least 1 engine. Part of that was a crappy mechanic, but there is no doubt the injectors clogged up much more on the planes we ran MMO in the gas, than on the other planes. We also tried mixing MMO in the oil which seemed to help with no noticeable adverse effects. Man was that fun.
Have a nice day

Back in the '70s I would use MMO to lubricate and preserve our R/C model airplane engines after a thorough cleaning until the next time we flew. I learned this trick for the '50s national stunt champ, George Aldrich.
Peace,

It must a Marvel, and a Mystery, how the oil doesn't get burned up in the combustion process. That would be scary, having bad injectors in an aircraft engine! Much simpler to pmix the stuff inwith the gas, than having it as an add-on. I would like to see some scientific evidence as to the efficacy of the carbon removal from valve stems and guides.

Here is a MMO setup on my 51 Commodore 8. Wouldn't this be considered a vacuum leak when empty?0

Here is the carb attachment.0

Just as an aside, how many of you knew that the same company that was responsible for the Marvel carb was also the company that produced the famous Marvel Mystery Oil? Wierd, but true.0
