Question

Do any of you have personal experience with Marvel's inverse oilers, like the two currently on ebay:

NOS MARVEL MYSTERY OIL 2 QUART INVERSE OILER Item # 2409501536

MARVEL MYSTERY OIL INJECTION BOTTLE Item # 2409405884

Do they still make those?

Question

John,

Are these things supposed to be oil accumulators or what??

You know, tanks under pressure to lube the engine before startup or when it's oil pressure gets below a set number??? pdq67

I remember a warehouse full of those things. The ones i saw were manufactured by AMPCO, it was described as a top cylinder lubricant, the instructions showed flat head engines.

Engine vacuum pulled the lubricant out of the jar and misted it under the carburetor, they claimed it removed carbon and stopped hair loss.

I did some more research. 68ragtop's description sounds largely accurate. One link I found stated

Quote:
You may have heard that there is no such thing as gravity -- the earth sucks. The Marvel Inverse Oiler works along the same principle. Rather than rely on gravity to drop oil into the top end of the engine, a vacuum line is fitted to the intake manifold and oil is sucked out of the oil container. This works better than gravity feed for a couple of reasons. First, the oil tank can be mounted beside the engine or even below it, instead of higher than the engine. The most important reason that vacuum suction is superior is because vacuum corresponds to the amount of work the engine is doing. We have a vacuum gauge on the instrument panel and find it as useful or more so than the tachometer. From What is a Marvel Inverse Oiler?
They seem to have been used in particular with Judson Superchargers.

I'm still interested in hearing if any of you have ever used one.

I guess I could just add oil to my gas tank like a two-stroke instead.

68ragtop is exactly right. I used to have a '50 ford with a flathead that ran on of these. They really were'nt snake oil! They work for these crappy old flatties!! Marvel Mystery oil has pretty good detergent properties. I think that the mystery oil was the only thing that kept the rings and valves in this engine!

In other words, it is a top-oil dispenser into the intake manifold to help the valves, guides and seals lube as well as adds top-oil into the gas/air mixer that gets down into the rings upon cycling!! And it works off intake manifold vacuum to boot..

I do know that the old Judson vane blowers needed to be lubed like this b/c they included an oil jar to feed oil into the air stream so that the tips of the vanes would be lubed and wouldn't wear off quite so fast as when ran dry..

Thanks everybody that chimed in here b/c I have ta say that I learned something that I didn't even know existed!!! pdq67

PS., and I wish that somebody would come out with a cheap, modern, vane tip/housing not touching blower like the old Judson b/c from what I have only read, they worked very well until they wore out...

I thought we had a cheap, roots type in the little extruded parts, K-F units but I don't even know just exactly if they are around under a different name or not?? Maybe Ken Bell???
