Engine: Ampco Inverse Oiler

[62 Lark]

Hello folks, This is for those that are dealing with ethanol in our gas and want some valve and upper cylinder lubrication. I installed this Ampco inverse oiler using Marvel Mystery Oil. I plumbed it to ported vacuum above the throttle plate . It works well and the atomizer is adjustable with a mixture screw. Socony Mobil had a similar kit that used their product called Upper Lube. This was an new old stock eBay find over five yeas ago with no complaints so far.

Here's the one I have in my 1953 Big Six. I had it poorly adjusted when I ran from Connecticut to Maine= 350 miles. I went through a full quart. It didn't hurt a thing. I've been running them for many years in my VW's. I've had to dis-assemble an engine some years ago at it was made easy due to the oiler. Very little carbon buildup.

Looking for input: Do these units work better than pouring a bottle of MMO in your tank every so often ? I've never seen or heard of these before. Comments ??

The ones RadioRoy has pointed out are for VW and then a generic one. If you go to their website they have a variety of injector kits to match many makes/models. I asked for an injector plate kit for mine and it was provided though not listed.

I would call it a convenience item. The oil gets atomized in the intake manifold but I think adding it to the fuel tank likely does the same.

I'm surprised at how few people know about them. Even my engine builder was surprised. I saw enough of them "back in the day" that when I finally got one of my own I wasn't mystified.

That is Great news 53Pilgrim, the good 'Ol American Co. Ampco is still around, and still making and selling them and for HALF of what resellers want on eBay!

That is a great alternative to adding lead or other additives to the fuel, installing Hard Valve Seats, or buying expensive Real Gas etc.

That is very similar to the "New" Frantz Tissue Paper Oil Filter Co. being revived, and producing New improved 1 Micron Filtration Systems primarily to save dumping the huge Crankcases full of Engine Oil in Diesels by "Cleaning" it and prolonging changes.

Glad this has sparked, or should I say fueled a good mixture of comments. All the best !

I believe the current supplier is just that- a supplier. The basic "kit" consists of the jar lid/regulator and copper piping with some generic hardware all leftovers from the 1950's. The new supplier makes the injector plate kits to fill each order.

Thanks for posting about this. I was not aware these were still produced.
Nice day to all.

My friend, Ed Jones, had an NOS one on the shelf and said he believes he has another one. I will put it on my M5 someday.

FWIW - I purchased one of these units, not sure yet if I'll use it, but thought someone else might be interested. The guy selling these, George Folchi, was very helpful and was able to determine the correct injector plate to fit the Stromberg 2 barrel in my car. These are all NOS in the original packaging from 1952. Less than $100 delivered for the package.
