Hey all,

I was wondering if anyone has any recommendations for what type of oil I should buy for my 1956 Probat UG 22.
According to the original Probat UG22 manual, it recommends "Shell Macoma Oil 76 or similar", but I definitely cannot find this online.

Any advice would be much appreciated!

Welcome to HB!

Roast Co in Oakland has used and refurbished/sold several UG22's over the past 15 or so years. The owner could probably tell you what works best.

I'll also link a nice Google Drive collection of practically everything Probat at the bottom of this reply. Their manuals recommend a light penetrating 3 in 1 oil.

Probat USA has a toll free number: Phone +1 877-683-8113


Highwire Coffee, also in Oakland has used an UG22 for close to 20 years. I imagine they might be willing to make a recommendation.

I cannot find Macoma 76 either.
But there was a Macoma 75 that these days goes by the new name of Omala 320.

See this *.pdf: https://vdocuments.mx/download/?url=864 ... vi&t=dl037

They come in 5 gal. drums. https://petroleumservicecompany.com/she ... llon-pail/

Thanks for the responses, and the help!

I got a hold of Probat USA, and this is the oil they recommend:

Mineral, SAE Grade : 140, 1 gal Jug

Now it is time to replace the old oil in the gearbox with fresh oil. I think I can figure this out on my own, but if anyone happens to know any youtube videos or resources that help explain the steps to change the oil, let me know! Sounds like Highwire and Roast Co may be some good options here.

If that's what Probat uses, it should be OK.

It is more or less like a car's gearbox, depending on how long it has been since the last oil change.
You'd need to see if there's a maintenance log for yours from previous owners.

Like any machine with gears, oil needs to be changed once every XXX hours running.

Basically you drain the sump and check the old oil for bits of steel with a magnet.
If you get too much residue and/or metallic bits, you flush it with the appropriate stuff, rinse it once or twice till you get no metallic residue and refill.

I'm sure the people at Probat can explain how they do it.

Best,

CIV
