How do you choose steam oil? Is there a big difference?

Right now, we plan to stock two different oils, because we have a saturated engine coming into service in 2022. But we also have two different servicing locations, so that means stocking two different inventories at two different locations. Is this really necessary? If we have oil satisfactory for our superheated engines, can we just use the same oil for the saturated engine?

I would be concerned about using oil for saturated steam in a superheated engine but less concerned about going the other way. Bill Pettijean was the tribology guru in the industry and blended his own brand of steam oil - Green Velvet - in different formulations for both. I don't know if his products are still available but I found them more than satisfactory. He may not have a Danish distributor....... but as commercial refineries make less specific varieties of oils opting for multipurpose blends I'd want to be very careful about a decision.

The short answer I have universally heard is no. The reasoning is the lower temperature of the saturated steam will not properly disperse the oil and it won't be as readily carried to all the devices needing lubrication............mld

Bill Pettijean's formulas live on and are manufactured and distributed by Brennan Oil Company of Durango, Colorado. They will ship overseas as far as I know, or at least I know they have to the UK. They can be found online and are great to work with. You can probably guess why an oil company in Durango, CO manufactures and distributes steam oil.
Sapona Min steam oil, for superheated steam and PB&J 1000 are the two major blends.

No website for Brennan Oil Co. No mention of offering steam oil anywhere. If they want to sell that product, they might consider marketing it.

I sent a FB message to see what I can learn.

Brennan's is a family run small business, and they at one time did have a website. Their bulk oil facility phone number is 970 247-3054. Kegan Brennan is who typically handles all the steam oils.
Hope that helps.

Thanks so much. Will anyone dare say anything specific about the oil in the photos?

This is not useful at all, but I was curious that Gulf Oil was still being sold as they disappeared in the 1980s (growing up in the early seventies my tiny little town had a Gulf station), I found out that in Europe Gulf Oil products are licensed to this group: https://www.hindujagroup.com/ Gulf Oil was one of the so-called Seven Sisters oil companies, and is the origin of the Mellon family fortune, including Mellon Bank and the current Pan-Am Railroad.

Never seen them in use in the USA and know nothing about them.

Isn’t Brennan’s the main distributor of Green Velvet?

Yes. Best stuff I have ever used. We use the Sapona med 680 and PBJ at the Colorado railroad museum.
