I had a former boss who swore synthetic 10w40 was the same thing as JB Black Gold 🤦‍♂️ he literally acted like I was some kind of primadonna because I wanted vacuum pump oil for my vacuum pump. Dude even went as far as trying to pour synthetic motor oil into the shit and contaminated a gallon of good pump oil. He really was convinced they were the same

I have to get water out of waste veg oil long term use for using as fuel in a engine in a vehicle, under a vacuum what pump is suitable for it? Thanks.

Jim on residential refrigerators we have to connect vaccum pump refrigerant tank and high and low side hoses and pull a vacuum on it all to avoid infiltration. The hydrocarbon refrigerant hoses are even smaller than the standard 1/4 hoses. There's got to be a better way?

What do you think of rx-11 flush, followed by a bunch of nitrogen?

I have heard you say that moisture in a system takes TIME to evacuate, "..no matter what you're using." Is that true on a system that's been open to the atmosphere somewhat but not directly had water put in the system? I would think that the better hoses and gauge would help in any situation.

As long the systems open, the oil will act as a sponge and pull moisture. Poe oil is worse than mineral oil.

Great videos Jim! Any thoughts on putting this into book/pdf form?
