We have left this thread out of our stream of communications.
This was (is) a valuable thread to keep alive. Let’s try and
keep some fresh, helpful, time saving, improving quality, and
suppliers, coming along on this thread.

Just changed my vacuum pump oil last weekend. We historically
don’t do this often enough. I try to change it when I figure
I’ve got 10 to 15 hours of run time. The tip is the oil I use
comes in a gallon can, and is less than $3 per gallon. A bit
hard to find, but just 10 weight non-detergent oil! I was
dropping by Grainger’s occasionally for a $5 quart of vacuum
pump oil! Quite a difference in price. Some of you may remember
Goldspells casting- Steve Pearson. I need to credit him with
this tip. His method of cleaning, after draining the old oil,
was to add kerosene to fill level, operate 5 minutes, and
repeat. Continue process until the kerosene is fairly clean.
Then refill with 10 weight non-detergent oil. Make sure you
order non-detergent. The product I found is a Union 76 product,
UNAX AW 32. Auto parts stores don’t carry it, but could order.
It’s easier to just look in the phone book under
Oils-lubricating, to find your gallon.
Favorite tips is alive and well!
