March pump SAE 20 oil

[WalterAtMarchPump]

Oiling the pump is not 100% necessary unless its being operated in a bad environment like very dusty or very humid where it can start to rust. The motor Mfg have told us they are lubricated enough to last the lifetime of the pump for continuous duty operation. (according to them that would be between 3-5 years of nonstop running)
If it makes you sleep better at night I just recommend to all that call here to get some sewing machine oil (that 3-in-1 oil is perfect) and put a few drops in once a year for the average person operating it inside their home. Anything else would be your own judgment call.

Thanks Walter. You have put my curiosity to rest. It was one of those subjects that was a non-issue until I oiled the pump and couldn't find an literature to determine what was proper. I'm glad I can sleep tonight.
