I bought 3 jugs, 2.5 gallons each of tractor supply "traveler" ND 20wt and ND 30wt oil. Got 2 jugs of 20wt an 1 of 30wt. They were on clearance for $3 each back around 2015. Those 3 were all they had or I would have bought more.
I change the oil about every other year because it's so cheap.
Use the 20wt in the electric air compressors since they turn on and off as needed and the oil barely gets warm.
Use the 30wt oil in the gasoline powered compressor as it runs continuously, it unloads but doesn't stop until I shut it off or it runs out of gas and the oil gets rather hot.
I'm almost out of the 20wt, probably not enough left to complete another oil change.
ND 30wt and iso100 compressor oil are easy to find.
But the ND 20wt seems to not be readly available.
Any one know a good cheap source for ND 20wt oil or iso46 oil?
