OK, I know that 303 hydraulic oil had legal problems, and I guess it is not available anymore. 303 was the spec oil for my JD 4020, and I need to pick up another 5 gallons to have on hand. I stopped by the local tractor supply place figuring that the new hydraulic oil would say whether it was a replacement for 303 oil on the bucket, but no such luck. Now I'm more confused than ever, AW 46, ISO 46, AW 32, ISO 68, etc. I thought it would be a quick internet search for
I use the high price stuff in my newer tractors (Hy-Drau, UTD2), but I need some generic 303 type oil for my older tractors. Is AW 46 a good substitute for me, since it seldom gets below freezing here?
