Title: Used for years is great
Review: I have used royal purple products since about the mid 90's I love the results on everything I have used. I used this in my 60 gallon overworked 15 year old Campbell Hausfeld compressor that I have used daily in my shop. I change the oil in it once a year never had an issue. I tried another brand to see if I noticed a difference and I did it runs at 199-205 degrees on royal purple oil, on the other brand Mobil I think it was at 220-225 degrees I am sold.
