Many oil Blenders such as, Warren, Davis (multi locations),[ Cross Packaging (Extreme Pure Flow THF, Extreme Ultra Premium THF) AKA UNIMARK (NAPA Premium Universal) both located at 484E. 6th St, Smackrover,AR. (I think) they state they meet or exceed JD20. When looking at many MSDS's, things start looking funny when comparing them to JD's HYGARD or Chevron Ursa MSDS which appears to be who mfg's HYGARD. HY and Chev are highly refined mineral oil (c15-c50), Chev= 75-95%, HY= 80-100% weight mixture, AND HERES THE BIGGIE both have 3.6% Zinc alkyl dithiophosphate (ZDDP) the BEST Anti Wear additive (See Valvoline Racing Oil). The others show no Zinc,? <.5%, ) 0 -10% and etc. on the componets line which could be as little as 0%. Now here is the catch, IF ANY ZDDP is present I think it must be listed under Section 15, of the Regulatory List, which they did not. Other than Deere or Chevron none of the above have Zinc based on the assumption, it is not listed in their Section 15. NAPA Prem.($46) states 5-15% Proprietary additives and list no Zinc, so whats that mean, try and find out LOL. Trying to keep this simple, it is my opinion that most of the low cost blendings are of a lesser quality distillate and refinement with a less high quality anti wear componet, but suspect they have anti foam, rust inhibitors and seal protection. What I want in my Dozers and Tractors is wear protection, seals/O rings are cheap compared to gears,shafts and bearings. I was told that Chevron is about $75 per pail compared to $55 for HYGARD. I'll stick with HYGARD for now as anybody can state (Meets or Exceeds) I trust Deere/Chevron, Google or request MSDS's and decide for yourself.
