MSDS is pretty lackluster, does have some esters and amines.
Have dealt with them a lot over the 90s...their sales manager was doing a perpetual fill in his Holden V-8 with M1, and 5,000km UOA, and additive (of course) top-ups, was an interesting side project.
Had a hydraulic system on an MDF plant that I was commissioning, that held 5,000L of oil, and unfortunately 1,000L of seawater from a shipping incident.
Mobilised Wynns, and they brought a vacuum dehydration/fullers' earth treatment plant and kidney looped the whole system. RE-additised the oil with gearbox treatment - when I queried, they showed me same additive, just less diluent in the gearbox versus the hydraulic additives.
Then, with foot in the door, they brought in the one armed bandit and wanted to do a grease "shootout" in front of the purchasing people...then cried foul when I brought out the $400/tub moly/graphite/teflon/PAG rolling press grease.
Funny, even with a full shelf of them at the parts store, it's like their products are invisible to me.
