Well, we are all allowed our own opinion of course... The waste of oil/money by doing a first change at 50hrs??? I can't disagree more, my opinion of course. For sure the lube isn't broken down, but.....it's contaminated quite severely with initial break-in metal particles. Not a good idea to have those floating around and through expensive pumps/gears, if I might say so. End of argument, no other opinion allowed, well, unless its in a leased machine and its going to be returned for a new unit soon. Poor pity the next owner....
Disclaimer here. I sell AMSOIL in my spare time and currently, AMSOIL has a promotion for free shipping (until the end of May)if the order is over $100. I'm in Canada so I'm not quite sure what the USA offer is, but here's a link if anyone is interested.
Synthetic Tractor Hydraulic/Transmission Oil SAE 5W-3 ATH - AMSOIL
It isn't the easiest lube to sell due to the initial cost, but once a customer installs it and sees the difference during extreme temps (especially cold) they couldn't be happier, my experience. Dutchy
