Is the new 821 XL Permatran a synthetic hydraulic oil? Is it really any better than NAPA's best (listed as equal to Permatran on their jug) and adding some Lucas booster?

Google is your friend. Check it out and tell us what you learned... ;>) Dutchy
depends on the end use and what you consider good and what you consider cheap junk. Any triple 3 fluid is basically junk.

Amsoil ATH will drop 20 to 50 deg F off the hydro operating temp vs. permatran.
Cooler temps gives hoses, seals and gaskets much longer and happier lives
Is there any specific data on this?
I would suggest that the front axle oil be changed out to a gear lube such as 75w90 or similar at the 50 hour service. Typically the front axle would come with hydraulic lube from the factory, less chance of a mix-up during the factory build, with the recommendation of a gear lube being installed after break-in. You don't want a thin lube in your 4x4 front axle while digging, pushing or transporting heavy loads etc. Dutchy
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....Changing hydraulic or front axle oils at 50 hours is a complete waste of oil and money.
