Don't recall seeing any mention of folks using Schaeffer products on this Forum. Anyone using Schaeffer products in their trucks???
Specifically, is anyone using their #741 synthetic 75-90 gear lube in the GM HD series pickups with the Eaton G-80 differential? I won't use "Grape Juice" because it costs a ton from the "Stealer". Most folks I know are using Mobil 1 Synthetic 75-90 with good results. Comments??
Also trying to find out if Schaeffer make a synthetic ATF that meets Dexron III and Allison (1000 series trans) specs as an alternative to Mobil 1 or TranSynd but it does not appear they do.
May just default to Mobil 1 for the Alli, diffs and Xfer case.
