Does anyone have experience with D-A Lube Reliant J-4 FS 5W-40? We have a couple of customers running it now and their oil analysis reports show it to be on par or better than T-6 in reguard to cumulitave wear metals, the base number does come back a little lower but the oxidation also comes back lower and it apears to have more calcium and less magnesium which I believe is a good thing.
