I've been diehard against using anything except Shell Rotella T6 in My Ram 2500 Cummins, I didn't have a issue finding T6 in Texas now I'm just outside Sturgis and can't find it anywhere! All the parts stores say they haven't seen any for over 6 months now. It seems the shortage is worse up here? I found a oil I haven't seen before Schaeffers CK4 700 SynShield® Durability Advantage Engine Oil 15W-40. Anyone use this in there Cummins? I purchased 3 gallons today, all the reviews I can find make it look like Royal Purple for Diesel. Can I trust it? I've been towing a 8500lb trailer all over the USA and just upgraded to a 10k lb 5th wheel . My travels will continue for a while. I never push the oil change past 5k-6k miles while towing. I know it's hard on the oil especially in the triple digit heat we've been experiencing . Just looking for anyone with experience with this brand, any issues they may have encountered?

Schaeffer's oil is hands down the best oil on the market. I run Schaeffer's in everything that I own!

You didn’t look on Amazon. 3-pack, gallon jugs (12 qts) is less than $100, free delivery.

Same deal from WalMart, 3-Pack, gallon jugs, free shipping less than $100

I had no idea there was a shortage of Rotella. I just bought a case on sale end of April and they even sent me a $40 rebate.

Well, the shortage announced by the OP is now 4 years old.
I sometimes check dates. Sometimes. ;)
