The general consensus is this:
1) Shell (SOPUS - Pennzoil, Quaker State) has a good reputation, and has for many years.
2) Shell Rotella Gas Truck (RGT) is a slightly thicker oil than most others in that grade, which helps fight possible fuel dilution when towing or hauling.
3) Their claim of better anti-oxidants may use intellectual property from Infineum, their additive company they co-own with Mobil, so expect advanced anti-ox.
4) It's dexos1 Gen2 certication means it meets the highest domestic oil specs. (Only tougher specs are BMW LL-01FE in the HTHS 3.0 class you use.)
I'd recommend RGT to anyone, although I tend to favor Mobil1 Extended Performance, Mobil1 Annual Protection, or Castrol gold jug Extended upper tier oils if you are looking for something better.
Others on here like to whine about "marketing". Just look at the facts, I say.
