Now Mobil1 & Shell have truck-SUV specific oils. Clever to target that audience. I've always thought that if you wanted more performance out of an oil, you got the "Extended Performance" products from Mobil or Castrol Edge, or maybe went to Pennzoil's Ultra oil, or just starting using Amsoil. This will at least steer consumers towards products that help with towing & hauling heat better.
Mobil1 Truck & SUV oil is not dexos1 Gen2, yet will work for any gas non-GM truck engine anyway. They claim a "10% boost in an additive that helps prevent deposit formation and protects against wear", which I guess could be boron. Not sure. A VOA or UOA later might reveal a difference compared to the usual levels of boron used in Mobil1 silver bottle and others.
Saw "Shell Rotella Gas Truck" (SRGT) 5w30 at Walmart today. After reading the Shell Q&A, I guess the only difference is that the SRGT has "more antioxidants" for those "larger vehicle engines", as Shell says, compared to Pennzoil synthetics(?). I never realized "larger" engines need more antioxidants that smaller engines. Maybe just a poor choice of wording in their fluff marketing Q&A exercise. ...
The new Rotella is dexos1 Gen2, notably.
They also claim on the jug that its "All Mileage" which could I assume mean it has some extra seal conditioners like High Mileage oils have. Again, not clear on what they are doing exactly.
