Never said Rotella Gas Truck wasn't stout. I was just asking what makes someone think that M1 Truck & SUV isn't, or at least isn't as good somehow.
Typically, I see higher flash point combined with lower pour point for Mobil 1's formulations with higher PAO content. Again, yes, I know RGT is good, too. I currently have it in my two Jeeps and my 3.5 Ecoboost is just starting a run with it. I'm just not seeing it as superior to the same weight in a Mobil 1 product. We'll see, though. I've had several UOA's with Mobil 1 EP and AP and will do one with RGT when it hits around 7500-8000 miles.
