As some of you may have known, I posted a while back in regards to contacting a Chevron tech as to whether Havoline and Chevron Supreme are identical formulations. This past week, I've been talking to a BITOG member whom works for Chevron via e-mail, and we've discussed this topic.
From what he has told me, Chevron Supreme and Havoline share the same base oil, but use different additive packs, with Havoline having the more robust additive pack. Havoline is suppose to be their higher-end oil, which makes it the one that happens to have the more robust additive pack.
In addition, he stated to me that it is illegal to market an indentical product under different brand names and charge different amounts for it. (violation of some trade act) Thus, as similar as Delvac 1 and Truck & SUV may appear, they are indeed different products.
