I emailed Chevron to try and determine the difference between Chevron Supreme and Havoline. Here's the text:
"Mark,
I understand your comments and, no, you would not choose an oil
based on the color or the name. You choose oils based on the OEM's
viscosity recommendation and API service category. Currently, our
Havoline and Supreme line carry the latest API specification which is
SL. Additionally, one thing that is found in both Havoline and Supreme
is that they are blended with Group II base oils which is a base oil
technology developed by ChevronTexaco and licensed out to other major
oil companies. This base oil (Group II) is of a higher quality (will
oxidize slower )then engine oils made with Group I base oils.
Either one you choose, you are purchasing a quality oil based on my
comments above.
If additional assistance is needed, you may call us at 1-800-582-3835
and voice any additional concerns or doubts you may still have.

Thanks for the reply.
I understand some things have to be proprietary, but how is a person
supposed to choose between two products without any
information, just by whether he likes the name, or the color of the
bottle?

Mark,
Both the Havoline and Supreme line are different products with
their own unique additive package. Details about what makes them
different are confidential. "
Any comments, facts or opinions?
