This forum and several other sources have praised Chevron Supreme oil performance. I want to run 5w-30 and have not been able to locate any at the big auto parts retailers (Auto Zone, Pep Boys, O'Reilly's etc.), Walmart, Sams, and others. I've searched the net and could not find any. I went to a large Chevron station and they only had 5 quarts. When I asked them if they had any more in the back they said no. Has anyone on this planet (or any other planet for that matter) been able to find Chevron Supreme 5w-30? Sometimes I think it would be easier to find the Loch Ness monster.
