I'm pretty sure there's a gas station off 1936 that has 93, but there's only 1 pump that will have if. I'm not sure of the exact location, or gas station, but you can call complete customs in west Odessa and there's a guy there that knows exactly where to get it. Or you can just mix your gas like I do, better to be safe than get some bad gas. You can use torco, complete customs carries it, or you can get 105 octane gas from midland performance headquarters.
