Try some different brand fuels. On my DD that has a cat-ectomy some brands stink more than others. BP being the worst of them
I don't run catcons on my Cutlass with a LY6, don't notice any smell even with the top down.
Way I see it hope some treehugger in a Prius (or even better, a coal-powered Chevy Volt) gets stuck behind me and chokes on the fumes they are responsible for creating.
