First the smarty pants comment, we have been fed bad gas in CA for years. My mpg dropped from 20 to 17 as soon as oxygenated fuel was foisted on us. The MTBE used to oxygenate the fuel turned out to be a real mess. On topic, it would be interesting to know where this fuel was sold. I lived in San Diego County for 50 plus years. Wonder if they recycled any leaded fuel into the mix?
