A couple of weeks ago my exhaust started to smell.It is the worst when i start it. It smells like some sort of chemical. Not eggs and not sweet. It is not really offensive but it is noticeable with the top down. Could it be that i went from 87 fuel with ethanol to 91 pure ? I also ran some of the cleaner through a while ago. the car has been on the good gas for a while before the smell started.
