Should we leave MTBE in gasoline or remove it?

Im glad they started leaving it out. It does harm to the newer style aluminum engines. Something alot of people dont know is South Carolina put a pause on the clean air act in the mid 90's and monitored the ozone over and around south carolina for two years. The outcome was automotive exhaust does not have ANY effect on ozone...so you can go to South Carolina now and you will not find emission tests, because they is no need for any.
