OMG! Somebody is agreeing with me!
Gasoline is a dirty, dirty mix of thing that occur naturally and more that are added for among other reasons, regulations... This is not your father's gasoline.
MTBE is a silly fear. Oh noes, there's MTBE in my drinking water... No fear of benzene, ethyl benzene, toluene or xylene, MTBE, OH NOES! MTBE should be used as an indicator compound to prove tanks are leaking.
