mtbe is a known carcinogen. yet, the environmentalists mandated it for california. meanwhile, the oil companies got rich from this additive.
10 years ago kgo radio host bill wattenberg (not ben) used to yell his lungs out about this issue. it causes cancer, he'd say. but no one paid any attention. meanwhile, the state's rivers, lakes and underground water are contaminated with this stuff.
finally, the state of california decided to remove this junk.
and guess what? now the oil refineries are saying they'll have too little supply and so the price of gas will go up!
Other gas stations in Woodland have signs claiming no MTBE; guess which ones I go to (when I remember that I want to avoid MTBE). I have not noticed much of a price difference.
