comparing it to 93 and the fact that with that being the highest available, most people will put 87 in their cars as it is the cheapest, lowering your emissions and performance. multiply that X's the number of vehicles on the road out there in Cali at any given pt in time, and you wonder why everything has a sticker that says "has been known to cause cancer in california" its not the product, its the shit-ton of smog created by the millions of cars on the roads over there.
and yeah, its unleaded... tho they have 113 leaded but i wont mess with that.
