Re: Vaporizing gas fix

I am wondering where in the production stage ethanol is introduced. According to wiki-answers, almost all gas regardless of grade contains ethanol--but can be region specific and must be labeled. Supposedly there are two tanks in a station -- one for 87 and one for 93 with the 89 being a blend of the two.

We had an incident here a couple of years ago where diesel was accidentally introduced into the gasoline at the tank farm because of an improperly set valve. Hundreds of cars either quit, had major damage after filling up one morning, or the fortunate ones were those who heard of the problem in time and only had to have their tanks removed and emptied. Cost the stations and supply farm a very large bundle since they picked up the tab for repairs.

Interesting part was that this was not confined to one or two stations. According to the paper, it turns out in this area about ALL the stations regardless of brand affiliation get their gas from the same supply tanks at a central depot. The differentiation between brands occurs when gas is actually loaded on the delivery truck and the brand specific additives are then included. In this case, those stations that had a night delivery were the ones affected the next morning.

Would think this might be more the norm in todays world so other areas might be the same. If the ethanol is blended in at the refinery all brands then should be similar.
