Subject: **RE: Ethanol in Shell v-power 91?

Shell V-Power 91 octane premium gasoline does not contain ethanol all over Canada.

Ethanol is a real problem in marine applications. With the USEPA going to 15% Ethanol, it's why a waiver was applied for and granted. I'm not sure how effective it will be. Most "premium" fuel does not have ethanol, and even some regular across the country does not have ethanol. Ethanol is blended not at the refinery but further along in the process, so at a distributor. The blend must be 5% across the entire fuel for Canada at a max of 10%, so most of the Ethanol is mixed in at 10% in urban centres in the regular fuel. This gives enough of a blend to make up the 5% total across the country.
(The 5% you see in the mid grade is just a product of the 10% in 87octane, 0% in 91 octane, blended at the pump gives 5% in the 89 octane)

This doesn't make sense to me. I thought the purpose of the ethanol was to improve the octane rating so the 91 rated gas should have more ethanol in it.
Of course I spent the first 30 years of my life breathing in lead fumes so I ain't too bright.
FYI for some of you, They used to create higher octane gas by adding a compound called tetraethyl lead. I think they added 1 -4 grams per gallon and in a city of Toronto you couldn't avoid getting contaminated. (Gee I wonder why there is so much Alzheimers and dementiannin our old folks) If you see gas pumps in old movies and see the word "Ethyl" then you know that was the good stuff. The ethyl groups would break away from the lead and react with the broken gas molecules to prevent an "explosion" and produce a smooth burn. The lead helped cushion the valves and rings because it is such a soft metal.

The reason the US had to go to 15% was not because the EPA really wanted to increase the amount by % in the fuel, but because they had been mandated to increase the volume of Ethanol used. E85 has not taken off as expected (though more in the US than Canada). Cars are becoming more efficient so at 10% they had hit a blendwall and could not add any more volume without increasing the ratio.

Manufacturers of engines are not particularly happy with the decision. Farmers and alcohol producers sure.

E15 is not coming anytime soon.

Furthermore, the US has recently eliminated the ethanol subsidy that previously made it economically worthwhile to use it, and the auto manufacturers have filed a lawsuit because non-flex-fuel vehicles have not been designed to comply with emission standards with any more than 10% ethanol. The official EPA Federal Test Procedure is run on 100% gasoline ...
