Not a fuel expert, but I knokw that Sunoco in Canada uses up to 10% ethanol. this is known to damage fuel systems. The white deposits might be aluminum disolved from the fuel system?

The Ontario Government will likely legislate 5% Ethanol soon, going on to 10% in 2007. Anything that we can do for that ??
I thought that Sunoco 94 was the best fuel to buy here ??? Most other dealer seem to have 91 as the highest, any suggestion for the bestOntario fuel ?

Yes...I know all about race fuel testing, too. Isn't that annoying ?

Well, as I said in my post, I am no expert, but there is a sticker on the pump that says the fuel may contain up to 10% ethanol. I am absolutely certain I read the sticker correctly.

The 'reagent' tests look for other stuff...the only ethanol-related test is the dielectric test.

1. Can you tell me what rule book you are using? It makes a difference, and also Dave is from Canada and they may have different rules.
2. SCCA rules allow DC of +15 for SS, T, IT, SRF, and Olds SR running as CSR. All other 4 cycle engines must be 0 max.
3. One of the purposes of race fuel is to be guaranteed that reading of 0 max. I find it hard to believe that Sunoco race fuel would have any alchy in it at all. Sunoco pump gas (including 94) is another story. Put another way, if Sunoco race fuel has alchy in it, it would be worthless in classes that require DC of 0 max.

Oh wait. Nevermind. I see the conversation started out talking about Sunoco race fuels, but looks like it may have turn to pump fuels. That would explain the discrepancy.

Mea culpa...I read the label on the pump right, but failed to read the thread correctly. I was thinking it was another thread about pump 94 in Canada, not race gas. Oops!
