But it is unknown how long they will keep the price the same. Looks to be a temporary situation.

I spoke to a lady at Imperial Oil and she read off an email to me that she received on the subject. It seems all premium gasses will be forced by the Government into blending ethanol.

I'm for saving the environment but does that mean that the new 91 at Esso is less powerful than the old 91?

Sounds like they know new 91 really = old 89.

Shell is as follows
87 = 10% ethanol
89 = 5% ethanol
91 = 0% ethanol

Stick to Shell Who knows how long Shell can go without using ethanol in their premium.

In response to issues on the 3.2 but really applicable for any Audi/VW engine (or really any engine!)

Thanks Tanner. I avoid and will continue to avoid Esso gas whenever possible.

allows the 93 octane program to produce more power than 91 (ethanol enhanced or not), but just results in poorer fuel economy.

Even if it had it would still be 91 octane. Octane rating remains the same. Expect a reduction in fuel economy with ethanol - whether you see it or not depends on how much is in it. Since their sticker at the pump says up to 10% ethanol its not enough to noticeably affect fuel economy. BTW Sunoco has had ethanol in all its grades for many years now.
