    Hi Guys,

    Wondering if there are strong Pros/Cons to using Ethanol gas in the last of the air cooled versions?

    I’ve read of deposits accumulating on the valves over time, fuel system plastics degradation and mileage issues.

    Shell 91 was supposed to be ethanol free in Ontario but that too seems to be up for debate lately.

    Hi Douglas,

    I have it in writing from Shell Canada that there is zero Ethanol in their V-Power Gasoline. I think some of the confusion is because some US States require oil companies to add a certain percentage of Ethanol in their gasoline, so Shell is forced to add ethanol to V-Power in those States.

    A couple of years ago my Porsche specialist recommended that I avoid Ethanol if possible for my 1972 911 as he had seen problems with poor running, poor mileage and deterioration of seals in the early cars. I had been using Sunoco Ultra-94 but switched to Shell V-Power and I did notice a slight improvement in my gas mileage and it seemed that the car did run better, especially at the track during DE sessions.
