It was my understand that shell is the only company with premium fuel @ 0% ethanol (only in there 91 though) This was a hot topic for Z32 guys because we didn't want anything in there to damage our FI systems.....
If what 6MT says is true, I will be very disappointed in our government, but this down;t surprise me I am disappointed on a daily basis
should also note in my Z cars I have only been using shell 91 for past 5 seasons (last 2 I had with z32, and the past 3 with my z34 I have had no problems with either car!
