Like the title say. Does the 955 957 pretty much the cayennes' line up support E85? I saw some tuner support E85 and with a lot of the station popping up around the city. I'm wondering if we could just fill up our cayenne with E85 and it would be ok to run with it or do we have to do modifications to fully support it. From my search on the injectors it seem they support E85 but not sure about all the other fuelling system.

 

We have plenty of E85 here and I stay as far away from it as possible. Our Cayenne's require hi-octane Premium gas so I shy away from anything that adds anything to the gas. I've not seen a Cayenne with an E85 badge.

 

E85 is a different type of fuel with different burn characteristics. I would stay away from E85 on your 955 for numerous reasons.
