Same goes for pre 90's fuel lines.

Only V91 for me.

 

Shell 91


However I have read that old petro stations without 94. There 91 is ethanol free as well. I've never confirmed it myself other than seeing it mentioned in a few spots online.

So if I don't use shell I'll grab some 91 at those older stations. Some exist.

 

Petrocan 94

 

Shell V Power for mine. All of 'em.

 

Shell V Power or Costco.

Is Costco always sell Shell gas?

 

Only Shell 91 for the 912. Petro 94 or Esso 93 for the Cayenne and 911 for 6 years now without any issues. Older cars - I understand, but I am confident Porsche engineers are aware of the Ethanol contrent in NA gasoline and design new cars with that in mind.

 

Shell

 

Shell 91, even the Porsche dealer recommend shell to me. Was told their track team use shell as well.

Good luck!

Chevron 94 has no ethanol. I'm sure there are others.

 

Esso 91 in both my 87 Carrera 3.2 and 2012 GTS. Never had a problem.

 

Shell V power 91 for all Porsche and PetroCan 91 for DD

 

Shell V91 always. Never at the sign of the double cross: Esso = Exxon.

 

CTC 91 for me.
There isn't any ethanol so I can use it for all the toys as well.
It's 13 cents more than regular. Other than Costco, no one can touch the price.
