Costco 91 (Shell V ~ no ethanol).

 

shell 91

 

The closest gas station after the light comes on. Usually Perto Canada or Canadian Tire.

 

Shell on the 911s,Esso in everything else.

 

Thankfully I have an Esso station close by that only carries ethanol-free gas (all grades). I spoke with someone at the station on the subject and apparently Esso allows a few stations on the province to sell ethanol free. I use it in my car, wife's vehicle, and boat.

Once in a while I'll switch to Petro-Canada 94 (especially for track days) but haven't really noticed a significant difference.

 

Petro 94 for the 911. For my other cars, Shell 91.

 

Live in B.C. Use Chevron 94 in the 3 Porsches year round. In Winter use Chevron 94 in the S5 but in Summer Petro Can 91 or Chevron 91. Audi dealer advises the need for the higher octane in the winter as apparently there are some issues with lower octanes in the winter.

 

Chevron 94. Both cars year round. No C2H5OH.

 

Shell 91. All others (Petro 94, Esso 93) cause misfire codes. I guess I have a sensitive one...

 

Only ever used PetroCanada 94.

 

I used to use petrocan 94. Switched to shell 91 to avoid ethanol. I notice zero change in performance. I decided to just avoid ethanol. I'll use the others if no shell available.

 

Chevron 94. All cars, all the time.

 

Only use PetroCan 94 based on recommendation from Porsche factory trained mechanic.

She'll V power, it's the only gas in Canada I know of that has no ethanol. Older injectors were not designed for 10% ethanol at least as far as I've read
