These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I don�t want to jinx myself. I use regular fuel in my carb�d mustang, 2 stroke outboards, lawn tractor, generator, chainsaw, etc. Etc. Never any issue.....luckily. Regular 87 octane in Canada has ethanol. 91 Octane at the retailers I frequent does not ethanol. 93 octane, has ethanol. So, what should I use in 996? 91 no ethanol or 93 with ethanol?

POST 2Original post

E5 and E10 has been used in Europe for a long time now, (mainly since 2000), so these engines are ready for working with them without problem. I think that it is more important to use the higher octane possible (93 in this case)

POST 4Original post

Pretty much all fuel where I live (Chicago) can contain up to 10% ethanol. So there�s 8 million people using that fuel blend. If it were me, I�d pick the 91 without ethanol, but I�m guessing it doesn�t matter much.

POST 5Original post

I don't think I have that choice in New York. At least I've never seen it.

I'm in Albany NY and we have that choice here a many stations.

POST 8Original post

Do you know which brands? I usually buy BP or Chevron and haven't seen anything but 93 with ethanol.

POST 9 / ORIGINAL POSTEROriginal post

So, since I'm in Canada (Toronto), choice is limited between Esso, Ultramar, Husky, Shell, PetroCanada and Costco. Strangely, the only trucks I ever see delivering fuel at any of these stations is Seaboard Transport. The only fuel depot that I am aware of is in north Toronto. Ultramar and Husky I consider to be second rate gas and usually have less expensive pricing. As a rule, I get gas at Costco. Closest station too me and is always about 40 cents cheaper per gallon (10 cents /litre). Since there is only one depot and only one fuel transporter is the greater Toronto area, am I to assume that all fuel is actually the same? It surprises me that in doing internet searches, I have yet to see any consistent comments about the ethanol content at these gas stations. So, I guess I will fill up at Esso with their 93 octane and ethanol and focus on the octane content rather than the ethanol issue. Thoughts?

POST 10Original post

Locally, Shell 91 VPower + is the only ethanol free gas. There is a noticeable drop in power for my car between Esso 93 and Shell 91. I don't notice an improvement in gas mileage on the 91.

POST 11Original post

Gentlemen, This has been discussed many times over the years over on bobistheoilguy.com, where lots of petrochemical geniuses lurk and post. Short story: Ethanol robs your engine of power (even ones made for it). Always choose ethanol free if you can. Don't know about Canada, never been there, but here in the great country of Texas, my go-to choice is Chevron premium. I've only seen Ethanol free fuel at a few places for over $4 a gallon, so I don't go there.

POST 12Original post

You can check in with: https://www.pure-gas.org/ That site will help you locate all the ethanol free gas stations in the country. I have their app for my iPhone as well.

Confused. 93 lower power or 91? I am expecting 93 more power?

POST 14Original post

Quotes source post: 15655189

More power on 93. Or the Petrocan 94. It may just be between my ears; I haven't dynoed it.

POST 15Original post

Quotes source post: 15655189

According to the guys over on bobistheoilguy.com, always choose the no-ethanol blend, your engine/fuel system will love you for it!

I use Stewarts 91 ethanol free. It is a rebranded Sunoco. Lots of the shops don't even rebrand it and have Sunoco signs up.
