I've been running Esso 93 and Petro Canada 94 exclusively since I bought my ST. Both contain Ethanol.

On my most recent tank I filled up with Shell 91 which has No Ethanol. The car seems to perform better on the Shell 91. Has anyone else experienced this?

I'm curious to hear your Canadian gasoline experiences.

I've been going between Chevron 94 and 91 lately. Can't really tell a difference. I should try Shell 91 and will report back.

I've been using Esso 93 from day one. Seems to be ok

I've been using Costco 91 which gets shipped in from Edmonton to Prince George, have had good success with power and fuel economy. But every region of the country will vary depending refinery locations etc. Last summer I was able to achieve better than stock 0-60 times running Costco 91 fuel with my best time of 6.7sec and that was without MP215 installed.

In Alberta I run Petro 94 or Husky 94 both contain 10% ethanol, I feel they give me the best power performance. I have tried Shell 91 but didn't notice any better performance... well maybe slightly better fuel economy I guess. The fuel I like the most is Chevron 94 but unfortunately for me it is only available in BC. It has great performance and gives me better fuel economy than the ethanol blends.

With my Evo 4 rated for JDM 98 octane (about 95-96 for Canada), I've had the best success with shell 91 because it wasn't cut with ethanol. Will give results for the FIst when it arrives.

Remember gas from BC / Alberta is different from Ontario / Quebec and is different from the Atlantic provinces.

I have used only shell91 as stated lowest ethanol content and most detergents. Never compared so I can't comment on butt dyno. I just wish shell had 93 or 94 octane but I choose it mainly because its the highest quality I can get.

In Ontario, Husky & Shell carries 91 ethanol free (make sure the pump says so).
