Octane Boost

[clickman]

Chevron 94 in BC doesn't. At least, they say it doesn't.

From Government of Ontario Website:

"The Ministry of the Environment and Climate Change regulates the amount of ethanol found in gas sold in Ontario.
Gas companies, suppliers and sellers must include a minimum amount of ethanol in gasoline they distribute and/or sell.

By law, you must:
-maintain at least an annual average of 5% ethanol in the gas at all your facilities combined
-submit a compliance report to the government every year
-ensure that ethanol-blended fuel meets specific quality standards set out in regulations"
**********************
I guess the key part of this is in the wording. Companies must put more ethanol in their lower brand and thereby can put less or none in their higher octane brands. As longs as they have 5% ethanol across the board - they just put 10% in the lower levels and that covers them.

That's correct, they bumped up the ethanol in their 87 and 89 to be able to have their 91 ethanol free, I believe they are .....87- 15% ethanol, and 89-10% and 91- 0%

FAQs — Questions, Answers, Gasoline Products — Petro-Canada
From the Petro Can website for instance.... one of the questions is:

Does Ultra 94 contain ethanol? Does Petro-Canada still offer an ethanol-free gasoline?
Ultra 94 contains ethanol. Due to the fact that various fuel grades are blended at the point of sale, most grades of Petro-Canada fuel may now contain up to 10% ethanol. This represents a change from the previous state, where premium fuel was ethanol-free at Petro-Canada.

***I know their premium fuel used to be ethanol free as well, but that has also changed in the last little while, hence 'the last sentence in their answer'
I think you'll see the rest of them follow suit if they haven't already. Even in Europe E05 is changing to E10 despite the number of people who are against
it. Its like back in the early 80's when you used to be able to buy regular leaded and unleaded fuel... remember all the fuss everyone made out of the additives you had to put into vehicles that used leaded fuel... and those cars are still driving around today

I was wrong about the percentage, this is my local shell

When switching fuels, or adding octane booster, the ECU needs a :handover" or a hard reset to reset the adaptive... I have seen guys dump in higher octane and the engine make LESS power, because of the adaptive.

There's no silver bullet.

Well the shell.ca website used to specifically say that there is no ethanol in their V-Power fuels but if you go and look (Shell V-Power® Premium Gasoline - Canada) it doesn't say anything about no ethanol anymore, actually they don't even mention the word 'ethanol' period.

Oh well... just fill it with a reputable premium fuel and drive it like you stole it
