Yep. The petro can in crowfoot has had it for at least a month already.

any other ones near the core have this?

Kensington and 4th st/19th ave sw, are the two closest to the core.

Re: 94 octane at petro canada

I've seen the 94 everywhere I go now. Good news for those out there who are interested in moving up to 94.

I recently filled up the .:R on 94 for sh*ts and giggles. The next day, I noticed a huge difference. Normally, with a cold VR6 (or at least mine) on startup... the exhaust will warble and barble and pop. Not a good warble, barble, pop like you'd get from a Porsche with the Sport Exhaust but more like the engine is starving for air and trying to breathe. If I give it the tiniest bit of throttle on startup on 91, she'll fire up fine... but without... she coughs and spits like and angry baby. Anyhow, filled her up with 94 and the next morning (and whenever I've taken her out since) she fires up and instantly purrs like a kitten. Ok... more like a baby wookie... but either way... she sounds good. Perhaps the 94 is just compensating for an old car that is in need of a tuneup... I dunno. Just wanted to share my early experience with the 94. Whether it gets better mileage/performance I don't really care to be honest. I think I'll switch to 94 anyways in the near term until she gets a new tune.

Cheers... Rob.

Re: 94 octane at petro canada

Yup because they picked up that fourth option. This is all thanks to Petro scooping up the Canadian Portion of Sunoco Gas.

you mean its because Suncor (formely Sunoco) merged with Petro Canada, Suncor is the company name but they kept the Petro branding on retail stations

Re: 94 octane at petro canada

^this.. petro can tower downtown is now to the suncor building


i hope the petro by my house gets it soon then that would be nice i've banned petro for about a year now (they f'd up my points card/scammed) so i started using shell all the time

Re: 94 octane at petro canada

It doesn't warble, barble, pop as much because its running leaner during warm up enrichment.

Why would it run leaner?

Re: 94 octane at petro canada

Earlier in this thread I was going on and on about it. Its pretty boring but basically the engine isn't tuned for oxygenated fuels and during fuel enrichment situations like warm up when it isn't getting o2 feedback yet, and acceleration enrichment the engine will run leaner.

Re: 94 octane at petro canada

Will the base fuel trims not adapt and still be applied whilst the correction factors are applied during enrichment?

I understand the theory, but in application does it hold true?

To me it is interesting. These fuels are only 10% ethanol correct, so is the effect as drastic? I could see the applied difference as being minimal. If one thinks of the difference in efficiency, and applies that to the 10% by volume factor, than the end result should be a minimal factor.

I'm in the same boat, but my buddy with his Big turbo sr20det drift machine saw substantial changes in his knock and timing values with husky 94 compared to shell 91.

Re: 94 octane at petro canada

It gets complicated because the engine management calculates required fuel based on the the mass of air entering the engine so it knows very precisely the density of the air but it does not know the density of the fuel. The fuel is injected by volume, opening an injector a specified amount of time under a specific almost constant pressure differential. So in a closed loop system combustion is monitored by measuring oxygen content, but the problem is that even on a chipped ECU the ideal oxygen content has been tuned in conjunction with the ignition timing for a specific fuel so the fuel trims will eventually add enough fuel to get the programmed oxygen content but because the fuel is less dense you need to add even more fuel as the stoichiometric air/fuel ratio has changed. Also even if the long term fuel trim is used to calculate acceleration enrichment it will still fall short because its making a volume calculation based on an incorrect fuel density. Furthermore a lot of people seem to be under the assumption that the perfect ignition timing is the one closest to detonation, perfect ignition timing is achieved when combustion pressures peek around 10 degrees (depending on the engine) after top dead center, so the best ignition timing is often nowhere near detonation. My point is that ignition timing is directly linked to the speed of combustion and this also will change with different fuels, in turn affecting combustion efficiency (incomplete combustion) resulting in miss leading oxygen readings. So in effect if you have a turbocharged engine your not taking advantage of the higher boost you could be running due to the higher octane rating and your not injecting enough fuel and the ignition timing wont be optimized.

To me it is interesting. These fuels are only 10% ethanol correct, so is the effect as drastic? I could see the applied difference as being minimal. If one thinks of the difference in efficiency, and applies that to the 10% by volume factor, than the end result should be a minimal factor.

I agree so don't bother buying it.

Re: 94 octane at petro canada

Having read this thread, and particularly the comments by shconer, I suspect that the poorer performance I'm seeing in my M5 is real. I started using PC's 94 octane a week ago in both my bike (BMW R1200RT) and the BMW M5 (2008). The bike has never run more smoothly and I didn't notice any change in performance although I have this feeling that may just be covered by the available power with more throttle. With a 'mixed' tank in the car (normal premium plus 94 octane) things also seemed to unchanged, perhaps smoother during warmup. Yesterday I had run the tank pretty much dry so I could get a complete fill and had a great shock when I tried to accelerate sharply and it didn't. Checked this out a few times in case it was me and came to the definite conclusion that the low end accelaration was way down. Even switching to the 500 settings didn't have as much effect as usual. I guess the big question is whether the system will sort itself out - how many km does it take for the settings to adjust? All in all I think I'll be going back to regular premium for the car. May stick to the 94 for the bike just for the smoother idle and give up a few horses - more than enough for normal riding.

Re: 94 octane at petro canada

Talked with a Suncor employee at work today.

Petro Can 94 DOES NOT CONTAIN ETHANOL.

Just FYI.
