HIGHEST octane at calgary gas stations

[ACS-e36]

sofar the highest ive seen is 92 at a esso. is there any higher anywhere?

[bol]

rage2 has done some fuel testing here and from his results...


#1 Mohawk/Husky 92
#2 Esso 92
#3 Shell 91


he can probably elaborate more


personally I stay away from Shell now...

[bol]

Of course there is always VP103 :P

[ACS-e36]

yeah i hear some stations are crap... and stoot out piss gas... which would thoes be?

[rage2]

If you can find exactly what octane level your car uses before detonation and at optimal ignition timing advance, use that fuel, it'll make the most power. Any lower octane and it'll retard timing, higher octane and there's less energy per stroke.

If your car's a turbo, get the highest octane possible and crank up the boost till you get detonation at optimal forced induction timing. That's how you'd get the most power.

All about experimentation!

I know this is not in town, but revelstoke has 102 octane pump fuel, damn near died when i saw that. do john deere's really have that high of compression?? lol

mohawk gas is better, nothing idles smoother or gets the engine to temp faster

Not a good idea if you own a rotary

That is cause they put alcohol or something in it. In the winter in California, they add alcohol (or something) to make the engines run hotter. That way combustion happens more completely and you get less smog. That is why they call themselves "Mother nature's gas station."

The drawback to that is you get shittier gas milage. Your milage may vary, but I noticed about a 10% loss.

If you are not driving with a customized engine, then use the fuel that is recommended by the manufacturer.

I think that it was R&T or C&D that did a test on the 6th Gen Accord V6. Using any fuel higher than the recomended 87 octane actual cause the motor to lose power. With my Av6 I get the most power using the cheap stuff.

i wish mohawk still had 94 octane.
I use to drive to 16th ave just to fill gas

[calarina]

I find that Petro Canada's 91 Octane gets me the most milage. My last tank I got 236 miles to my tank! When I normally get around 210 miles with any other gas.

*note* notice the "miles", and not "kms". Car's from California

I think I still get the best milage from esso gas. I only need 87 octane... heh...

[Roaring G60]

this is a simple problem to solve: Toluene mixed with a tank of gas. It is the main ingrediant in octane boosters, it nomial octane rating is 114! It is available @ paint stores for around $10/5 Ltrs.(better than race gas) In the turbo days of F1 the team where using 100% toluene as there fuel with boost pressure towards 5bar for qualiflying, This fuel was the only thing allowing these motors to make 1500+ hp without detonation.(note do not attempt to use toluene as your only source of fuel as that it is somewhat volitle and needs to be mixed with gas, the general consensus is no more than 10% toluene!!!!
(note the writer of the post assume's NO responsability to anyone who decides to use above mentioned products in there Car/truck/lawnmower)

You can buy a drum of 103 octane VP 103 unleaded fuel for a little more than what it would cost for Toluene.

I believe xylene can be had for cheaper than toluene, and has the same effects. Problem is with the shitty gas we get it takes a relatively high percentage of the stuff to make a real difference. Why can't we just get better gas to start with?

Because we're at high elevations here, and we (well stock cars) don't need the high octane. In vancouver, whole different story.

I heard the regular in Colorado (like 6000+ft elevation) the Regular gas is 85 octane.

You act like that was some kind of secret. I've always known Shell Gold was 91. I think you can read it right off the pumps at some stations.

Has nothing to do with misleading octane ratings...

they've had numerous additives in their gasoline that have caused problems for people

the fuel injectors in our old car were killed because of an additive in their gasoline, there was a big stink about it awhile back, only affected GM vehicles.

shell did pay for the repairs though

In my mind though, anything that's bad for one companies fuel injectors can't be good for anothers.

Just because a company advertises 91 doesn't mean it's really 91 (not shell).

whats the story with shell??
