Best gas

I'm with you. I run superstore gas all the time in all our vehicles, never noticed any difference.

There are I think only 4-5 type of stock offered in Alberta.

Chances you get Shell 91 without additive from COOP or Superstore is probably 1 in 4 or 5.

Someone mentioned Centex as one to avoid. Any known issues? They are dirt cheap sometimes... and it really makes a difference when it's $1.25 vs $1.35 at Coop or Shell (premium). And I haven't noticed any differences, then again, I am not a racer nor do I have any sensors to tell me whats up

A guy on his evo x got tuned about 3 months ago here in calgary and he had shell 91 in the car. His car was getting a good amount of knock counts and power wasnt so good. He then tried husky 94 and knock went down and power went up due to all the variables.

Note: im not saying husky 94 is better, just posting what I heard from that guy.

I use esso on my beater just because its really close to my house. When I do use shell 91 I get a bit better mileage. Coop and costco made my old car run like shit. The evo only gets 94 now

I remember some horseshit was floating around in a thread a while back where someone tried to claim centex "watered down" their gas

I don't see why you would avoid them. As long as it isn't an ethanol blend you are good to go, and even if it is who really cares, I'm just picky and don't want poor mileage and messed up fuel trims.

Petro also has 94.

shell vpower gives more milage than others.

I drive a Ls1 Camaro and was running Treo 93 premium.Treo was down doing reno's and tank replacement and Centrex was selling premium at regular gas prices that night. I only put in a quarter tank to fill and butt dyno felt an increase in response and acceleration. So dunno about those rumours about Centrex.

I've had no issues with Costco premium gas.

BMW recommends only Shell be used in their cars.

I've always used shell because it's close to my house and more importantly lots of airmiles haha.

I run this and Husky 94 in my car and it loves it. Shell 91 gets just a wee bit of knock with my tune, but I have buddies who swear by it.

There are so many variables when it comes to gas and its effect on vehicles.

If you have a very high compression engine and are running 91, of course you will notice a performance degradation as the engine is intended to run fuel that resists combustion as possible.

If your bike is intended to run 89 (stock), putting 91 or 94 in it might actually REDUCE performance.

The octane thread reminded me of this. Curious if people still think Shell is the best or if the go elsewhere.

I religiously fill up at Shell but beginning to think I should start using Coop gas since all grades come apparently ethanol free.

[Twin_Cam_Turbo]

Still using Shell 91 and CO-OP diesel.

[killramos]

Mercedes always fill at Shell.

Jeep gets filled wherever is convenient, I doubt it’s minivan engine cares.

[ExtraSlow]

I still fill up at whatever station is handy or cheap. Still don't think it makes a difference.

Made the switch to Co-Op for almost 5-6 years ago because they keep closing Shell stations that's convenient to me.

Mobil for the PC Points, my beastly Suburban don't care much about quality of gasoline as best as I can tell.

Yea my 'HondaSpeed' Civic or your 'NISMO' Fit wont care really, unless youre banging off the rev limiters on a track..... haha.

I did notice it on the bikes though - different gas from different stations on the same day, same roads.
