I feel like an outlier here because I never was able to tell a difference in daily driving between Shell/Esso/Chevron 91, which I used interchangeably. But I admit I did always have a perception that Shell was the highest "quality", whatever that means.

My current vehicle only needs 87 and I enjoy that it's cheaper lol.

quick update -- straight from the horse's mouth:

Funny you mention Petro 91 because that is a gas station/brand I almost never go to. I've never had good results with their gas and my cars always run like crap after filling up on Petro 91. Most dyno threads always seem to be a comparison between Shell and Chevron, never Esso, Petro, Husky/Mohawk, or Costco. :concentrate:

but Kirkland Signature bro

Funny you say that because Costco gas uses Top Tier additives, and that seems like it uses a Shell base. Their 91 hasn't caused any issues on my GTI.

I might be the only one who thinks this but the best thing about Petro Can is you can tap your credit card on the pump, no need to insert chip and enter PIN.

Only saying petro because that's what we sell, so that's what goes in the R8. Have not really noticed a difference in types of gas from selling ESSO, Tempo, Shell, and Petrocan. The only problem we had was with Shell when they changed the formula and it caused problems with gauges. That was across North America.

Petro is considered top tear, Husky is not. Husky is not building any new gas stations and is now also an ESSO dealer. Basically a middle man between corporate ESSO and the gas station.

We need someone in the gas industry to really explain what's going on.

Shell, Husky, and Esso have mobile apps that allow the purchase to be done entirely on your phone. All you gotta do is pretty the physical octane type button on the pump, and pick up the fuel gun afterwards.

With Esso 91 I got significantly better mileage out of my wifes old 97 Prelude. The price jump from 87 to 91 varies wildly all over town though so idk how it works out in terms of actual $/km.

Well I guess I'll be switching to Chevron 94 after 10 years of Shell.
Airmiles will still be good for my Safeway runs.

I'm interested to see if I'll be able to feel a difference however my car isn't tuned; only bolt ons. Probably not on a day to day basis but 40HP difference on an S4 would be quite noticeable on the road, no?

Question for those of you in the know; if I'm pumping 91 from a nozzle that's also used for 87/89... am I pumping residual regular in the line from the last person to fill up before 91 kicks in or does the fuel go back into their respective tanks after stopping? I think I've only been to one or two Shells in town that had a dedicated 91 nozzle.

Is anyone else switching from Shell to Chevron?

I've started making chevron 94 my regular choice since the shell near me always gouges high traffic times at the pump by like 10-15c. Milage in the e36 actually seems a bit better with shell, but the car feels better with chevron as of the last year or so.

i got in trouble from the 70 year old gas jock at the edgemont chevron for using 91 in the 996

he walked past , didn't even look over his shoulder - just told me "you're using the wrong stuff"

:pokerface:

:alone:

I mean, was he wrong?:lawl:

i mean - he hurt my feelings :okay:

The fuel from the previous fill up stays in the hose. So if you are filling up with 91 and the last person bought 87, you'll have at least the entire hose's worth of 87 gas, if not a tad more.

Eons ago, Shell used to have a separate nozzle for V-Power, but I don't think I have seen separate setup like that for a very, very long time. I think Chevron is the only one that does it now.

yes been putting in shell since not being able to fuel from costco bellingham
will scope out some esso pumps if they're really also top tier
port injected higher compression still gets chevron 94

I have used Chevron 94 on any vehicle that was even remotely considered "performance" for as long as I can remember and I'll always seek out a Chevron even for 87. Not sure where the loyalty came from but thanks to these videos my undying zero research driven love is now justified. Lol!

Loving those new app; now how to fill my car without touching the handle...

There's an app that will work the handle for you?:woot2:

It's called full service. :troll:

When I was in Alberta, I used Petro-Canada 94 in my Camaro and it was fine. Curious how that would do against Chevron 94.Petro-Canada dropped out of Top Tier a while ago. No idea why, some have rumoured that they just don't want to pay the fee.

This popped up in my YT feed after watching Vancity Audi.

Guy on the island compares Chev 94 winter blend against Shell 91 summer blend. Shell wins.

Is it possible in the GVRD, in November, Shell was moving winter blend while Chevron was still clearing out their inventory of summer fuel?

For my car (2018 Civic Si), Chevron 94 runs better than Shell 91.
I run an E10 blend with a fairly aggressive OTS tune (24.5 psi + ~30 deg. adv. timing) and monitor stuff daily.

Even blended with ethanol, my car detects minor knock on Shell 91 while my car warms up; it never does that on Chevron 94. That knock goes away once warm though.

Here's how I rank gas in the lower mainland for my car (determined by knock readings):
Chevron 94 E10 blend > Shell 91 E10 blend > Washington Shell 92 > Co-op E10 blend > Chevron 94 > Shell 91 > Costco 91 >> Petro 91 (car hated this stuff, possibly bad gas)

As already stated, Chevron 94 can be inconsistent. It seems like 1/5 tanks isn't as knock resistant as the others.

What blend should I run in my 2006 camry?

Chevron 94 with octane boosters
