Since when? I've switched to Shell 93 a couple years ago so I'm ootl.
Does Chev 94 advertise how much ethanol content is in it?

I wonder if it was their counter in order to compete with Shell 93..

The change was pretty recent. I think it was done within the last 2-3months.

FAQS ABOUT THE ETHANOL ANNOUNCEMENT
JUNE 23, 2023
As per provincial regulations, premium fuel will not be Ethanol free anymore. You might be wondering how this will affect you, so please see below for some answers to help solve any confusion.


About the Announcement
Who does it affect? It will affect anyone who purchases premium fuel as regular and midgrade fuel already contains up to 10% ethanol.

What changed? Due to provincial regulations, all fuel, including premium, will have up to 10% ethanol in it.

Where does this affect? All gas bars, including Bulk Fuel Delivery in BC (including Co-op).

When will it change? Affecting all deliveries mid-July.

Why? Ethanol contains slightly less energy, but burns more efficiently, so it releases fewer emissions into the environment.
I think I first learned about it in late August when someone in a Whatsapp chat group mentioned that he doesn't see the "no ethanol" sticker on the Chevron 94 pump anymore.

I figured you might need to join that group (or have fb in the first place) to see the link, so here's a screenshot:

tl;dr

Chevron 94 supposedly now has up to 10% ethanol in the lower mainland pumps.
Esso also offers 93 octane with up to 10% ethanol.

The same guy that's been doing these thorough fuel tests will do another test with the updated fuel formulas, and also include Shell 92 from the WA.

He started a gofundme to cover the costs for fuel and dyno. Extra money raised will be donated to BC Children's hospital.

Video is out now... well several weeks ago. But I just noticed now:

I ran a tank of the Esso-Mobil 93 in my Shxtbox, and came away pretty impressed. Prior to the mandatory ethanol blend requirements, my Shxtbox hated the (non-blended?) Esso-Mobil 91 -- the engine always runs coarse and unwilling to rev, so I rarely fill up at Esso / Mobil.

But now their 93 gas feels subjectively pretty similar to Chevron 94 -- engine smoothness, throttle response, and willingness to rev are all still a little inferior to Shell 93. But compared to before, it is actually a pretty big improvement, and I wouldn't mind running my Shxtbox on it now.

Incidentally, it seems to sell for 29¢/L more than regular (87) octane gas, compared to 32¢/L over regular with Shell V-Power 93. So at least I can sort of justify the slight performance loss lol~

What car is said Shxtbox?

I personally haven't noticed but I think here in the GTA they have 93 at Esso/Mobile. I'll take a look next time I'm there for a fill out and may try out a tank of it if/when available.

Traum 12-17-2023 01:23 PM

This is the Shxtbox with its 100hp of fury lol~

https://scontent.fyvr3-1.fna.fbcdn.n...kQ&oe=65A6F764

But before you think I'm wasting that premium 93 fuel on a pleb car, I can assure you that I wasted good $$$ to ECU tune it to run on (US) 91 octane gas, so that it is actually benefiting from the high octane gas lol~

Prior to its recent introduction in Metro Vancouver, I believe the GTA was the only place in Canada to have 93 gas from Esso Mobil.

That’s an epic lean. You show that lovebox what’s what

bcrdukes 12-17-2023 02:44 PM

Wow. What have you done to your Mazda 2?

My wife's Yaris is pretty fun to drive. I remember heading back toward the Swartz Bay Ferry Terminal and got busted going 120km/h in a 20km/h zone. Went so fast, didn't even know it. :pokerface:

The car is only very lightly modded.

- ECU tune for (US) 91 gas
- polyurethane and RTV-stiffened engine mounts
- (front) camber bolts
- Konig wheel + 205 tires

Because the car is still on stock suspension, its get wobbly if I try and ask it to do too much. But it is a ton of fun to bomb around town in, and having 100hp means I can WOT and beat the shxt out of it and it is still dead slow LOL~

I think your wife's Yaris has 5 - 10 more hp than my 2. At Mission Raceway, if I have a good exit coming out of Turn 9 (the final turn before the straightaway), I can typically get close to 140km/h before I need to hit the brakes LOL~

(Most other cars can probably reach 160 - 180+)
