That would be excellent!

Still using 100LL in the protege since I can get it cheap. On Husky 94 I used to get ping over 24psi of boost but could try Chevron to see how it compares.

It was all people from BC talking about it but cant remember where I read it. By the sounds of it, I would't be too happy about it.

Hopefully, local shops can do a comparison between Chevron and Husky.

Petro is garbage.

That is correct. Owners of tuned GTR's were getting better results crossing the border for US Chevron 91 than BC Chevron 94. I would like to see some evidence that this gas is any good as I have a hunch Shell 91 will probably still be better for most people.

Sucks if that’s the case, non ethanol 94 would be really nice.
I can confirm that husky 94 is superior to shell 91. A couple years ago the husky 94 was getting hard to find so I filled up on shell 91, it pings even at moderate boost for me. I had to retune and pull timing earlier.

Never tried Petro 94, is it the same or better than husky?

Yeah but Husky 94 has ethanol in it too. Not sure on Shell 91 as I haven't filled there in awhile.

She'll V-Power certifiably has zero ethanol (in this market).

I'm also looking forward to a dedicated pump for Chevron-94!

I asked him about that last year as I have a Subaru that used to be tuned to Husky 94 and I go pretty deep into BC for skiing:
In a pinch, PetroCan94 can be used in place of Husky94. Chevron 94 isn't BC is recommended as I have seen results worse than Shell 91.

Based on that, and the fact that Husky is trying to divest all of their downstream (retail) segment, I went with a Shell 91 tune. I had bad results from the Sicamous Chevron 94 in my Z as well (Husky 94 tuned), all the same settings with a Profec and it would overboost and ping. IMO its bad gasoline.

There's also the greater latent heat of vaporization for ethanol than gasoline which afaik isn't included in the octane rating. So you'll have higher effective octane in an ethanol blended fuel than a straight gasoline because the charge will be cooler. I'm firmly in the ethanol gas camp when your goal is to make power. Mileage on the other hand...

I haven’t had good experiences with Chevron 94 in BC, will stick to Shell 91 for my car I think.

Any of you note what the price differential between 87 and 94 is at chevron?

Thanks for the info. I was hoping that Chevron 94 would be a replacement for Husky 94, because of reasons that you've mentioned. Seems like Shell 91 would be the next best thing if Husky 94 becomes extinct.

Agreed on the ethanol blended pump gas. Wish that we had more e85 stations in town, but I don't know if I would daily a car running it. Getting 200-250km per tank would get old fast.

When I filled up last Friday, 87 octane was $0.93 and 94 was $1.17.

Their spread between 87 and 94 is less than Shells spread between 87 and 91.

Seriously, fuck Shell. I don't care how good their 91 is.
