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 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.

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.
