Zyonara91

+1 on this. I ONLY use Shell 91, why? No ethanol. Ultramar and Canadian Tire say they do not use ethanol, but I don't know. Canadian Tire 91 has ethanol, I'm sure of it because I've seen that "may contain 10% ethanol" sticker on the pumps. For Ultramar, their 91 does not have ethanol but their additive package is no where near Shells.

Costco, hit and miss, since they get their gas from Shell and or Esso (Or was it Petro) anyways, it's a hit and miss. This one time I put in Costco gas and damn, the Z was pissed, she wasn't having it. . . Strange because my other car that only takes 91 is hapy with Costco gas. Hm.

Shell is the go to, if I cannot find once when I travel, then I go with Esso 91.
