After my 91 canned tune is knocking on Shell 91, I switched to Chevron 94 so letsee. Though now I am hearing people have better luck with Shell 91 than Chevron 94.

Aaaaaaaanyway, I am hearing a lot of people say our gas sucks compared to US gas and that Chevron 92 in WA state is much better than even our Chevron 94. Lots of praise for Shell 91 even though my car doesn't seem to like it unless bad batch.

So my question is....WHY? Why is Canadian gas worse than US gas? Or is it only a West Coast thing?
