The Octane ratings for Canadian gasoline for Regular, midgrade, and Supreme are 87,89, and 91 respectfully.
I understand that the US ratings are 89,91,93. Is this actually the same fuel?
So if I installing a Diablo tune on my LX and I use Supreme, do I use the 93 tune or the 91?

Pretty sure they use the same ratings, for 91 octane use the 91 tune.

Only two things are infinite, the universe and human stupidity, I am not sure about the former.
I'll install a tune once it stops raining and I can find a dry piece of pavement to sign.
