I use ESSO, yes, we still have ESSO stations in Canada, no EXXON.
I usually put 87 octane in but once per month, I will give my RT 89 octane. The manual says not to use anything higher.
IRVING? Only in Canada you say? Only in the maritimes, I say!! I remember, back in the early 70's summer, Irving was having a promo where they seeked out whatever 'good-lookin'' chicks they could find to pump gas. Yes boyz, only gas. A gimmick, maybe, but it didn't do much for my Ford Fairlane 500XL covertible with 95,000 miles on it.
