Unless otherwise noted in the logs, I fill exclusively with 89. The only reason for that is one of the 'perks' my employer provides is on-site gas pumps with payroll deduction, priced at wholesale. I haven't noticed any difference between my daily driving and the times when I've filled with 87 during a long trip.

Someday I might even beat that wascally kenny!

No whammies... no whammies... no whammies...
