Haha, I just use 98. I remember back in the day I had $8, I still used it, $10 I still used it. It's a habbit now, and whenever I see my dad using regular unleaded I always think that his some cheapo. Even if its abit higher cost than regular, its worth it. Anyway everyone should know this by now :p
I respect the prices and its true, you pay for what you get.
