I need to maximize my time when taking the kids to swimming lessons, every bit counts!When our dealer fill 87 ran out, we filled up with 93. In our semi spirited driving tests, there was no discernible difference that was obvious. As yrwei52 mentioned, it only helps above 4k rpm. We'll try it again in a few months, when the weather improves to where that kind of testing is more appropriate. Since the "feel" is more torque related, I doubt our opinions will change much.
Jokes aside, I will try it out so my butt dyno can evaluate.
