I will see if there is any differences with the next tank and try to make a comparison between 87 E10 and 89 E10 and how the vehicle runs with either on in the tank.

I maybe have skewed data myself as I finally go to get the smooth wheel covers on the front of the car. So I may need to do another 89 octane tank to properly compare."
