There was a Mileage option. I just pm'd a guy who I have been communicating with over the last few weeks who has one. He said he was told 87 Performance was for other Jeep models and it was renamed to just 87. I guess I have the correct one. Thanks again "Useful" pickles! BTW, I just drove up and down my block and it did feel different. I have a full tank of 87 so I am curious to see my mileage down the road.
