True. The cost per mile at 23 MPG with 87 was $25.87. And the cost at 25.4 mpg with 91 was $26.55. So, the premium was slightly more expensive. On the same trip previously I got 26 mpg (I don’t know what the difference was). If I got 26 mpg, the cost would have been identical.

Regular Experiment Based on my experiment, premium does offer advantages on my car. With better performance and power, it took less fuel to drive the same road at the same speed. Yes, but you have not yet calculated the fuel cost per mile, which is probably what a serious road-tripper would be interested in. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
