Drove 340 miles today in my C230 Coupe. I got 34 miles per gallon. It was 90% interstate. My best prior to today, on this same route, was 29. My worst was 24. What I did differently today was: use the cruise control and stick to the speed limit. It made a big difference. I support our troops and I'm going to do everything that I can to reduce our dependence upon foreign oil. No more blood for oil. Oh, and did I mention that I got a $160 speeding ticket on Sunday?
