With the 35d I would get around 27-28 mpg on hi way trips. 21-22 to the office and doing errands. To my surprise on the last 3 highway trips that were over 300 miles I averaged jus under 28 mpg! I have been getting 21 for my runs to office and errands. I am really impressed with the efficiency of the gas direct injection engine with 8 speed automatic. This bridges the economy gap and it is so much more pleasurable to drive. I also was worried about warranty problems that could arise from using bio diesel.

A negative is that premium gas was $4.20 today in ILL. Which is a lot more than diesel. I will also miss freaking out the truckers at my local diesel depot. They would always think I was some idiot putting diesel into my gas engine car (my old 35d). But my hands smell a lot better these days.
