Thanks guys.
I would say I lose about 2mpg because of biodiesel, so maybe 5% drop max. Its hard for me to say exactly because I use biodiesel in the summertime and switch to an only 20% bio blend for the winter. So the straight bio has the benefit of warmer operating temps. End result is basically steady FE all year long.
I know everyone recommends driving style as the primary method of FE increase. I understand completely, and try to draft, coast and anticipate as much as possible. But when I wake up late for work I have to get here asap, meaning 80mph plus on the highway. Driving home I cruise much more. Now that my ECU is chipped I also like to accelerate a bit more.....
But my commute is about 40 miles of daily highway driving. Yes, I drive too fast. Often I have no choice but to go with the flow. But there still must be some gains that could be made in drag reduction. What do you guys advise as a next step?
I would really like to build a deck lid extension that tapers down gradually and in on the sides. I think lighter wheels with LRR tires and rear skirts are on the list too.
