I wanted to encourage everyone out there who drives a regular route to keep a daily log. I started mine back in May and over 40 days (work days) I've improved my FE by around 40%. According to my in-cab display the average of my first 3 days (6 trips) was 29.1 mpg. The average of my last 3 days was 41.2 mpg. FYI, I know it reads ~15% high. I went through 4 tanks and my 1st tank was 25.74. My last was 33.91. That's a 31.7% improvement.

I've done a few physical mods (upper grill block, bed cover, tire pressures), but most of it has been driving style and route selection. I actually didn't spend any money at all on mods during the 40 days.

So if you're not keeping a log, I would encourage you to start. I found it helps a lot to see what's working and what's not. It's also fun to see how well I can do. Every day you see if you can set a new record.
