Speck: Fuel Consumption
I've photographed notable moments on my MID fuel economy display and put them in a forum photo album called Consumption. Feel free to visit this and my other photo albums. ![Smile](images/smilies/smile.png)
These are from my morning commute in to work. I usually start somewhat early - 06:00, sometimes 05:00, so traffic is minimal and I can experiment with light acceleration without interfering much with other drivers.
I don't always start at the same site. The first few readings are on a route that has moderate elevation changes. The other route is mostly downhill, starting with a gentle grade with an approximately 100' hill about a half-mile from parking. Coming home at the end of the day I can readily see the difference in fuel economy going uphill. ![Smile](images/smilies/smile.png)
In both of these routes, there are a fair number of stops necessary, both stop lights and stop signs. I imagine my numbers would be much improved if I didn't have to stop so much.
I thought I'd post my results here. Keeping track of the fuel consumption display has taught me that subtle changes can have a big impact on how much fuel this car needs to get me around.
Sorry the pictures are so big. I want to scale them down. I also have some photos that I need to rotate for proper orientation.

Approximately 6.5 mile drive at 35 mph +/- 5 mph speeds. Ambient Temps 56° F.

Morning commute.
OAT:52°
Speeds roughly 30-35 max. More intentional light acceleration. This car responds well to to light acceleration and rewards patience. ![Smile](images/smilies/smile.png)

Morning commute, at the bottom of the hill when the mpgs were at their peak. Final result was an improvement over yesterday, so I'm still learning.
OAT: 52° F

Please do not try to photograph your instrument display while the vehicle is in motion.

Now that's what I'm talking about.
I got lucky with timing on lots of traffic lights.

Mind you, aside from inflating the stock tire pressure to 45psi, this car is in it's stock form. In addition, I am a novice when it comes to fuel efficiency, compared to others here.
It'll be interesting to see if I can improve on this as outside air temperatures (OAT) warm up.
Also, this is only my third tank of gas. I suppose I have some improvement to look forward to as the drivetrain wears in. I'm also interested in seeing how the fuel economy turns out on this fill-up. I've been trying to note the difference between calculated consumption and what the B display reports.
Looking forward to adding more. Let me know if anyone thinks this should be it's own thread.
Gracias amigos!
