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.
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.
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.
B consumption display. Approximately 6.5 mile drive at 35 mph +/- 5 mph speeds. Ambient Temps 56° F.
Morning commute. Temperature 43° F. Mostly downhill. Speeds between 30 - 40 mph.
Speeds roughly 30-35 max. More intentional light acceleration. This car responds well to to light acceleration and rewards patience.
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.
