I completed a test run with my Geo (that was similar to MetroMPG's test) yesterday. These were the average MPGs (around 7 miles for each speed) in 5th gear with cruise control on (this was driving in rural Saskatchewan into a 15mph wind. Temperature at 26*F):
I just got a really cool surprise. I was near my normal gas station and saw I was going to have just over 500 miles on the tank by the time I got there so I decided to stop and fill up. I had 500.5 miles and the SG2 was reporting 50.8 MPG . I thought, "That's pretty respectible for this time of year." I started pumping and when I was finished, I put in 9.548 gallons and my MPG figured at 52.419 mpg. This is in temps that have not been above freezing for over a week. I did one significant thing different this tank: When I accelerated/pulsed, I made sure that the TPS(throttle position sensor) on the Scanguage was reading as close to 15 as possible and, as usuall, I shifted at 1500 rpm or below.
Horsepower is how hard you hit the wall, torque is how much of the wall you take with you.
That's a great tank with the weather. I was looking at gaslogs to see who has the least amount of noise. DRW you're one of the best as far as consistancy goes. Just looking at gaslogs varibility is proof enough that tank to tank testing is pretty much impossible.
Thanks. The weather around here isn't as bad as the rest of the country. Temps are usually around 35 to 40 *F in the morning, 55 to 60 at midday.
I'm trying hard to drive consistantly. I do the same commute all week and try not to drive it on the weekends. I plan to take the car to the 1/4 mile drags when the track opens again to see if it's any faster with the aero mods I've done lately. I added a few underbody panels in the dirtier areas, so my trap speed should go up. Consequently, my tank to tank consistency will drop off that week. It's all part of the fun!
I could possibly get 10 MPG worse economy if I thrashed it all the time....... but the point is, my car is a convertible, so I WILL drive it with the top down, it has A/C and heated seats, I will use those too, it has wider tires for better roadholding and stability (and looks), and even though all these items do detract from potential fuel economy, I won't change the way I use them.
But, I am starting to try and optimise FE now that I have a ScanGauge, but I draw the line at not using my car's convenience and comfort features.
