Can't wait to hit 80 in my car!




Yes...I am kidding.

Awesome mileage, how many are in the 80+ club now? 5? Pretty elite!

Just had my best tank ever in the geota,
06/03/2007........ 305 miles..... 5.5 gal...... 55.45 mpg.
getting up there with the big boys now
Lots of short trips around town, lots of EOC .
I think thats the best ever for me, I think I had a tank of 54mpg in my old festiva.

Larry, you're bearing down on me and Old Reliable. With a car you have owned for a week!! I am pulling over, come on by.

This is my record segment from a few days ago. 163 MPG, 49 mph avg, 33.1 miles, 36 minutes. No wind, 1860 net elevation drop. No wife, no cat in car. Had 106.4 for the day.

Damn, 20mpg again. I've got the tires at 55psi now (factory suggests a max of 35). I'm gonna try to do more EOCing and maybe different cruising rpms.

Maybe manual unlocking front hubs to reduce losses in the front drivetrain?

That could work, but I'm not planning on keeping the truck for too long. I started doing some hardcore P&Ging and I think it'll put me into the 25-30mpg range. 30mpg is my goal.

I'm starting to see why hybrids make sense. I'm working for the school district in my hometown and their base is in the 'downtown' area. I'm in and out of there throughout the day and it's a lot of stop & go, slow moving traffic. It'd be nice if people knew how to drive because everything would flow much more smoothly.

Pulse and Glide is basically Pulse Width Modulation. The injectors use PWM, but they have to keep the engine running. As drivers, we know when we don't need any fuel, so the decision can be made to use the energy that has already been produced.

Also, I don't have OBDII or a SuperMID, but I know that those of you with SC or SM are able to determine the sweet spot in your RPMs quite easily. Does it occur at the same sweet spot for keeping the RPMs fairly constant when changing gears? (In other words, if I'm in 3rd gear at 2500rpm and I'm able to shift to 4th and it stays close to that, say 2200, that should be helping the FE, right?) Just curious because there are trade-offs with running into higher rpms, but I'm new to the idea of the 'sweet spot' for economy.

It's becoming even clearer to me as well. Just guessing, my car's engine could be shut off for 80% of the time that I am driving. Using an idle consumption of .5 gph, it looks like I could save about 10% on gas if I were able to capture all that downtime.

I just measured FE for my metro after inflating the tires, adding wheel skirts, EOC coasting, neutral coasting, easy exit parking, and driving conservative.

After 61.1 miles I used 3.172 gallons which comes out to 19.26 mpg.

There's no way on earth that can be right. I think it wasn't completely filled the last time I drove it - something.

I'm redoing that and because it's off so much I'm not adding it as a FE entry.
