Here's another hypermiling update. (Original story and first update.)

In addition to my normal driving I did some highway driving recently. According to Google Maps, the trip was about 112 miles each way, almost all highway. During this highway trip I tried to follow big semis, generally keeping back about 2 seconds. Speeds varied from low 60's to low 70's. On the return part of the trip, on downhill sections, I put my transmission into neutral.

I just filled up. 9.86 gallons for 348 miles which is in 35 mpg range.

224 (112*2) miles was highway, leaving 348-224=124 for my regular driving. Assuming I still got about 25.3 mpg for that then I used 124/25.3=4.9 gallons for my usual driving. That leaves 9.86-4.9=4.94 gallons for the 224 mile trip.

That's 224/4.94 = 45 mpg! Are you kidding me? Can someone have their 5th grader check my math?

This Is My Pudding

Four weeks ago I posted this about hypermiling. For a short time I tried the non-powered gliding (auto-stop) but that just seemed f*cking crazy. Lately, I'll just turn off my car at a long red light. I assume my tires are still near 40psi. My driving has been nearly identical otherwise (where I go, how often, speed and whatnot).

Today I filled up. 13.1 gallons. 332 miles. That equates to 25.3 mpg. Compare that to the 22.7 I had in my previous post. An increase of over 11%.

And please, no more discussion about traction unless you have a degree in Physics.
