I get exactly 13.6 mpg.

 

For a (mere?) 17% increase in speed we find a (staggering?) 38% in drag. Staggering is a subjective term and an admittedly poor term for an engineer to use. But it's a lot for a little.

 

The most miles I've driven on a single tank of gas in my S2K was 336 miles. All those miles were south bound on I-5 in Northern California traveling at 90+ miles per hour... with a long stretch of 140+ mph cruising.

Oddly enough, the tank of fuel in which I traveled at the highest average rate of speed yielded me the highest average MPG.

BTW: Hardtop was on the car.

 

In the range of 26 mpg. Wow!

 

(That's assuming using 13 gal.)

 

Approximately 11.5 gallons is the most I've ever pumped into the tank. I've never ran out of fuel.

 

11.5 gal means 29 mpg. Shite.

 

I don't think there are too many cops out there, or even airplane-mounted cops and more likely than scraping, they'd be picking you out of the trees

 

I get in the 36-38mpg range fairly normally on trips down to portland in my civic I'm curious if my car with a k20a2 or k20a would maintain similar gas mileage or if it would slip down into S2000 ranges

 

I have an iMPG feature on the computer I installed in my truck. I've found cruising out on the freeway it's pretty easy maintain 22 iMPG to 30+ iMPG (the computer peaks at 30 iMPG) while traveling 70 mph - 85 mph. What brings the average MPG back down is accelerating and trying to maintain those speeds climbing hills. The iMPG drops to 2 - 4 iMPG during acceleration... unless you go very easy on the throttle. But even then it will drop to 6 - 9 iMPG.
