That's right ladies and gentlemen, I did it, today I managed to get 404 miles in a single tank of fuel. For this drive I stayed within 2 mph of the speed limit, except the 4-5 passes I had to make. I did not use any of the tricks to improve mpg -coasting in Neutral, tailgating etc.

Here are the environmental conditions.
Temp - 78- 98 F - yes hot as hell !
Wind - some, but I do not know speed or direction

Car-
AP1 - stock with K&N drop in filter.
Air pressure in tires = 36psi
Electronics - radio with my ipod, navi unit, and gps (for tracking alt and speed)

The drive and roads
Altitude = 10 ft to 4193 ft (including 4 climbs of 1000+ ft and 2 climbs of 2500+ ft)
Max speed = 79.1 mph
Ave speed = 50.1 mph
Top down = 369 miles Top up with AC = 35 miles
Interstate = about 150 miles
Secondary Roads = the rest

Cluster at the begining of the drive.

After stopping for gas. The recipt is hard to read, but it was 11.511 gallons. Yes that equals 35.10 mpg.

 

Congrats - you've proved it can be done - now get back to driving the car like an enthusiast!

 

All I wanted to do was prove that it could be done.

 

gorgeous backround

 

404 - Gas Mileage Not Found

 

wow really impressive.

 

 

Damn. My wife and I will be driving to Idaho (no, you da ho) in a few weeks. It's straight and flat. I'm hoping to test the mileage but I doubt I will see more than 300 miles per tank. I don't get it???

 

that's wat i thought at first lol...

 

Awesome. I get right at 30 MPG highway, but that's with top up. I do need to add some air in my tires, maybe that will help. Anways, congrats! Good to know it can be done.
