Did my first track day in the S2000 this weekend. I was surprised at what good gas mileage the car *seemed* to be getting at the track, much better than other similar cars I have driven at the track.

Well, I trailered the car home from the track and drove it to work today (first time I've driven it since the track day). About 2 miles into my morning commute the gas gauge went from 4 bars to none in about 10 seconds. Luckily there was a gas station nearby as I almost ran out of gas.

I did a search and it appears an inaccurate gas gauge is a known issue with these cars so it seems to make sense to pay closer attention to the mileage. It's never been a problem on the street for me though.

Since I didn't pay any attention to the mileage at the track this weekend (was relying on the gauge). What *ballpark* MPG are people seeing at the track? I think I'll be watching that instead of the gauge next time.

Thanks

 

9-10 MPG for me.

 

I saw 7mpg at Gingerman. Car is stock with Hankook street tires.

9mpg at Le Mans, 12mpg on the Ring

I've had fuel starvation problems when the car has less than 7L in the tank.

 

Thanks for the info. I would have guessed in the 9-10 range depending on the track and the driver.

I have read about the fuel starvation issues. The track I was on really didn't have many/any long sweepers. I guess that's why I did okay in my last session even though I probably only had 1-2 gallons of gas in the tank when I pulled off the track for the last time.

 

I reset the trip meter when I fill up, and when I get to about 90 track miles then I'm running on fumes. Ignore the guage.

 

9 - 10 mpg also. Like mike said the gauge can be woefully inaccurate. I'm seen the car stuttur like it has no fuel with 3 to 4 bars on the gauge.

 

I also got about 10 mpg at the track. My fuel gauge made a quick descent on one of the laps and while I was at nearly 8000 rpms in 5th, I must have run out of fuel and it felt like I hit a fuel cut. Could anyone explain what might have happened? Was there just not enough fuel to deliever the correct air/fuel ratio and the fuel pump temporarily shut off to save the engine? Or might it have done more damage to the engine than I had thought?

 

I top off every two 20 minute sessions. My prep before each session is, check the torque on the wheels, top off the gas (if needed), check the oil.

9-10 MPG.

 

7-8 mpg for me....car has rear wing, race tires, and race pads otherwise it is totally stock.
