I get roughly 280-300 miles per tank and 27-30 MPG driving mostly highway in my 01 AP1

 

Your mileage is about average for city and slightly spirited driving. If you want to shave MPG, redline it. If you want to improve MPG, buy a Pruis.

 

City I get about 17mpg on the way to the dragon top up I got 23.3mpg, top down 20mpg. While on the dragon I think I got like 10mpg lol

supercharged '01

 

I get over 28mpg and that is with over 31k miles tracked. I have no complaints on gas mileage on how and where I drive my car. OK I do have one complaint on my gas mileage, the faster I go the lower the mpg gets so when I'm going 85+ mph my mpg is down to 23 or 24 mpg.

I bought my '02 with ~37k miles on it, currently at 39,99XX. My gas mileage is as described in the earlier posts, at or around 21-23 with mixed city and highway for the last 3 months.

Compression still needed?

 

Civic's/integras get you good gas mileage but the S2k is where the fun is at... Sometimes you just have to sacrfice if you wanna have a good time while driving. At best I've gotten 225 miles out of a tank. Average is about 210-215...

Luckily for us even though the cost of fuel is expensive everywhere the small gas tanks sort of make up for it.

 

B.S. Fuel economy is a big factor for me, and I buy/own *only* sports cars. Fuel economy is the main reason I got the S2000 instead of an RX-8, though I wanted +2 seating and a fixed roof.

The most important thing in a sports car to me is *light weight*, which is also good for mileage. Low drag is also good for economy and performance (no-downforce street cars, not winged track cars).

For several years the 1st-gen Lotus Elise had the highest observed mpg (35, I think) in the back of Road&Track where they summarize performance of cars they test.

FWIW, I got 328.3 miles on 11.17 gallons when I filled up last night, 29.4 mpg. Last tank was 30.x. That is mostly highway, of course, but some stop/go traffic in there, too.

Keeping tires inflated (duh) and running minimal rear toe-in (I'm running 0.2 degrees total) helps.

 

I agree. This is a sports car with very respectable mileage for the performance. Reliability turned out to be just as good of a reason for you to buy an S instead of an RX8. My 04 was a nightmare. Covered by warranty thank god, but slower than an S, guzzled gas (22-23mpg best on highway (this was with ethanol free gas, and averaged 18mpg even babying it), and saw the dealership 5 times for repairs in 22k miles of ownership. With enough manipulation, I even pulled off 30+mpg in my STI and my Mazdaspeed 6, with cruise at 65mph. Painful to do, but it worked.

Anyway, I am amazed at people getting close to 30mpg on their S nowadays. Ever since 10% ethanol became permanent where I live, I haven't been able to come close to it anymore. My former AP1 got 30+ mpg easily back in the day (highway driving). I easily lost 4-5mpg since I stopped being able to get ethanol free gas now. I get 25-26mpg tops on highway. A few years ago, I could pull off 28-30mpg on highway without much trouble. Ethanol for me effected this car more so than other vehicles I have owned. My VW didn't see the mpg hit the S took.

 

10% ethanol should only account for a ~3% hit on fuel economy, nothing like 4-5mpg!
What are your toe settings?

 

I just got 295 miles on my first tank. '02 AP1 with 130k miles. Thats about 25 mpg!
