Certainly didn't buy buy my S for mpg's. No fun there. Top down, winding gears til vtec kicks in and taking corners at top speed.......Now there's thrill!And I'm an older guy.

I just waxed my car too, well see if I get any gains there too =D! And I bought the car expecting to pay 18-21 MPG, I'm not at all saying I don't like owning the S2k cause of the MPG as some of you are implying, I'm just saying I was shocked/happy to see I got 30 MPG!! As for my PSI, I already had a feeling it was a lot, but the ride feels a lot smoother than having it lower (its not like im riding on wooden wheels, more like shock absorbers). I will lower my PSI on next fill up (after I see if the wax has an effect), and get back to you guys XD

62mph?! That's no doubt the reason for high fuel economy. But 30mpg ain't special. My '06 gets 28mpg at 80-85 mph on the interstates.
It's not about rolling resistance (tire pressure) but about air resistance (the shape of the car) which is an exponential factor and is approximately twice (2x) at 70mph than it was was at 50mph and four times (4x) at 100 than it was at 50. Overcoming more air resistance requires more power and more power requires more fuel. Slower speeds use less fuel per mile.

I do the same driving speed and clock an easy 270-300 miles each fill up at appx 10 gallons. The best I clocked was 34 MPG when driving long distance. I do not like to drive slow. I suppose I average 80 MPH.......
I make sure I include a few spirit driving each tank
Also that tire pressure is nuts. I have 33 psi in all my tires.

I generally drive at or under 3k RPMs, usually under unless in 5-6th gear. I only gas up at Shell. And I generally go speed limit on the streets, and 62-75 MPH freeway. I notice if I drive at 62 MPH my gas survives a bit longer. Also I pumped the air in my tires to about 45-50 psi which is either max or recommended, I forget which but probably max. These are all the things I consciously do in order to save gas. But I don't think doing just this would give me 30 MPG! I have no mods on my car, just a Quick release steering wheel.
Any ideas on what I'm doing right? Or is it everything I just stated?!

If you are looking for high MPG... prolly need to go to a hard top. Roof down = lots of air turbulence, but very high FAF (female attraction factor).
Ragtop up = not the greatest slipstream.I would not ride on 45-50 PSI. These car are very sensitive to a few PSI air difference. At least that is my experience on Potenzas. At 50 PSI, you must have some crazy understeer-oversteer transition issues.
I don't think you'll ever get the mileage, of say... a TDI VW Jetta, no matter how much you tweak the ECU. But, the S2000 has other advantages over the VW. No?

Since I use my S to commute to work (62 miles each way), I monitor my MPG. It's always good to monitor this so you know that everything is working as everything should.
I currently get 29.5 mpg. My best was 32 mpg.

I've literally never seen anywhere near 30mpg in an s2000, even on an all freeway drive. My Corvette regularly gets 30mpg on the highway though, but it runs 1400rpm@75mph with half its cylinders shut off... Torques, it has them.

higher pressure = less contact patch = less traction = higher chance of dying. However, lower pressure isnt good either, unless you're rock crawling, mud bogging (also have to consider ground clearance), or sand dunes.
