As was said above, if you're only getting 25mpg on the highway, either your not in the correct gear or your're too happy with the gas pedal. When I'm doing highway driving, I dont think I've ever seen below 27mpg, with my best being almost 32mpg. Thats cruising at around 75mph in 6th gear.

 

300 car will runs you alot more later down the road, you don't just get a used car without problems, esp when it's around 3 digits.

try shift around 3-4k, new air filter, sparkplug and keep the a/c off

 

Some things you could do would be:
1. Get lighter wheels that are all the same width and put some skinny rock hard tires on it
2. Use 38psi of air in the tires
3. Drive with the top up! Less drag.
4. Stay below 5000 RPM's at all times
5. Never drive faster than 65MPH
6. Get a free flowing exhaust
7. Get a good intake pipe or modify the stock box
8. Take all the tools, carpet, spare tire and anything else out of the trunk
9. Use cruise control when you can
10. Make sure you have clean filters (Air, Fuel, Oil,)
11 Change your spark plugs
12. Always use premium fuel. If you don't your car will start to ping and will reduce the timing to compensate. Witch will give you less power and worse mileage.

Oh, and reset the ECU!

 

just get a beater to drive to work, and use the S to have fun. on a full tank for the S i get ~260. I'd get a beater for a DD but i love to drive the S more.

Just shift under 3500k and be light with your right foot.

 

this has got to be the dumbest question posted on this site in the last 6months.


wow.

 

why did you buy an S2000? you should have opted for the civic or corolla, or maybe hyundai accent or something...

i never post to flame people but uh......

lol

 

Agreed. But atleast we are on par with the Evo forums. "If I turn down the boost, can I get better milage!??"

These people need to look at a Fit or a Yaris.

 

to add to the things you might consider, change of rear end ratio/gears, to a higher gear, that will mean your engine is turning less when you are at speed, thus better mileage...i would not do this....all i would do have been outlined to you above in the excellent reply by many others....just stay off the gas and under 5500 rpm, no vetc means at least 2-4 mpg better...whatever you end up spending money on must be offset by the savings of gas of you have not made any progress....this is not an economy car, for that you need a prius or civic hybrid...or even a stock civic...i would just enjoy till have you have change jobs again or move closer to work!

 

you can drive above 6000 and stay out of VTEC, VTEC is activated when:

The RPM are above 6.000 AND
There is more than 75 psi oil pressure AND
The throttle are above 60% of their motion range, not very sure about the percentage.

 

explain to me why some of you suggest to the OP to spend $$$ when his goal is to SAVE money to begin with?

test pipe? $100
gears? $1000
intake? $300
exhaust? $500
tune? $250/hr
VAFC for the tune? $300
buy another car? $300 for the car, $200 for registration, couple hundred more for insurance......



i say to do a full tuneup on the car. use lighter weight oil for the engine and diff. over inflate your tires about 5-10 pounds. if you need new tires anyways, go for narrower all seasons. like everyone else has said, go easier on the gas. mpg can improve dramatically if you drive behind larger vehicles but this will slow your commute a lot. i got 36mpg once by drving behind a semi on cruise but it added an hour to my 3 hour drive. agian, top up will decrease drag and improve mpg.
