I'm Cody and I'm new! I live about 30minutes north of Tampa Florida...

I found this site just googling for general driving tips/mods for better gas mileage and you guys got me forking out over $100 for a SG2 in the first 2 hours or reading!

I just sold my thirsty v8 Lexus to buy a 98 civic ex since my commute is going from 16 miles round trip to 120+ 5 days a week! The civic has its stock d16y8 with a short air intake, exhaust system, lowering springs, and carbon fiber hood. There are other mods but aren't beneficial/detrimental to fuel economy.

I find it easy to get 30-35mpg out of the civic but I drive like a grandpa most of the time. With the sg2 and the downgrade(or upgrade?) to HX wheels with super light weight lug nuts (3 weight the same as 1 oem lug and cost $150 but i got them for FREE) and increased tire pressure, I'm hoping to get 45mpg. This seems like a steep 30% increase but im shooting for it! I never knew of lean burn mode so that will help as well.

All my experiments will start next week after I get the new car registered and my SG2 .

Welcome to EM, Cody! You won't regret the SGII... Check out easy and very effective aero mods, like upper grill blocks, etc.

Welcome to the site.

FYI your EX does not have lean burn mode. Only the Civic VX/HX does.

Good luck on the 45 mpg. If you slow down enough you'll hit it, but just those few changes won't get you there.

The motors are the same for these cars minus intake manifolds and other small things. Do you know exactly what is different that makes the HX have lean burn? I can swap in an ECU from an HX and my car will run fine minus having vtec. I know a couple of performance oriented ECU tuners that mainly do boosted engines and im going to contact them and see if they can chip an ecu to fuel economy.
