I have a 2000 civic EX 4 door and I was just wanting opinions on different upgrades that will help increase fuel mileage? I am already planning on installing a cold air kit (not sure what brand yet). this is my daily driver so reliability is a concern. any opinions would be appreciated.

ahahahahahah


but seriously, keep your tires at the proper psi, and don't always be on the gas pedal. that works for me

The biggest "mod" you can do is change the DRIVER. Shift early and get into 5th gear as soon as possible without bogging the car down too bad. Drive 55-60 on the highway when safely possible (don't impede traffic). Coast up to stop signs and "time" stop lights so you don't have to stop.

Also, invest in a ScanguageII. It shows instant MPG stats so you know what works and what doesn't.

Other "mods" that will help:
HX Transmission (longer gears)
Lightweight wheels (from Civic HX)
Hard compound tires inflated to maximum sidewall pressure (treadwear still debated)
Lowering the car
Weight reduction
Front grill block (without totally blocking radiator)
Rear diffuser to keep air from being trapped under the bumper

I would personally not waste my money on a Cold Air Intake. IMO, it is not going to give you a big enough boost to justify the cost. I would put that money toward buying a ScangaugeII.

also would help is putting on little bolt ons like intake header exhaust and then getting a tune, seen a few cars get in the 40mpgs after doing that.

I was averaging 40 on a stock d16y8 with no mods at all. Personal best was 44 mpg on 1 tank. I'm currently getting 30-32 mpg consistent on my stock gsr with b16 transmission... and that's including raping it around a little bit. It's all in the driver.

I disagree with the notion that you should try to get it to 5th gear as soon as possible and stay there. Think of it this way - you're cruising at 25 mph in 5th, and decide that you want to accelerate to 60, using 5th. In order to do that, you have to use a lot more throttle, for a lot longer than if you had downshifted. I know a lot of people (including myself) have the tendency to want to stay in 1 gear, but it's bad for fuel economy.

In my experience, you use less fuel by using less throttle, which means always using the appropriate gear and the least amount of throttle for the acceleration you need. Anytime you're above about 30 mph and need no acceleration, you should be using 5th. If you need acceleration, then downshift.

Don't use neutral to coast into stops. Coast down in gear. While coasting in gear at zero throttle, the engine uses almost no gas to stay running - the force of the wheels turning with the momentum of the car keeps the engine turning over. As soon as you clutch in, the wheels disconnect from the engine, and the engine requires fuel again to keep running at idle. Whenever possible, coast in gear as close to a stop as you can. Drive as if you have no brakes.

And get a Scanguage. IMO, it's the best tool for seeing habits in your driving that hurt your fuel economy.
