So, I just purchased an 04 Honda Civic. Automatic. 2 dr. LX Coupe. And, I couldn't help, but notice as I was driving around running some errands. Like going to get my new nav system installed that my gas meter was reading kind of low. Its not a very powerful car, and I havn't done anything to the 4 cylinder engine. Why am I burning so much gas?

The reason I purchased this vechicle is cause everyone brags about the quality, and mpg. Frankly, I'm disappointed.. .

 

flush your tranny, change your oil.
it should be getting 30 easily with an automatic. i'll vouch, and i have an 02

 

I have an 04 civic auto 2dr lx as well. I average 28-30mpg... no engine mods. just k&n air filter, 215/50/r16 tires, and light wheels. This is also mostly city driving. maybe only 1/3 of my tank is highway.

 

Thanks guys. I don't know. I'm moving to Cali. I'm at 99, but I'm thinking I'll get the 110,000 mile service done early to atleast knock off $3-400 off the price plus an oil change.

 

i get about 25-30 mixed. this is with both 185/65/15 stock SI's on Bridgestone HP AS's and 225/45/16 on Advan SA3R's with Hanook RS-2's.

 

i get about 30-33 on average. (02 Ex Sedan) With a AEM Sri and 215/45/17 tires.

 

I forgot to mention that im running a stage I crower NA cam, SRI, header, and cat delete for engine mods. I also had a full greddy evo II exhaust on it before but the gas mileage was similar.

 

I have a 04 lx 5spd and have got as much as 42mpg I average around 38mpg !!!!!!

 

I avg about 29-32 with turboed 02 lx 5spd with 205/45/17's

 

oil,air filter,plugs,check tire pressure maybe try a fuel system cleaner, use the lowest octane fuel you can get and you should be good.
