Okay so I just bought a 2002 Accord V6 and im getting horrible gas mileage! I knew it was going to be a gas guzzler but, not like this. I was informed id get about 20 MPG's but, I'm only getting roughly I would say 14 MPG's at best. Could someone tell me what could be going on? Do I need a Tune up? Replace air and fuel filter?? Any suggestions would be great.

THANKS!

 

Plugs,wires,rotor,cap,fuel filter and air filter would b a good start. How many miles on the motor?

 

ok Thanks!...It has almost 125,000 on it.

 

Yep full tune up.. also get a fuel induction service done...

Will make your car smoke nasty for a day... but thats all the crap its cleaning out..

I kept running lucas fuel system treatment in my van.. and made a big difference.. i was getting about 220-230 miles a tank... now im getting around 300-320 a tank...

 

any check engine lights on????if so check into your o2 sensor

 

SEA foam ftw.. should fix ur problem along with a tune up

 

Eh I would try what chris said before sea foam. Also is there smoke coming out of the exhaust? Whats your driving style? Do you go higher than 3000 rpms often? Did you fill up the gas tank all the way and check your miles when it was close to completely empty?
