The other day i was on the freeway when my friend told me that a lot of black smoke was coming out when i enterd the freeway .. But my car seem fine to me and nothing was wrong, my car felt fine> any soultion >?

 

Yeah your friend is jealous and talking smack - is your car running rich, is there any carbon on your exhaust tip or bumper

 

your either running rich or burning oil

 

agreed , oil or running rich.

 

Oil burning is usually a blue tint smoke. Black means you're loading up. Too much fuel. Check ur air filter and make sure it's clean.

 

well umm everytime i get gas i make sure its really full.. like u know how the gas pumps make that click noise !! i sometime put and extra 2 or 3 dollars more of gas >?> why is that bad ?>?

 

a dirty air filter would cause a lean condition if anything. Also i would not fill it as much as you are.

 

so ur telling me that not to over top off myu gas ! so i should stop once it clicks>

 

i would use a higher octane, maybe even run injector cleaner? i know when your burning oil lol. my car blow so much blue smoke the nieghbors came over to see if my house was burning down. haha i just told them its a honda :D

 

You are confusing what he is saying. You can fill your tank up all you want, the engine isnt gonna run richer because of this, the fuel injected into your engine is still controled by the PCM and related control units and sensors. Your car is running rich for one reason or another, and there is a ton of things that can cause this.

 

Does your car have any serious mods and do you have any engine codes present?
