on the entire rear of my car theres this like mist of black stuff on my car. i can whipe it off but it comes back after i drive some people said it was old, think it might be rubber. i have a mangaflow exhast on it. and si rims and its lowered a little. does anyone know what it is and does it happen to you?

 

its unburnt fuel

 

Rubber? No.

If it's black, it is unburned fuel. Common for VTEC motors, and even more so if you have an exhaust and drive it in VTEC most of the time.

 

yes id have to agree more than likely unburnt fuel, does it leave any residue/streaks when u wipe it off? check underneath for any possible leaks, granted im sure we know what burnt or burning oil smells like so id say if u dont have that foul smell while driving your good.

 

i use simple green to clean the back of my hatch off. it works really good
