lil rich can be bad here guys !!! lil lean is where the power is ! rich can leve deposits and eventually wash out rings. Depends on the color of smoke.
Black = Fuel
White = Condensation
Blue = oil


and if you have ricer mods and your puffing black smoke its normal its called rice !!! lol your shits not tuned right cause you did some gawd awful huge exhaust and o cat or the car is just old !

If you have oil and fuel mixing you have larger issues than just runnig a lil rich !!!
