WILL A CAR FAIL THE SMOG TEST IF YOU DONT CHANGE THE OIL. AN THE OIL WAS DIRTY IT DID NOT FAIL BY MUCH ONLY A LITTLE.

Will dirty oil cause a car not to pass the smog test. I change the spark./Wires but not the oil it did not fail but by a few points on the emission sorry I dont have a donation a the moment I am low income.
