turbo lexus pile
i drained the oil out of my car and it was kinda green. i ran 4 qts of mobil 1 0w40 to clean the motor out, didnt run it, and 4 qts came out, just a little green looking. if there is coolant in the oil sys., what possible ways is it getting in there? leaky HG? or does M1 ow40 just have a greenish tint to it?
