I took my car to have oil change and tune-up when when mechanic turned car on there was a loud knocking noise and it was blowing white smoke. I heard mechanic tell another mechanic that they put the incorrect oil in my car. They put 20w50 when it takes 10w20 therefore I took my car to the dealer and the dealer says I have a blow rod. So. I just was wonder if there was some way I could prove this happen?
