Ever since I found the product OilStopLeak at AutoZone, I have been recommending it to anyone who has an oil leak in their car. It is amazing how it seals the leak in my vehicle’s oil pan instantly. The cool part is that I remember when my mechanic mentioned the oil leak in my vehicle for the first time.
