I have oil pan gasket leak, can I use stop oil leak additive to stop the leak? thank you
The best thing to do would be to replace the oil pan gasket. According to the labor time guide it calls for 2.5 hours. However that is not what you asked, so let me address your question. According to the oil stop leak additive manufacturers the product swells existing gaskets and will not seal larger leaks. That being said, I suppose the size of the oil leak would have to determine if it would work or not. You could always try it and see for under $20 it might be worth it to see if it does. Let us know how it turns out if you do decide to try it.
