Hi. Bought your engine oil stop leak a few months ago. I notice after using it, yes my oil leak become less in fact I can no leak. But every time I start the car, white smoke out at exhaust, only during initial start and during driving not as much as during start. Is that normal?. Will the white smoke gone at later stage? Thx
