Silverhook Engine Stop Leak counteracts the effects of seal shrinkage. Older and higher mileage can develop consistent signs of engine oil loss. This can be caused by rubber seal shrinkage due to age, dryness and consistent temperature changes.
Engine Stop Leak contains seal conditioner additives to help correct external rubber seal related engine oil leaks and can be left in the system offering long-term protection.
