Is Sea Foam safe for gaskets? 03 Honda Element [SOLVED]

I have a 2003 Honda Element with 236k miles. It takes 4.4 quarts of Mobil 1 5w20 oil.
If I add Sea Foam or High Mileage to the crankcase will it have any effect on my gaskets ?

Hi Todd. There is no possibility of Sea Foam causing harm to gaskets, rubbers, or plastic engine components. It’s made with 100% petroleum cleaning and lubricating oils that actually work to nourish gaskets! Hope this helps!
