Adding Sea Foam to 2008 Crown Victoria oil [SOLVED] Asked by Leon B. In South Carolina How long do I let my 2008 Crown Vic run after adding Sea Foam to the oil?
Hi Leon. Whenever adding to a car or truck oil crankcase, you want to run at least 100 odometer miles to give Sea Foam enough time to circulate and clean. The can shows add at least 100 to 300 miles before changing oil and filter. Hope this helps!
