How much Sea Foam in the oil crankcase for an F150? [SOLVED]

I have a 2015 F150 with 145k miles on my engine. How much Sea Foam should I use in the crank case??

Thanks for the question, Michael.

The ratio of Sea Foam to add to oil is the same for any engine. Add 1 oz of Sea Foam per quart of oil.

We recommend adding it about 100-300 miles before your next oil change. That way the Sea Foam has time to clean, and the re-liquified deposits can be drained away with the old oil.

Hope that helps!
