Sea Foam in oil – 2020 Ford F250 3.5L turbo [SOLVED]

I have a 2020 Ford F250 with a 3.5 turbo. The information I read instructs that I add Sea Foam to oil about 100 to 300 miles before I change the oil  and filter. If that is the recommended use of Sea Foam, how many ounces would I add to 7 quarts of crankcase oil?

Hi John. Your description on when to add is correct! For a 7 quart oil crankcase, a solid rule would be to add half a can of Sea Foam every interval. Note that you can add 1 to 1.5 ounces of Sea Foam per quart, so you cold add as much as 10.5 ounces.
