Draining oil before adding Sea Foam [SOLVED]

When adding Sea Foam to the crankcase/engine oil, do you add this on top of the six quarts already in the engine? Or should enough engine oil be drained to accommodate for the extra fluid? Thanks!

Thanks for the question, David. No, you do not need to drain any oil. With that amount of oil, add 6 ounces of Sea Foam (1 oz of Sea Foam per quart of oil). Your crankcase has plenty of capacity to add the 6 ounces of Sea Foam on top of the existing oil. Hope that helps!
