Thanks for the question, Eddie.  Yes, you can add the Sea Foam directly to the oil. Add 1 oz of Sea Foam per quart of oil in the crankcase.

We recommend adding it 100-300 miles before your next oil change. That gives the Sea Foam enough time to circulate and clean. It also lets you drain away all the reliquefied crud (residues and deposits) when you change your oil.

Hope that helps and let me know if you have any questions!

Thanks for the question! Yes, it is okay (it won’t hurt anything) to add Sea Foam to your oil 3 days after you’ve changed it. It will clean and help lubricate for the life of the oil. That said, we recommend adding it 100-300 miles before your next oil change.

Sea Foam reliquefies oil residues and deposits so they can be drained away with the old oil. It’s a very good cleaner. Adding it 100-300 miles before your next oil change gives the Sea Foam enough time to circulate and clean. It also lets you drain away all the reliquefied crud (residues and deposits) when you change your oil.

If the oil burning is caused by oil residues and deposits, Sea Foam will help reduce it.

Adding 1 oz of High Mileage (what I would use) per quart of oil during every oil interval will progressively help to reliquefy the heavier oil residue that’s plugging up your engine’s oil flow. If high miles, you may also be dealing with worn compression rings that would allow oil to end up in the combustion chambers. In any case, keep adding High Mileage to your oil each interval and pay attention to oil consumption.
