Add Sea Foam before or after oil change [SOLVED]

Is it safe to put in when they change the oil or should I wait until my next oil change?

Hey Daniel – we recommend adding to oil about 100-300 miles before your next oil change. You can add it at any time, but here’s why we recommend that mileage:

Sea Foam in oil works to reliquefy residues and deposits so they can be drained away with the old oil. It’s a very good cleaner. Adding Sea Foam 100-300 miles before you change the oil does two things:

  1. Gives the Sea Foam time to clean.
  2. Lets all the crud (the residues and deposits that Sea Foam cleaned and reliquefied) drain away with the old oil. That way the dirty oil is not circulating in the engine for too long.

That said, you can safely add Sea Foam to the oil at any time. Just keep an eye on oil color and change it if it gets dirty enough (you might have to change it before your next scheduled oil change).

Keep adding Sea Foam before each oil change, and it will do a great job cleaning up the crankcase and oil passageways over time!

Hope that helps!
