Should I use thicker oil with Sea Foam in the crankcase? [SOLVED]

When I add Sea Foam Motor Treatment to my oil crankcase, should I use the same or a thicker oil?

Thanks for the question, Thomas. Use the same oil that you normally do – whatever the vehicle manufacturer recommends. Sea Foam Motor Treatment is made with petroleum ingredients and won’t alter the oil viscosity, so no need to use a thicker oil. Hope that helps and let me know if you have any other questions!
