Sea Foam before every oil change [SOLVED] Asked by Shane A. In Tennessee Can you use Sea Foam before every oil change? My cars are high mileage and to my knowledge have never been flushed.
Yes, you can add Sea Foam to oil before every oil change.
That’s actually a great routine for higher mileage vehicles. By adding Sea Foam before every oil change, you will progressively clean away residues and deposits that have built up over the years. Once things are cleaned up after a few oil changes, Sea Foam will keep it that way and prevent buildup. Just don’t exceed one Sea Foam treatment per oil interval. Add it to oil 100-300 before your oil change.
