Do I need to change my oil after using Sea Foam Motor Treatment? [SOLVED]

If I use Sea Foam Motor Treatment in my fuel, would I have to change the engine oil after? What if I use the spray through the throttle body?

Thanks for the questions Robert. There is no need whatsoever to change you engine oil after using Sea Foam in the fuel or Sea Foam Spray through the throttle body. Hope this helps!

Good question, Edward. Yes, you can leave Sea Foam Motor Treatment in the oil for the entire oil invterval. It won’t harm anything and will continue to clean and lubricate. That said, we recommend adding Sea Foam to the oil 100-300 miles before your next oil change. Here’s why:

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 liquid crud (the residues and deposits that Sea Foam cleaned and reliquefied) drain away with the old oil. If your crankcase is dirty, that way the dirty oil is not circulating in the engine for too long.

Bottom line:

Check the color of your oil. If it’s dirty, go ahead and change it. If it’s a healthy color, just keep checking it periodically as you normally would and change it when it gets dirty or you reach the recommended oil change mileage.

Hope that helps!
