My vehicle is a 2011 Ford Mustang 3.7L V6 with almost 130,000 miles. Is it safe to use Sea Foam Motor Treatment and/or the High Mileage version in my engine oil that already has Restore Engine Restorer mixed in with it? I use Restore after every oil change for the life of the oil and I would like to add the High Mileage treatment to my oil before my next change. I just want to make sure that it is ok to combine those two products. Thank you.
