QI use Mobil 1 synthetic motor oil in my Dodge 5.7L pickup truck. Should I add Sea Foam Motor Treatment in my crankcase if I use synthetic oil?

AYes, Sea Foam Motor Treatment is made from petroleum and always safe and compatible with any conventional or synthetic motor oil. It also works in any gas or diesel engine crankcase. Our recommended ratio is to add 1 to 1.5 ounces of Sea Foam for each quart of crankcase oil.
