Will Sea Foam clean my oil sending unit filter? [SOLVED]

Hi Paul. Can generally say that adding Sea Foam to help clean an oil sending unit is definitely worth a try! Add 1.5 ounces of Sea Foam per quart of oil in the crankcase. If your car is older with higher miles I’d try Sea Foam High Mileage, which is a bit tougher on stubborn oil residues. Note that a Sea Foam crankcase treatment requires at least 100 drive miles to circulate and clean. Please keep in mind that we don’t know the specific cause of your engine oil issue.
