Can Sea Foam Motor Treatment be used in the oil of a 7.3L Powerstroke diesel? It has the HEUI injectors that use engine oil to pressurize the injectors for firing.
Good question, Bill. Yes, you can use Sea Foam Motor Treatment in the oil of a diesel with HEUI injectors. Sea Foam does not alter viscosity and is safe for your engine.
