    As my wife and I are about to purchase a Skoolie conversion RV with a diesel engine, I want to be sure to use the correct additives and avoid any undue wear & tear, esp. on the fuel pump. Federal and State laws prohibit the use of hi-sulfur diesel fuel. Low-sulfur has a tendency to rob the fuel pump, valve train & other parts of lubricating properties. I am looking for re-assurance that your fuel additive is the correct product for our future vehicloe. As we do not yet have posession of said vehicle, I am unable to tell you the engine mak, model or size at this time. So a general answer on your part should suffice.
