Actual savings are dependent upon vehicle/engine type, outside temperature, driving conditions and your current engine oil viscosity. §Average OEM ODI recommendation based on recommended oil drain intervals from major U.S. engine manufacturers using API CJ-4 oils for a variety of service severity levels and engine models. Average OEM ODI API CJ-4 recommendation to substantiate multiplier claims is 31,750 miles. Results may vary based on vehicle/engine condition, driving and environmental conditions. Consult OEM or ExxonMobil before implementing extended ODIs, especially if the equipment/vehicle is under the OEM’s warranty. **Based on measured viscosity increase in the Volvo T-13 test.
