Monarch Diesel Ultra Syn 5W40 & 10W30

Tulsa, OK - Royal Mfg has developed and is promoting a full synthetic heavy-duty diesel engine oil for up to 50,000 mile drain intervals. 15w40 has been the most common viscosity for Diesel motor oils used in on highway 18 wheeler trucks. It provides a good high temperature protection but one of the drawbacks has been the 15W40 makes the engine harder to crank when the engine is cold, so a thinner viscosity oil is recommended. Royal has developed a new synthetic 5W40 and 10W30 CJ-4 specification oils to meet these new requirements. One of the major benefits of using the new Monarch Diesel Ultra Syn P is the improved fuel economy. Thinner oils reduce drag and can help boost fuel economy from 1% to 5%, and can produce significant fuel savings over time.
