Diesel Engines And Premium Synthetic Oils

Imperial, California (NAPSI) - It’s a new day for diesel engines. That’s the  word from experts who say improvements in diesel technology and fuel  composition have made diesel vehicles more appealing to a broader group of  consumers.

Because of these improvements, people who choose diesel vehicles report  better gas mileage and increased torque. Plus, diesel vehicles typically hold  their value in the resale market better than those with gasoline-powered  engines.

While in the past many thought that you could not use a  synthetic oil in a diesel engine, that is not the case. Today’s  diesel vehicles can benefit from the same improvements in performance and  protection that a premium synthetic motor oil, such  as Royal Purple, offers gas-powered vehicles.

Common Questions

To help, here are some answers to common questions about using a synthetic oil in a diesel vehicle.

• Is it possible to run synthetic for one oil change and then switch  back to mineral oil? Yes. Most synthetic oils including Royal Purple are  compatible with other mineral and synthetic oils. You will want to check the  label on the manufacturer’s bottle for confirmation.

• What is the difference  between 5W-40 and 15W-40 for diesel engines? Assuming they are American  Petroleum Institute (API) licensed (CI-4, CJ-4, etc.),  both are effective SAE 40 weight oils. As the oil cools from engine operating  temperature, the 5W-40 will thicken less than the 15W-40. The smaller the  first number of the viscosity, the better the fluid flows when cold.

Depending on the age of your engine, older diesel engines may see a slight  increase in oil consumption with lighter oil.

• Do you need to adjust the  viscosity of your oil based on where you live? Sometimes. The way you use  your vehicle is also a factor. In general, many auto manufacturers recommend  an “all temperature” viscosity. Your owner’s manual will  indicate which “all temperature” oil is recommended for your  vehicle and location.

• What about premium oil  filters? It’s a good idea to use a premium oil filter in tandem  with a synthetic oil. Oil filters prevent  contaminants from circulating through the system, causing damage. Premium oil  filters offer superior filtration media and internal and structural  components made of high-quality material.

If you’re considering purchasing a diesel vehicle, don’t  forget that maintaining the vehicle is key.
