What does the manufacturer recommend for my vehicle?
Castrol always recommends following the guidelines of the manufacturer for the recommended GRADE and API specific to your application. This information can be found in the vehicles owner’s manual, by contacting the manufacturer directly, or by visiting the Castrol Grade Calculator at: http://www.castrol.com/castrol/LubesSelector.do?categoryId=82915691
While a certain grade of oil may be suitable for one vehicle, it does not mean it is best for your vehicle. The GRADE of oil depends on the vehicles engine design, and the GRADE recommended by the vehicle manufacturer is the BEST for your specific vehicle.
Also, by deviating from the grade recommended you could potentially void your manufacturer’s warranty.
