However, it's important to note that the specific viscosity requirements may vary depending on the model year and any modifications made to the engine. To ensure the best performance and longevity of your engine, I recommend referring to the owner's manual or consulting with a certified mechanic for the most accurate information. They will have the expertise to guide you on the appropriate oil viscosity based on your engine's specific requirements.
