What Vehicles Are Suitable for 15W50 Engine Oil?

[IsaacAnn]

15W50 engine oil is suitable for vehicles with high mileage and significant wear, as the increased clearance between pistons and cylinders requires higher viscosity oil to maintain proper oil film thickness for lubrication. If the viscosity is too low, the oil may leak into the combustion chamber, leading to oil burning. Below are specific considerations for using engine oil: Selecting Based on Engine Requirements: Choose engine oil according to the engine's specifications. Using overly advanced oil in engines with lower requirements is unnecessary, and lower-grade oil should not be used in high-performance engines. Preference for Multi-Grade Oil: Multi-grade oil is recommended due to its cost-effectiveness, longevity, and efficiency in protecting the engine. Due to its properties, multi-grade oil may appear darker earlier or exhibit lower oil pressure compared to conventional oil, which is normal. Seasonal Considerations: For engines in good condition during colder seasons, lower viscosity oil is preferable for smoother oil flow. In high-temperature conditions or for severely worn engines, higher viscosity oil helps form a protective oil film and reduces engine wear.
