Is 0W or 5W engine oil better?
1 Answers
0W engine oil has higher quality requirements. Here is the relevant introduction to the selection method of engine oil: 1. Principle: The selection of engine oil is very particular. Car owners can choose engine oil based on the local highest and lowest temperatures, the grade of the vehicle, and the condition of the vehicle; 2. Differences between different engine oils: If engine oil with too high viscosity is selected, it will increase movement resistance and affect engine power; If engine oil with too low viscosity is selected, it cannot guarantee lubrication quality and will aggravate engine wear; 3. How to choose: For engines that are already severely worn and have larger clearances, a higher viscosity grade of engine oil can be selected to enhance the sealing performance of the components. Simply put, new cars are better suited for thinner engine oil, while cars with higher mileage are better suited for thicker engine oil.
