Is Mobil Oil SP Grade Higher Than SN Grade?

[KalebFitz]

The differences between Mobil Oil SP and SN are as follows: 1. Difference One: Compared to SN, the biggest difference with SP is that SP has requirements for low-speed pre-ignition and timing chain wear, which can solve low-speed pre-ignition issues in TGDI small-displacement turbocharged direct injection models. Other differences include the use of new engine models in bench simulation tests. Overall, SP offers better comprehensive performance. 2. Difference Two: China VI vehicles are divided into two categories: those with particulate filters and those without. Vehicles with particulate filters require low-ash oil, but SP does not have ash content requirements. Therefore, SP oil can be either high-ash or low-ash. As a result, most manufacturers recommend European standard ACEA C series oils with low-ash requirements for vehicles equipped with particulate filters. However, the overall performance requirements of ACEA C series oils are higher than those of SP, making the cost of using this series of oils relatively high for some mid- to low-end models. This leads to a situation where SP does not have low-ash requirements.
