Does Mixing Two Types of Engine Oil Affect the Engine?

[VanWillow]

Mixing two types of engine oil for a long time can affect the engine. Here are the specific details about car refueling: 1. Gasoline grade explanation: Although high-grade gasoline has better anti-knock performance and power, vehicles designed for low-grade gasoline should not blindly use high-grade gasoline. Higher grades are more suitable for engines with larger compression ratios, while engines designed for low-grade gasoline usually have smaller compression ratios. Using high-grade gasoline may increase knocking in the engine. 2. Avoid mixing: Different grades of gasoline should not be mixed, such as mixing 98 and 95 gasoline. Long-term use may have certain effects on the engine, and may even lead to phenomena such as engine carbon deposits and increased fuel consumption.
