What Type of Engine Oil Should Be Used in Summer?

[DelRylee]

In summer, it is generally recommended to use engine oil with specifications such as 10W40 or 10W30. The oil bottle will clearly indicate the oil type. During summer use, while ensuring proper lubrication, it is advisable to choose engine oil with lower viscosity based on the temperature range, engine temperature, and actual vehicle condition. For engines in good condition with minimal wear, lower viscosity oils such as 5W30 or 10W30 can be selected. For engines with significant wear and larger clearances, slightly higher viscosity oils like 10W40 may be more appropriate. The amount of oil added should be slightly below the standard mark, as excessive oil can increase the crankshaft's rotational resistance and reduce the engine's output power.
