What Type of Engine Oil is Suitable for Summer?
2 Answers
In summer, it is recommended to use engine oil with viscosity grades such as 10W40 or 10W30. Under the condition of ensuring lubrication, you can choose engine oil with lower viscosity based on the temperature range during use, engine temperature, and actual vehicle condition. For engines in good condition with minimal wear, you may opt for lower viscosity oils like 5W30 or 10W30. For engines with severe wear and larger clearances, it is advisable to use higher viscosity oil such as 10W40. Key considerations when adding engine oil include: 1. Always select the oil grade specified in the vehicle's user manual; 2. Determine the appropriate oil based on the vehicle's age, engine condition, and regional climate; 3. The amount of oil added should be slightly below the standard mark.
Driving in summer heat causes the engine temperature to rise quickly, so it's crucial to choose the right oil grade to prevent thinning and insufficient lubrication. Based on my experience, the most commonly used grades are SAE 5W-30 or 10W-40. The former is suitable for all seasons including summer, while the latter provides better engine protection in high-temperature regions to avoid overheating and wear. Avoid using overly thin oils like 5W-20 as they accelerate engine wear in summer. Regularly check the oil level—inspect every 1,000 km and replace it promptly. It's recommended to change the oil every 5,000 km or every six months to ensure stable oil film performance. Opt for full synthetic oil for better durability, fuel efficiency, and environmental friendliness. If you drive an SUV or frequently take long trips, consider increasing the viscosity to 10W-40. Always refer to the manual—never arbitrarily change the oil grade, whether for new or old cars—safety comes first. Bonus tip: Pair oil changes with a quality oil filter to extend engine life, save money, and drive farther with peace of mind.
