What Type of Oil Should a Turbocharged Engine Use?
2 Answers
Turbocharged engines should use fully synthetic oil. More information about automotive engine oil is as follows: 1. There are three types of engine oil for vehicles: mineral oil, semi-synthetic oil, and fully synthetic oil. These three types of oil differ in their service intervals and performance. 2. The service interval for mineral oil is 5,000 kilometers; for semi-synthetic oil, it is 6,500 kilometers; and for fully synthetic oil, it is 10,000 kilometers. 3. Fully synthetic oil offers superior high-temperature performance, ensuring better engine protection even when the vehicle is driven in harsh conditions.
I've been driving turbocharged cars for over a decade and have used several types of engine oil. Turbo engines operate at high temperatures, and conventional mineral oil can't handle it—fully synthetic oil is the best choice. I use 5W-40 viscosity oil, which ensures smooth cold starts and provides excellent high-temperature protection. It's crucial to choose oil with turbo-specific certifications, like ACEA A3/B4, which works well. Remember to check the oil condition every 8,000 kilometers, and if you frequently drive in high-temperature environments, change it earlier. Last time, I tried saving money with regular oil, and the turbo bearing wore out, costing me over 3,000 in repairs. Oil cleanliness is also important—poor-quality oil can cause carbon buildup in the intake, leading to noticeable hesitation during acceleration. Choosing the right oil can double the turbo's lifespan—this is not an area to cut corners.
