Which Type of Engine Oil is Suitable for Turbocharged Engines?
2 Answers
For turbocharged models, it is recommended to use fully synthetic engine oil. Additional Information: 1. The construction of turbocharged engines imposes higher demands on the engine, as their internal components must withstand high temperatures and more severe impacts, compression, and other working conditions. Therefore, when selecting engine oil for turbocharged cars, it must have good anti-wear properties and also be resistant to high temperatures. Fully synthetic or semi-synthetic engine oils can precisely meet these requirements. Besides using the manufacturer-recommended oil, fully synthetic and semi-synthetic oils are both excellent choices. 2. The turbocharger is one of the most vulnerable components in a turbocharged engine. According to relevant data, more than 80% of turbocharger failures are due to insufficient lubrication from the engine oil. Hence, fully synthetic engine oil is currently the most suitable choice for turbocharged engines.
I've been using turbocharged cars for many years and know that improper oil selection can cause turbo overheating and damage. Turbocharged engines operate under high temperature and pressure, where conventional mineral oil tends to carbonize and clog. It's recommended to choose full synthetic oils like 5W-30 or 0W-40, which balance cold-start performance and high-temperature protection. API specifications such as SP or SN Plus are ideal, as they prevent turbo bearing wear. I change the oil every 5,000 kilometers, using brands like Mobil or Shell, and maintain moderate RPMs while driving to avoid extreme conditions. This protects the turbo's lifespan and improves fuel efficiency. Additionally, regular oil level checks are crucial—replace the oil immediately if it turns black or thin to prevent unexpected failures. In short, don’t skimp on low-quality oil, and always consult professional repair shops for advice.
