What kind of engine oil should be used for turbocharged engines?
2 Answers
Turbocharged engines should use fully synthetic engine oil. The function of a turbocharger is to increase air intake by compressing air, utilizing the inertial impact force of exhaust gases from the engine to drive the turbine in the turbine chamber. The turbine drives the coaxial impeller, which pressurizes the air delivered through the air filter pipeline, forcing it into the cylinders. The steps for changing the engine oil are: 1. Lift the car, remove the protective plate, and place a container of about 10 liters under the oil drain screw; 2. Unscrew the oil drain screw, use an air gun to blow for two minutes at the oil filler port, tighten the oil drain screw after draining, and wipe it with a tissue to check for leaks; 3. Reinstall the protective plate, lower the car, and use a funnel to add engine oil at the oil filler port.
From my decades of experience driving turbocharged cars, I can tell you that turbo engines require full synthetic oil because it can withstand the high temperatures of the turbo and protect critical components. Conventional oil tends to burn and cause carbon buildup and damage. I always use full synthetic oil with a viscosity of 5W-30 or 5W-40, depending on what your car's manual recommends. Don't skimp on this—if the oil isn't suitable, the turbo bearings will wear excessively, shortening the engine's lifespan. I make it a habit to check the oil level every 5,000 km to ensure it hasn't discolored or thinned. Follow the manufacturer's recommended oil change intervals, usually every 8,000–10,000 km. When changing oil, it's best to go to a trusted shop—they know cars and won't use the wrong oil.
