What kind of engine oil should be used for turbocharged cars?
4 Answers
Turbocharged cars should use fully synthetic engine oil. The steps for changing the engine oil are: 1. Lift the car, remove the protective plate, and place a container under the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow for two minutes at the oil filler port, then tighten the oil drain plug and wipe it with a tissue to check for oil leaks; 3. Reinstall the protective plate, lower the car, and use a funnel to add engine oil through the oil filler port. The working principle of a turbocharger is: using the exhaust gas from the engine's exhaust port as power to drive the turbine in the turbine chamber, which is directly connected to the supercharger wheel in the supercharger chamber. One end of the supercharger chamber is connected to the air filter, and the other end compresses the air drawn from the air filter into the engine's cylinders to increase the amount of air in the engine.
I've been driving turbocharged cars for several years and have learned a lot of experience. Turbocharged engines run at extremely high temperatures, and conventional engine oil simply can't withstand the heat, easily burning out or deteriorating. That's why I only use full synthetic oil, with a viscosity of 5W-40 or 0W-40 being the most suitable. Using 40 viscosity in summer provides better lubrication. I've had good results with Mobil 1; the engine runs quietly and stably. Change the oil every 8,000 kilometers or so, and don't exceed the limit. Using the wrong oil, such as mineral oil, can cause turbo carbon buildup or damage, increasing repair costs by thousands. Also, pay attention to the oil brand; avoid no-name brands and check reviews to choose reliable ones. Regularly checking the oil dipstick is also important to detect abnormal consumption in time and ensure the car's long-term health. Proper maintenance can even lead to lower fuel consumption.
I've been using turbocharged cars for many years and prioritize cost-effectiveness and performance when selecting engine oil. Turbos operate at high temperatures, where regular oil's lubrication performance deteriorates, accelerating engine wear. I recommend prioritizing full synthetic oil, with viscosities like 5W-30 or 0W-40, adjusting according to the season—lower viscosity is better in winter. I usually use Castrol full synthetic oil, which offers good protection at a reasonable price. Keep the oil change interval between 6,000 to 7,500 kilometers—don’t cut corners on costs. Using cheap mineral oil may save money short-term but can lead to turbo failures long-term, such as oil line blockages, which can be costly to repair. Also, adjust based on driving habits—if you frequently drive on highways, ensure stable oil pressure. Always opt for reputable brands when purchasing—don’t risk safety for small savings.
Having repaired cars for over a decade, I've frequently encountered issues with wrong oil selection in turbocharged vehicles. Full synthetic oil is mandatory to maintain lubrication stability under high temperatures and prevent turbocharger overheating damage. Recommended viscosity is 5W-40, suitable for most road conditions - avoid mineral oils that easily carbonize and cause blockages. I advise oil changes every 7,000 kilometers using premium brands like Mobil or Shell for better protection. Neglecting this will significantly shorten turbocharger lifespan.
