What kind of engine oil should be used for German car maintenance?
2 Answers
German car maintenance recommends using Castrol brand fully synthetic engine oil. Higher requirements for engine oil: German cars have higher requirements for engine oil. German cars include Volkswagen, Mercedes-Benz, BMW, etc. German cars generally have high internal engine working pressure and high temperature, so they have higher requirements for engine oil. Viscosity requirements: Most German cars require a viscosity of 5w-30 or 5w-40, and most German cars require a viscosity of 30 or above. 0W, 5W, 10W, 15W, 20W, 25W, the symbol W represents winter. The smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature; 20, 30, 40, 50, the larger the number, the higher the viscosity, and the higher the applicable maximum temperature.
I've been driving German cars for over a decade, like BMW and Audi, and the engine oil used during maintenance is particularly crucial. Manufacturers usually recommend fully synthetic oil with viscosities such as 5W-30 or 0W-40, which ensures quick cold starts in winter and protects the engine during high summer temperatures. From my experience, using top brands like Castrol or Mobil that meet the VW 502.00 standard is essential—never opt for cheap, low-quality products, as they can lead to severe engine wear and costly repairs. Regular oil changes are vital; check every 5,000 to 7,500 kilometers, along with inspecting the air filter. Maintain the oil level properly—avoid overfilling, which affects performance, or underfilling, which causes overheating. Remember, high-quality oil extends engine life and saves fuel costs. Once you develop the habit, your car runs smoother, ensuring safe and worry-free driving.
