What type of engine oil should be used for the Volkswagen Golf 1.4T?
2 Answers
You can use the original semi-synthetic engine oil with a specification of 5W-40, but it is best to use fully synthetic engine oil. The relevant details are as follows: 1. Due to the high working power of the Volkswagen Golf's engine, the internal temperature of the engine becomes very high during operation. Therefore, using high-viscosity engine oil can protect the internal components of the engine, providing cooling and lubrication. Engine oil is a crucial factor affecting the engine's performance and lifespan. The vehicle is factory-filled with a special high-quality multi-grade viscosity oil, which can be used year-round except in extremely cold weather. 2. Like other components of the car, engine oil is also continuously evolving. Volkswagen authorized dealers are up-to-date with the latest developments and technical data of automotive fluids, so it is recommended to have the engine oil changed by a Volkswagen authorized dealer. 3. The quality of engine oil must not only meet the requirements of the engine and exhaust purification system but also match the fuel quality. Since the engine oil is constantly in contact with combustion residues and fuel during engine operation, this accelerates the aging process of the oil.
As a long-time car owner who frequently helps answer questions in car enthusiast groups, I recommend using 5W-40 oil that meets the VW 502 standard for the Volkswagen Golf 1.4T. This engine is quite particular about oil, and sticking to the factory requirements is the safest bet. For example, last year I switched to a well-known brand's full synthetic 5W-40 oil, and the engine noise at idle became noticeably quieter. It's crucial to avoid counterfeit products—during maintenance, it's best to supervise the entire process, as some small shops might secretly switch to cheaper oil. Remember to change the oil every 7,500 kilometers or so; the last time I exceeded it by 1,000 kilometers, and my fuel consumption shot up to over 9 liters per 100 km. If you frequently engage in aggressive driving, you might consider upgrading to 0W-40 oil for better high-temperature protection.
