What is the suitable engine oil for the Golf 1.4T?
2 Answers
The Golf 1.4T uses the original semi-synthetic engine oil with the specification of 5W-40. Below are the relevant details about semi-synthetic engine oil: 1. Introduction: Semi-synthetic engine oil is a lubricant formulated from Group III base oils, which are refined from mineral oil through hydro-cracking technology. Specifically, it is made by blending mineral oil and full synthetic oil in a ratio of 4:6, along with the addition of certain additives. 2. Application Scope: Semi-synthetic engine oil is generally suitable for mid-to-low-end naturally aspirated engine models. As long as it is not a turbocharged engine or a high-end, large SUV model, semi-synthetic engine oil can be used. The replacement cycle for semi-synthetic engine oil is around 8 months, typically requiring replacement after approximately 7,000 kilometers.
My Golf 1.4T has been running for 6 years, and the manual clearly states: It must use fully synthetic oil that meets the Volkswagen VW502 standard. Turbo engines operate at high temperatures, and regular oil can't handle it. Either 5W-30 or 5W-40 is fine, but I prefer the latter in summer. Last time during maintenance, the mechanic said that for German cars, you also need to check the certification number. Just look for the VW502 or 504 label on the oil container. Don’t exceed the oil change interval of 10,000 km, and check the oil level frequently, as turbo engines tend to burn oil. Don’t trust the no-name oils randomly recommended online. The original oil from the 4S shop might be a bit more expensive, but it’s worry-free. If you change the oil yourself, remember to prepare an 8mm hex wrench. The drain plug is at the lower left of the oil pan, and the used oil must be recycled separately.
