What type of engine oil is suitable for the Golf 1.4T?
1 Answers
Golf 1.4T requires fully synthetic engine oil with a specification of 5W-40. Relevant details are as follows: 1. Reason: The Golf 1.4T engine is a turbocharged direct-injection engine. Due to the high demands of turbocharging, fully synthetic oil is necessary. Fully synthetic oil offers strong oxidation resistance and is less prone to contamination. In contrast, conventional mineral oil is more susceptible to contamination under high temperatures and has weaker oxidation resistance. 2. Importance of engine oil: Engine oil is a critical factor affecting engine performance and lifespan, so it is essential to use the correct specification. The quality of engine oil must meet the requirements of both the engine and exhaust purification system, and it must also be compatible with fuel quality. This is because engine oil continuously interacts with combustion residues and fuel during operation, accelerating the aging process of the oil.
