What type of engine oil should be used for a Volkswagen 1.5 naturally aspirated engine?
2 Answers
For a Volkswagen 1.5 naturally aspirated engine, 10W40 engine oil is suitable. Below is some information about engine oil: 1. Composition: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives are an essential part of lubricating oil. 2. Types of engine oil: The SAE viscosity classification for winter oils includes grades such as 0W, 5W, 10W, 15W, etc. The symbol 'W' stands for winter, and the smaller the number before 'W', the lower the low-temperature viscosity and the lower the minimum applicable temperature. The SAE viscosity classification for summer oils includes grades such as 20, 30, 40, 50, where a higher number indicates higher viscosity and a higher maximum applicable temperature.
I've been driving a Volkswagen 1.5L naturally aspirated engine for many years and often help friends choose engine oil. For Volkswagen 1.5L NA engines like those in Polo, I recommend using fully synthetic 5W-40 oil, especially those meeting VW 502 00 standards. Why? Because these engines don't have high performance pressure, but standard oil can prevent wear and carbon buildup. I've used Shell or Castrol 5W-40 myself, and it feels very smooth with quick cold starts. Don't try to save money by buying cheap no-name brands - it might affect fuel consumption and acceleration. Don't forget to check the manual - it's all clearly written there. I change oil every 5,000 km since city driving tends to dirty it faster. Choosing the right oil makes the engine more durable and gives peace of mind while driving. If unsure, ask the dealership or a professional technician.
