Should the Touareg use 5w40 or 0w40 engine oil?
3 Answers
The Touareg can use either 5w40 or 0w40 engine oil. These two types of oil have the same viscosity, but differ in low-temperature flow performance. Below are the specific differences in low-temperature flow between the two oils: 1. 5w oil can flow normally at temperatures as low as -30 degrees Celsius. 2. 0w oil can flow normally at temperatures as low as -35 degrees Celsius. Here is more information about engine oil: 1. Engine oil is referred to as the lifeblood of the engine. Without oil, the engine cannot operate properly. 2. In the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat.
I've been driving my Touareg for almost five years, always using 5w40 oil. The manual recommends the VW 50200 standard, and I've had no issues using synthetic oils from Mobil or Shell. For daily commuting, 5w40 is more cost-effective with decent fuel consumption control. However, last month when I traveled to Northeast China, a friend suggested switching to 0w40, claiming it provides much faster cold starts. The engine indeed runs smoother with less noise in cold conditions, making it more suitable for regions with significant temperature variations. I typically change the oil every 8,000 to 10,000 kilometers to avoid carbon buildup. I make it a habit to check the oil level myself using the dedicated dipstick, ensuring no mixing with oils of different viscosities. Overall, choose based on climate and personal preference—there's no strict need to switch to 0w40, but don't skimp on maintenance to save a few bucks.
As a mechanic who has worked on numerous Touaregs, I must say either 0w40 or 5w40 engine oil is acceptable, but the key is to consult the manual. New turbocharged engines typically recommend 0w40 due to its superior low-temperature fluidity for better component protection, while 5w40 is more common for older models. The number before W indicates cold-weather performance (0w excels in extreme cold), and 40 after W represents high-temperature viscosity. I've encountered owners using incorrect oil, leading to unstable oil pressure or warning lights – requiring immediate troubleshooting. I recommend synthetic oils like Castrol that meet VW standard 50400. Climate also matters: 0w40 ensures quicker cold starts in northern winters, while 5w40 suffices in southern regions. Never neglect regular oil and filter changes – this extends engine life and ensures worry-free driving.
