VW50400 is a high-end long-life engine oil. Here are some considerations when purchasing engine oil: 1. Suitable for the engine: Choose engine oil based on the engine's requirements. It's unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. 2. Multi-grade oil protection: It's advisable to opt for multi-grade oil, which offers savings, long service life, and high efficiency, providing better protection for the engine. Due to the characteristics of multi-grade oil, phenomena such as premature darkening and lower oil pressure compared to conventional oil may occur during use, both of which are normal.

I'm an experienced driver and have been driving Volkswagen cars for many years. VW50400 is one of Volkswagen's oil specification numbers, specifically designed for gasoline engine vehicles like the Passat or Golf I drive - it's always marked in the manual. The advantage of this standard is that it allows the oil to last longer between changes, typically 20,000 kilometers or two years, saving me frequent trips to the repair shop. When selecting oil, I always look for the 'VW 504 00' label on the bottle. Using oils with other standards might cause problems like noisy engines or even skyrocketing fuel consumption. I always insist on using this oil during maintenance - it protects components and extends the vehicle's lifespan. It's simple, practical and reassuring. Never underestimate this suggestion in the manual, as it's one of the key maintenance secrets.

What causes the shock absorber noise in Mercedes-Benz E-Class?

Due to the structure of the shock absorbers in Mercedes-Benz E-Class vehicles, the entire shock absorber gets compressed when the vehicle passes over bumpy roads, thereby compressing the external spring. However, after the vehicle passes the bumpy section, the spring's elasticity causes the shock absorber to reset. During this compression and reset process of the shock absorber, a "hissing" or "whooshing" exhaust sound may accompany the movement. Here is some relevant information: Normal condition: Therefore, there's no need to panic when you hear "hissing" or "whooshing" sounds from the shock absorbers while driving on bumpy roads—these are normal occurrences. Mercedes-Benz E-Class shock absorbers: Every vehicle must bear the weight of the vehicle itself and its passengers while also reducing road bumps during this process.
