Mercedes Diesel Oil Change Kit 5W-30 - Liqui Moly 6421800009

Product Information

Over time, oil breaks down, collects dirt and debris, and loses its lubricating properties, making it ineffective. An oil change kit offers all the necessary components for replacing the old, dirty engine oil with fresh oil to properly lubricate the engine components. Symptoms include: dark or dirty oil, unusual engine noises like knocking, increased engine heat, reduced fuel efficiency, smoke from the exhaust, and often on newer models and maintenance warning lights.

• Dark or dirty oil: When you check the dipstick, if the oil appears black or very dark, it's likely time for an oil change.
• Engine knocking sounds: A knocking or tapping sound from the engine can indicate insufficient lubrication due to old oil.
• Increased engine temperature: Dirty oil is less efficient at dissipating heat, leading to higher engine temperatures

About Liqui Moly

All LIQUI MOLY products are created by close solidarity with the automotive, two-wheel and commercial vehicle industry. That's why Liqui Moly solutions are always on par with state-of-the-art technologies and sometimes even a good distance ahead. The recipes for LIQUI MOLY high-tech products are largely based on our own developments, that we continuously test and develop. The LIQUI MOLY full range, with more than 4,000 products, offers you lubricants, additives, car care products and chemical repair tools with integrated use guarantee.

LIQUI MOLY offers the matching motor oil for every vehicle in the world. Liqui Moly engine oils have a variety of approvals by German and overseas car manufacturers or fulfill the requirements of the producers. And, even here, there are still differences: A manufacturer approval means that the oil fulfills certain minimum requirements. But LIQUI MOLY goes beyond those requirements and develop oils that, for example, have a higher cleaning performance than what is required by the manufacturer.

Every mile driven costs a tiny bit of engine longevity. The reason: Friction and wear. A creeping process, that is often accelerated by poor fuel quality and deposits of old lubricants. However, regular maintenance of the oil and fuel circuit can usually restore engine performance to its original level. Without much effort, but with a great deal of effect. When it comes to gear oil a similar thing can be said.

The fact that LIQUI MOLY products shine, and, with a high level of innovation, deliver what they promise, is confirmed again and again by independent testing institutions, in which we regularly pass with flying colors. Approvals by the automotive industry and the fulfilling of the highest specifications are also a matter of course.
