Liqui Moly Top Tec 4100 5W-40 Synthetic Technology Based Engine Oil is a low-friction motor oil designed to optimize engine performance and efficiency. It provides robust wear protection, reduces both oil and fuel consumption, and ensures rapid oil circulation, even in challenging conditions. This oil is formulated with advanced synthetic technology that reduces internal friction in the engine, resulting in smoother performance and enhanced fuel efficiency over time. It is developed to minimize engine wear, contributing to the long-term durability of engine components, and supports extended service intervals of up to 30,000 km, depending on manufacturer guidelines. The oil offers high shear stability and is suitable for gasoline and diesel engines that meet the Euro 4, Euro 5, and Euro 6 emission standards, including common rail and pumped jet injection. It is also compatible with gas-driven vehicles (CNG/LPG) and vehicles with a diesel particulate filter (DPF), even if retrofitted. Tested for use with turbochargers and catalytic converters. Always follow the specifications and instructions from the unit or vehicle manufacturer. Optimum effect is achieved when the product is used unmixed.
