German oil, additive and car care specialist LIQUI MOLY has introduced new TopTec Truck 6150 5W-30 oil which meets the latest approval as per DTFR 15C130 from Daimler Truck.

Car and commercial vehicle engines share the trend towards even thinner oils. Around ten years ago, 10W-40 was still used as the standard viscosity in a truck but now Euro V and VI engines are filled with a 5W-30 lubricant. 

"Engine oil has transitioned from a mere operating fluid into a liquid component," explains Klaus Stahl, Sales Manager of the Commercial Vehicles Division at LIQUI MOLY. He adds, “Oils, such as the new Toptec Truck 6150 5W-30, are developed to perfectly match new engine generations. This also increasingly leads to the new lubricant not being backwards compatible. It must therefore not be used in vehicles with older engines, as damage cannot be ruled out as a result of the low viscosity," 

Klaus also points out that "A 5W-30 lubricant like our new Toptec Truck 6150 offers an excellent combination of low viscosity and low wear. In other words, the cost-benefit ratio is very good." 

Like in cars, in CVs it is not the viscosity that is the benchmark, but the approval of the vehicle manufacturer. Reflecting this LIQUI MOLY has a digital oil guide and a technical hotline safely guide.

TopTec Truck 6150 5W-30  is now available from LIQUI MOLY stockists.
