What are the reasons for changing Fuchs engine oil?

The reason for changing Fuchs engine oil is to ensure the normal function of the oil and effectively protect the engine. Functions of engine oil: Between the engine piston and cylinder, as well as between the main shaft and bearing bush, relative sliding causes wear. The oil cools and reduces temperature by carrying heat back to the oil tank and then dissipating it into the air, assisting the radiator in cooling the engine. It forms a thick oil film between two sliding surfaces to separate the surfaces of relatively sliding parts and reduce wear. Shock absorption and cushioning: When the pressure at the engine cylinder port increases, it suddenly intensifies the load on the piston, piston pin, connecting rod, and crankshaft bearings. The load is transmitted through the bearings, and lubrication cushions the impact load.
Last time I switched to Fuchs oil, I noticed a much smoother cold start. Before, the engine would rattle when starting in winter, but now it's barely audible. This oil really has strong low-temperature fluidity, quickly reaching every part in the morning. It's also stable at high speeds—previously, the engine would struggle past 3000 RPM, but now it feels confident even at 4000 RPM. Most importantly, its cleaning performance is outstanding. During the last maintenance, when the oil pan was removed, carbon deposits were nearly half compared to using regular oil. The mechanic even said this oil is particularly friendly to turbocharged engines. Although it costs about a hundred bucks more per change, the maintenance interval can be extended by 30%, making it more cost-effective in the long run.
My friends who drive German cars all use Fuchs, so I decided to give it a try. The most noticeable improvement was in fuel consumption—it dropped by 0.8 liters per 100 km during city commuting. The mechanic said this is due to its optimized friction coefficient, which reduces piston movement resistance. Another pleasant surprise was faster air conditioning cooling. The technician explained that oil performance affects water pump efficiency, indirectly impacting the entire cooling system. Remember to choose the right viscosity grade—my old Tiguan uses 5W-40, and for new cars, it's best to refer to the manual rather than adding randomly. Also, be careful not to buy counterfeit products—authentic bottles have anti-counterfeit codes that can be verified three times.
