Engine oil products that are suitable for icy temperatures
What does 10W-40 oil actually stand for? Engine oil can be classified according to various SAE viscosity classes for oil fluids, which provide information about the oil viscosity or "resistance to flow" (SAE stands for the Society of Automotive Engineers). Where motorists could only choose from single-grade oils for winter or summer in the past, multi-grade oils for all seasons now dominate the synthetic oil market. 10W-40 engine oil is one such multi-grade oil. The minimum temperature viscosity limit of this oil is -30 °C (meaning this performance oil is still pumpable at this temperature), while its minimum viscosity at 100 °C is 12.5 mm²/s. Top manufacturers like Castrol and Mobil offer a diverse range of 10W-40 engine oils. Mobil Super™ 2000 X1 10W-40 not only lubricates the engine, but keeps it clean even during cold starts. This oil product is suitable for many cars and vans with normal loads. Other engine oils in this class are Castrol Magnatec 10W-40 A3/B3 and Shell Helix HX6 10W-40 oil, which can also be used for turbochargers or multi-valve engines.
