What does 5w40 mean in engine oil?
5w40 motor oil has a winter viscosity grade of five, meaning it's less viscous at very low temperatures, compared to, say, 10w40. It has a hot viscosity grade of 40, which means it is just as viscous as 10w40 at high temperatures but less viscous than oils such as 15w50.
Is 5w40 good for diesel engines?
One engine oil for mixed fleet operations
Mobil 1 Turbo Diesel Truck 5W-40 engine oil is recommended for use in all super-high-performance diesel applications, including modern low-emission engine designs with Exhaust Gas Recirculation (EGR).
What oil is thicker than 5w30?
10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil.
