10w30 is the better all-purpose motor oil between 10w30 and 10w40. Shell Helix Ultra. For use at low temperatures (between -20 and +20 degrees Celsius) use 5W-30 oil. Low Running Temperature Or Cold Weather As we already know, 10W-30 and 10W-40 have the same oil viscosity at lower temperatures .

10w40 oil is an oil weight, or viscosity, that is designed for use in high-performance cars. The oil is designed in a way that the fuel consumption is also minimized, increasing the fuel economy, which is due to the lubrication provided by the oil to the engine. 10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. Pick a high mileage oil and use it 5W-30, if you went to 10W-40 are you trying to fight consumtion? This is because it will load more in the crank in your engine.
