What is 10w 40 engine oil? 10W-40 is the viscosity, or weight, of the motor oil as defined by the Society of Automotive Engineers (SAE for short). A 10W-40 oil has a viscosity grade of 10W at a low temperature and 40 at a higher temperature. What does this mean, exactly? Motor oil thickens when it’s cold and becomes thinner when heated up.
What is 10W-40 oil? The lower the “W” number the better the oil’s cold temperature/cold start performance. The 40 in a 10w-40 simply means that the oil must fall within certain viscosity limits at 100°C. … Once again the lower the number, the thinner the oil: a 30 oil is thinner than a 40 oil at 100°C etc.
When should I use 10W40 oil? While both are low-temperature grade oils, 10W40 is thicker at high temperature; therefore, better to use in warm weather.
Is 10W40 better than 5w30? The first number in the motor oil’s name describes the oil’s cold viscosity. … A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
