Mastering Engine Lubrication 5W-40 vs 5W-30 – The Essential Comparison

Oil viscosity explained: It's the measure of oil's resistance to flow, affecting lubrication, reducing friction, and ensuring optimal engine performance. Coming back to the example of 5W-30, where 5W denotes the viscosity, the '30' determines the thickness of the oil at a temperature of 100 ... Excess amounts of oil consumed by an engine burning it can be addressed by using a thicker oil, a 10W-40 might not burn off as fast compared to ... El consumo al que se refiere casi seguro que es el del aceite por bajar viscosidad. Sí con 5W30 te gasta algo, te recomiendan subir a 5W40. Thought I would share my recent experience of switching engine oil to more viscous 5w40 from 5w30. Car is Fabia VRS 130 PD using 505.01 PD ... The 5 is the same. The 40 is higher viscosity at operating temps, compared to 30. The engine was designed for 5w30. 5w30 is thinner than 5w40 at 100c and 40c. 2. 0w30 has lower viscosity at 40c than 5w30 3. 0w40 has lower viscosity than 5w40 at 40c. 5w40 offers thicker, high-temperature protection for hot areas, while 5w30 flows better for colder climates and improves fuel mileage. For high mileage engines, ...
