FAQ:

Q: Is 5W20 better than 5W30?

A: Yes, a lower viscosity oil like 5w20 will provide less protection than 5w30 in normal operating conditions. However, a lower viscosity oil is better in areas of the country with lower average temperatures and below freezing conditions.

Q: What is the difference between 5W30 and 5W20?

A: The key difference between 5W20 and 5W30 motor oil is that the former is thicker or less viscous. When you pour it into engine, 5W20 oil will create less friction owing to its thinner viscosity , which means it results in less drag throughout the engine parts, such as pistons , valve train, and crankshaft.

Q: Can I use 10W30 instead of 5W20?

A: When 10w30 is used instead of 5w20, probably, only a few changes are discoverable especially when the engine is about to wear out and is old. Moreover, one of the benefits of thinner oil would be to ignite quickly. Therefore, fewer efforts are required to pump the fuel, which minimizes the fuel economy.

Q: What is the difference between 5W – 20 and 5W – 30 motor oil?

A: The main difference between 5W-30 and 5W-20 motor oil is that the latter is less viscous (or thick). When used in a vehicle’s engine, 5W-20 oil creates less friction due to its thinner viscosity , meaning it causes less drag across engine parts like the crankshaft, valvetrain , and pistons.
