FAQ:

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

A: The difference between 5W-30 and 5W-20 motor oil. 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 .

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

A: ​One of the advantages of using the 5w20 instead of the 5w30 oil is that the former provides better fuel efficiency. When the oil flows faster, the engine also ignites faster and therefore fuel is conserved. The efficiency, though significant, will not lead to an extremely noticeable jump on your MPG.

Q: Is 5W20 a synthetic oil?

A: Both 0W20 and 5W20 are low-viscosity and high-quality synthetic oils that can greatly optimize the fuel economy. When you use such advanced full-synthetic oil formulation, the engine also performs at its highest efficiency.

Q: What does 5W20 or 5W30 mean?

A: 5w20 is an engine oil type characterized by its winter rating of 5 and an oil weight of 20 in warmer conditions. It is less viscous compared to 5w30. 5w30 has the same viscosity rating of 5 during winter but an oil weight of 30 during hotter conditions hence it is thicker.
