FAQ:

Q: What is the difference between 5W20 and 0W20?

A: Both 5w-20 and 0w-20 are IDENTICAL once the car is up to temperature. The difference is how thin those oils are when the car is cold. Neither the 0w or the 5w flow enough in the cold to properly lubricate your engine. However, the 0W is thinner and does LESS damage at start up than the 5W oil.

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

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 all 5W20 oil synthetic?

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 is full synthetic oil?

A: Synthetic Oil. Synthetic or “full synthetic” oil is engineered specifically to provide the highest level of lubrication in high and low temperatures, which results in better overall engine protection. Synthetic oil has superior cleansing properties which help to keep your engine cleaner. While it is the most expensive type of motor oil,…
