FAQ:

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

A: The answer is NO. It is not safe to use 5W20 in an engine that has 5W30 grade recommendation. As both the oils are 5W, they both have the same viscosity at room temperature or when the engine is not running.

Q: Is 5W – 20 synthetic?

A: Product Description. Mobil 1™ 5W-20 is an advanced full synthetic engine oil designed to keep your engine running like new by providing exceptional wear protection, cleaning power and overall performance. Mobil 1 5W-20 meets or exceeds the requirements of the industry’s toughest standards and outperforms conventional oils.

Q: What is conventional engine oil?

A: Conventional Oil. Conventional motor oil is made from refined crude oil. Other additives are mixed within the final product to increase the performance of the oil within an engine. However, the consensus is that conventional motor oil needs to be changed more frequently.
