What statement is true on the difference between synthetic and conventional oil?

• Synthetic oil is a worse oil because it can cause your engine to lock up and seize.

• Synthetic oil helps your engine by keeping your engine cleaner, flows smoother in colder temperatures, and greater wear protection

• Conventional oils help your engine by creating less carbon emissions than synthetic oils. It also is cleaner so it helps your engine run smoother.

• Conventional oil is way much better than synthetic oil because it comes from the ground which means it is thicker making the engine run smoother for a longer period of time.
