Molecules in the gas state move much faster than their liquid or solid states. Depending on the temperature and pressure, molecules can exist in three states: gas, liquid, o â¦ r solid. At high temperatures and low pressures, the gas state is favored.
I have been told that if you start using synthetic lube oil, you must continue. Going back to regular oil will damage the engine. That does not make sense to me.
Our recommendation: 1  It is best to follow the maintenance schedule provided by the manufacturer (you can check your schedule in your YourMechanic profile). 2  We recommend replacing the oil and filter every 5,000 miles or four months. 3  Synthetic oil (versus regular) is cost effective.
