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.
Your owner's manual should have both mileage and time based recommendations for your particular vehicle. Follow that, whatever it happens to be. Oh - if your engine is not designed for use of synthetic oil. using synthetic doesn't magically extend the oil change interval.
