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.
I guess I just know too much based on personal experience. Here are my revised oil change recommendations: Change regular petroleum-based oils every 4000 to 5000 miles and synthetic oils every 5000 to 7000 miles.
