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.
So while yes, I have revised my thinking regarding extending oil change intervals: Here are my revised oil change recommendations: change regular petroleum based oils every 4-5 thousand miles and synthetic every 5-7 thousand miles.
