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.
One real concern is a very high mileage car that has used conventional oil going to synthetic. In that case,the synthetic oil might dissolve too much gunk, so it is recommended that you make the transition with 2 oil changes at 2K miles each so as to flush out the gunk.
