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.
Synthetic Oil will be about double the cost of High Mileage Oil on a 15,000 mile Oil Change basis. Be careful, the first usage of SYNTHETIC Oil in older cars, often consumes some oil when using SAE 5W-30, 10W-30 or 20W-40 SYNTHETIC viscosities. Source(s): Licensed CA smog inspector.
