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.
The safest course of action is, of course, to use the synthetic oil your engine manufacturer recommends, even if it costs more, doubly true if your engine is under warranty. But synthetic oils need not be your default choice. As long as your engine is out of warranty, you may get perfectly adequate protection from conventional oil, as long as you choose the right one and follow proper change recommendations.
