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.
While synthetic generally holds up better and can serve for more miles, it is important to not extend oil changes beyond the time interval recommended by the manufacturerâtypically six months or a year. Another good use for synthetic oil is as a salve for older engines prone to sludge buildup. This gunky residue can block oil passages and lead to a quick death of an engine. In the early 2000s, several engines from Chrysler, Toyota, and Volkswagen, among others, were especially prone to sludge buildup.
