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.
How often should a car's synthetic oil be changed? A: Synthetic car oil needs to be changed after 10,000 to 20,000 miles, depending on the climate and driving distances. The recommended non-synthetic oil change is every 3 months or 3,000 miles, whichever comes first. However, synthetic oils, which cost nearly twice as much as conventional oils, require less time between changes because of their ability to withstand high temperature levels.
