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.
Most cars now say in their owners manuals to change oil every 7500 miles, and that is regular oil not synthetic. I think for anyone that isn't changing oil often, because of time or whatever reason, they should use a good synthetic like Mobil1 and change it 12 months or 12000 miles max.
