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.
Although most people still have the oil in their car changed every 3,000 miles, most experts suggest that synthetic oil only needs to be changed after 5,000 to 7,500 miles. However, some manufacturers list oil change intervals as high as 10,000 or even 15,000 miles when using synthetic oil.
