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.
Any synthetic oil can go to about 5000 miles. Just keep in mind how much abuse you put your car through. If you do long hauls a lot then you could get 5k to 6k in between oil changes.But if you do a lot of stop and go and city driving you may want to do it at about 4k.&#39;ve heard that you can increase the interval between oil changes if you use a synthetic oil, but no one has been able to tell me precisely how much the interval can be expanded. I have a 2003 Pontiac Bonneville, 3.8l 6 cylinder engine, 128k miles.
