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.
Normal oil change: I use the best synthetic oil I can lay my hands on and dump it every 4000kms (2500 miles) religiously. After many, many hours scouring the net for info I believe the best synthetic oil for your Harley is either Amsoil or Mobil 1.
