I do know that synthetic oils have a lot smaller molecular structure than conventional motor oils. Oil control rings and combustion rings will get more blow by (exhaust gasses) passed by them and if this is the case all you would be doing is getting your oil contaminated think about it most manufactures do not want it used in there engines. Do not get me wrong it is great for thermal break downs. But most oils do not break down. Their additives burn off. That is why I change oil more often and use a factory recommended oil filter. Some oil filters have better flow and some have the ability to not let the engine oil drain back (check valve) they keep the oil gallies full when shut off for a long period of time and if you use a filter or synthetic oil that can have an effect on things you will wear parts prematurely, valve stems will cook oil faster and bring it back to the structure of the base that the oil was started with. you will have dirty oil due to the detergents in the oil (this is normal) and the oil filter should do just that, filter the oil but what do you want to filter the dirty oil or do you want to filter fine metals let the oil suspend the dirt as it should and carry fine particulats to the filter. This can go on and on. Tony
