Amsoil has addressed the entire problem with engine wear rather than just half of it.  Half of the problem is preventing the parts from touching each other and the other half is keeping the contaminates out of the engine through the use of high quality air and oil filters.  If you address these two problems, then your engine will last indefinetly.  Synthetic oils do not break down like the petroleum oils do therefore, if you keep the contaminates out then you can extend the oil change interval indefinetly.  The use of Amsoil products makes it possible for a gasoline engine to go 25,000 miles on an oil change and 100,000 mile oil change interval with the use of Amsoil's Bypass filter.  Amsoil is the only company that warrants this length of oil change interval.  In fact Amsoil has been offering this for over 35 years.  Most of the competitors do not reccomend a length of oil change interval because they do not have the benefit of the Amsoil oil filtration.  The benefit of Amsoil selling their own oil filters is that they do not manufacture them to price but to quality.  Other synthetic oil manufacturers have to rely on the quality of the oil filter manufacturers that design filters for petroleum oils that can only offer a 3,000 mile oil change interval.  The cost of an Amsoil oil change is the same as three trips to the quick lube but lasts eight times as long.
