Common sense my friend!!
If you took two identical trucks with equal engine wear ( lets say 240,000 on the odometer ) and both trucks were know to ( USE OIL ) between oil changes and maybe had a minor leak around some gasket and you emptied the oil in each truck and in one truck you put in ( FULL SYNTHETIC ) and the other truck you put in ( HIGH MILEAGE OIL/NON SYNTHETIC ) and ran each truck for 5.000 miles I " guarantee " the truck that uses ( NON SYNTHETIC ) would show MORE oil on the dip stick!!!!!!! PERIOD
Everyone here needs more that "Its common sense my friend" what does that prove?
Did you know that synth will break down less over time? So if you use a non-synth, your oil will break down faster, limiting its lubrication qualities. I am not saying run your oil for 10,000 miles, cause the filter generally isn't good for more that 6-7000, but think about it.
Scientific proof from a 3rd party analyst??
Couldn't have said it better.
I will believe science over some guy on the interwebz any day, sorry
