The only reason to use full synthetic oil is to extend oil change intervals by having samples analyzed at regular intervals. The cost of synthetic oil doesn't make sense to run it and drain it at normal intervals. The only advantage of synthetic over regular oil is less dirt retention and a wider temperature profile. If you drain at normal schedule or don;t have an excessive temperature problem, no need for high price oil. Its a waste of money.
I guess it depends on how much oil your rig holds. On my daily driver, which I put about 30k a year on, my additional cost of running Mobil 1 is about $40 per year over using conventional oil. This is sticking to the manufacturers recommended intervals. To me, $40 isn't worth the effort of having the oil analyzed. Of course this would be a moot point depending on the oil capacity of a particular rig!
