I am not going to getting into an argument with anyone but fact of the matter is there is zero evidence that changing you oil more often than the OLM indicates is a waste of money. The OLM uses a complex algorithm that takes into consideration miles, temperatures, trip length, speeds, rpm's, acceleration, idling time etc etc. When was the last time your heard of someone needing a valve job or an engine with a bad rod or a shot cam shaft? No you don't hear of it and its because of the engine design, over head cams, fuel injection and engines running at such low RPM's due to high torque and six speeds transmission. Finally, I posted this previously;
Consumers Report did a long term study of NYC Taxi cabs with half using 3000 mile OCI and the other half the manufacturers recommend interval. After 100,000 of thousand of miles of driving they tore the engines down and in fact found no difference in engine wear, sludge, oil consumption etc. Search Consumer Reports Taxi cab oil test and you can find the info. This was probably five years ago but it would still be applicable. For the main study they used conventional oils but they did run Mobil 1 in a couple of taxi's and in fact one of them suffered an engine failure. I think they said they determined the failure was not related to lubrication.
The shade tree mechanic that claims 3000 or 5000 miles is the "right" interval has only anecdotal data, nothing concrete to back it up.
