A great many years ago, engine tolerances and oil performance improved and recommended oil change intervals for cars and light trucks were generally set at 7500 miles. Lots and lots of diehards kept with the old 3000 mile recommendations. Some still do. I used the 7500 mile recommendation. My Izuzu died when the A/T quit at 290K miles. I sold my CRV at 190K when I retired. The engine seemed to be perfect with almost no oil consumption.
Now my Ram uses synthetic oil and calls for changes at 15000 miles. I will follow that recommendation. Anyone who doubts the manufacturer's recommendations can have the oil tested or just change the oil much more frequently than needed. Your shop will be happy to do so.
