Growing up my dad insisted that oil is cheap, engines are not. He always changed at 2,000 miles when I was a kid, and his pickup to this day is spotless under the oil cap and valve covers - no varnish on anything inside. Before switching careers, I was an auto tech around the time manufacturers started switching to recommendations for 10k OCIs. I recall seeing vehicles come in with 50-60k on them with sludge buildup on everything metal inside the engine, including the dipstick.
I currently change all my vehicles between 4 - 5k due to short trips, cold weather, GDI turbo, and towing but I see a lot of people advocating 7,500 - 10k OCIs. With the availability of high quality oils and low prices these days, who else changes early and what's your reasoning?
