It’s the starting and stop in that will get you. Years ago My Aunt use to change her oil every 3000 miles. She only made short trips rarely engine got the engine GOOD and warm. The problem was it would take 2 or 3 years or more to come close to 3000 miles. Her 8 year old car with less than 25K miles sounded like non oiled sowing machine. You could hear every lifter smacking the the valve stems.
even more important today with fuel ejection, high pressure fuel deliveries, and especially turbo charged. With stop and go driving excess heat it breaks down the oil faster, oil eventually becomes black and gooey. This coked up small passages VVT, piston compression rings, create more heat in turbo charger faster. Only way to reduce this problem is with oil changes. It usually takes 80K plus to gum up engine with minimal maintenance. Most people don’t keep vehicles that long. I would never leave oil in my vehicles over 2 years regardless of miles.
