I recently changed the oil and filter on my 2000 Buick Park Avenue with the supercharged 3800 V6 after about 3200 miles. I noticed the "oil life indicator" was only at about 50%. Since it has 150k miles on it I figured going with the old 3k-mile interval would be better but I did notice the oil was pretty clean and not much smell to it, also not super watery like would happen when I changed the oil in my 250k-mile Jeep 4.0L straight-6 (which I have a gut feeling runs the oil very hot, next one I get will have an oil cooler added).
I guess I'll try moving up to 4k oil change intervals on that car, it leaks/burns about a pint every 1500 miles or so anyway so I end up adding fresh oil before it's due for a change.
Here's some food for thought from guys who actually do regular maintenance and repairs on both gasoline and diesel engines, new and old... One of my favorite channels btw, Rich is a super cool guy I hope to meet him some time in real life.
