The owner’s manuals for my cars (1999 & 2003) advocate 5000 and 7000 mile intervals. Personally, I’ve been using synthetic oil (and high quality filters) and changing more like every 10,000 or once per year.
I believe the oil industry and Jiffy Lubes of the world are the main proponents of the 3000 mile interval.
You might want to get your oil analyzed. Doesn’t cost much, and it’ll tell you if you should be changing more often or not.
I agree-
All the lube places are pushing this nonsense.
The motors, the oil, and the fuel have come so far along that the 3K interval is BS. Even with a non-synthetic you’re fine past 3K. -IMHO
