It all depends on if you use the "best" oil and change the oil at the "best" frequency.
Grandpa used to change his oil every 1000 miles (seriously). Of course he didn't really drive too much. He never had an engine problem.
I used to buy the "best" oil and used the "best" filters and changed the oil every 3000 miles. Also never had a problem.
I have an old car and I change the oil every 3 years. That amounts to about 500 miles. I realize I should at least do it annually, but after 15 years it hasn't had a problem either. The oil comes out still golden clear.
A "kid" at work got transferred a few years ago and was going to drive his car across the country. While gabbing at lunch one day he asked the "oldtimers" if we thought he should change his oil. We asked how long it was? He said "never". We asked how many miles. He said 80,000. The next day we helped him change it at lunch. It came out like tar. It took 2 changes to flush it out. When I saw him some years later I asked if his car was still running. Yup! Had 150,000 on her now. (He said he did change it a few more times though)
Personally, I think its much todo about nothing. If the oil meets the required specs, even if its wallyoil, I say it probably doesn't matter. Same for filters. Cars are built pretty well these days, and the use of synthetics have reduced the necessary time interval.
That's my story and I'm stickin' to it....LOL.
