Guys, have you ever heard of statistical versus practical significance? Even if there was a statistical difference between those values, you'd never be able to show that changing your oil

Guys, have you ever heard of statistical versus practical significance? Even if there was a statistical difference between those values, you'd never be able to show that changing your oil based on those numbers was worth doing every 1000 miles. Don't waste your hard earned money every 1000 miles...there's no evidence that a little extra copper, iron, molybdenum, etc will change your engine's life.

I feel that changing your oil at the FIRST 1K miles should be done. Not waiting 4500 for the very first oil change. For the normal driver, after the first 1K, I don't see why waiting 3-4K every change AFTER the first will be fine. My point was simply that doing the very first one should be done sooner than later.

I grew up learning that (and I'm REALLY old). The idea wasn't so much that the oil was breaking down or anything but that in the first (let's say) 500 - 1,000 miles is where you will gather the most fine particles of metal "dust", (etc.) as the engine breaks in and the metals smooth themselves into place. Dumping that oil gets rid of foreign minute particles floating around in it.
