I've always wondered why the oil change interval is still 3K miles...........and it's been that since I can remember back to the '60's. It's not like oil hasn't improved since then....and it has, significantly......or oil filters haven't gotten better-----they have, significantly------and yet we keep getting told we must change our oil every 3K miles.
So, let's recap......much cleaner burning engines and engines built with much better metals and manufacturing techniques, significantly better oil over the past 4 decades, significantly better oil filtering media in the last 4 decades, still we haven't been able to lengthen the oil change interval. Odd and strange.......
