Quote:Thank you all for your excellent comments. I did think the article was interesting, but it would have been nice to see some actual data. The authors did mention, "Testing with partially stressed oil, which contained some wear debris, produced less wear than testing with clean oil." However, unless I'm missing something, this testing was over extremely short intervals when compared to 1000s of miles. The results could, but do not necessarily speak to wear rates at 8K versus 13K miles. I currently have the same oil in, so it will be interesting to see the results at half the interval.
Here's some testing done on this subject. http://www.swri.org/3pubs/IRD1999/03912699.htm
