Cowboy, did I even post anything about “engine failed prematurely”. I just stated, yet again, </font><font color="blue" class="small">( ( Example here since you might need one. If you follow the manual (for example again) on my
BX22 you can go 1 year on dino oil and every OTHER year on oil filters. And how many do that????) ). )</font>
I also have not read or found anyone that had “engine failed prematurely” by doing extended drains (using a real synthetic) if following the oil manufactures instructions (much sooner). It can go both ways my friend.
So to close, doing drains at 3,000 are proven to do nothing or doing drains before what is “recommended” does nothing unless you use a very cheap oil. That is a fact if you some homework. I can't post all the data since I can't hold everyone’s hand all the time.
Most people to not even do what is recommended in the manual. So as what I have stated long before, doing/going longer then what is outlined in the manual will do nothing if you use a real synthetic oil (group 4 and 5. Not a 3). Also I am one of the select few that has even posted an oil test #’s.

You can show me papers still you are blue in the face, but I will take raw data (oil tests) over these paper any day! Since these are real Empirical (observation or experience) data
