Tsoa, He had 3200 miles on it before he changed the oil!!!! If it was not broken in by then it is never going to break in!!! How long do you think it takes to seat rings???? How long do think it takes for cam followers to wear in enough for break in to be done with????
Honda's OEM oil has an insane amount of molly in it compared to anything you can buy over the counter!! THe only oil with more moly then Honda break in oil is Redline. If memory serves me right Honda factory fill has something like 359ppm of molly in the oil and this was after something like 5000 miles in the crankcase so we know some of it was taken up by the engine!
The top ring is tapered and chromemoly plated. Their are simply not that many asperitys! The valve train componets are broken in in the first 20 minutes of runnings so all that is left is rings,timeing chains and oil pump. Guides and bearings simply wear out.
Their are quite a few people in the Automotive field that claim that you get the first 12-20 miles to get a good ring to cylinder wear pattern and that after that you are out of luck. I do not know that I subcribe to this belife but is surely does not require 15,000 mile, 10,000, or even 5000 miles. Now I want to be clear that I am not talking about trending down of wear metals. I am talking about the rings sealing properly and the acclerated wear particles ending. When an engine is breaking in you will see alot huge wear particles.By huge I am talking well over 20 microns like 40 microns and larger. Once breakin is finished the wear numbers may well be high for a while yet to come but the average size of the particles come to 20 microns and smaller. You would have to send in the oil filter and have them count the number of particles by size to really see this.
If their was any truth to synthetic oil causeing problems with breakin your most expensive Luxury and High Performance vechiles would not use synthetics as factory fill! We have all seen how well some non-synthetics do at preventing wear on this site. Heck Schaffers turns in better numbers then M1 in a lot of cases. Chevron Supreme has about the same additive package as M1 and has in some cases bested M1 as well.
I put synthetic in quite a few motors either at the 500 mile mark or after the 20 minute run in and never had a problem. Who here on this site has had an engine fail to breakin over the life of the engine because they ran synthetic in it after 3200 miles????
