I respectfully disagree. Hes running shelf oil now and you know its got alot of metals in it from break in. No sense in keeping that junk in the sump to save $20.
That "junk" isn't in the sump. It's filtered out by the oil filter.
Exactly. Besides, the OP already did an oil change at 200 miles.
You guys know newer engines always show higher wear metals in uoas, sometimes even up to 50k they show slightly elevated wear metals.
The first 10k or so are generally the worst about wear metals throughout the life of the engine. Filters dont catch everything or else wear metals wouldn't be elevated in uoas of newer engines. Some wear metals like iron and such are abrasive, especially on soft metals like bearings.
Now this is just splitting hairs, I know, because if it was a serious issue the oem would specify shorter break in ocis. (But thats kinda what we do isnt it?)
So my point still stands. Why leave that junk in the sump to save $20? Theres absolutely nothing to gain when the FF was dumped at 200 miles, only thing to loose is suspended wear metals and the cost of the change.....and who knows it might extend the life of the engine from 300k to 320k.
