Why I'm switching BACK to Honda oil

[kDiqq_imp]

I tried to have a dealer diagnose the bottom end rattle, but they said everything seemed fine... Using a stethoscope and parts diagram, I did isolate the noise to be coming from WELL below the balance shaft and crankshaft. In fact, it's even below the oil pump itself and it coming from where the return tube reaches the pan. Since there is no gasket for the oil pan, I deemed it not worth pulling the pan myself and reapplying gasket maker. Dealer said it's fine and I have that documented, so if problems arise later it should be easier to file a claim since the condition was report at <200 miles with factory oil.

I'm puzzled on why the pan has loads of baffling for the oil return...
