I buy my oil from a local distributor, this hasn't been an issue yet. But today I pumped 5 gallons of 15w40 fleet supreme into my series 60 and found particles at the bottom of the bucket. I called my rep right away, he said it happens on buckets that have been sitting and it's ok, but I expressed these are hard, like oil dri or small pieces of gravel, he then said that's not good and that's not normal, something about the additive package can break down and create deposits, but definitely not hard like these.
So, the engine hasn't been run, our thoughts are, remove the filters for new ones since they're prefilled, drain out what's in there, refill with 4-5 gallons of something to flush the sump.
The filters should catch any of these big particles before the engine sees them, however, my last oil sample came back with high silicon levels, nothing was changed prior to that sample and the engine is brand new, is it possible the oil is dirty out of the bucket?
