First post. Blackstone report on factory fill 0W20, 2015 Mazda 3i Sport, Auto, 2.0L gas, US. Refilled with Castrol Magnatec 0W20. 5,017 miles on both the oil and the vehicle. Cold sample. Vehicle purchased late November 2015 with 55 miles on it. Think it was manufactured early 2015. Oil changed late March 2016. Decent mix of driving but mostly short trips in city.

Blackstone comments: "Your first sample from your new Mazda has a lot of metal and silicon in it, but don't worry - these results aren't problematic. The extra metal is from new parts wearing in and silicon is from harmless sealers used to put the engine together. It'll take a few oil changes to wash everything out, so we'll just watch for progress until things look more like universal averages, which show typical wear for this type of engine after 6,800 miles of oil use. The 2.3% fuel is cautionary, but some of it may be from cold sampling, idling, or even city driving. Check back for progress"
