First time oil analysis on a 2016 Mazda 3 Sport 2.0 liter NA. Mostly short hop city driving. Purchased new in 2016. Only Mazda oil filters have been used. 1WPE-14-302. Initially the Mazda 0w20 high moly oil was used up to 25,000 miles. After that Quaker State 0w20 up to 35,000 and then the Valvoline Advanced 0w20. Decided to run the sample because I was concerned about the small amount of coolant loss and fuel dilution. Fuel dilution is at a high level at 2,068 miles and it appears no coolant intrusion. Prior oil changes were done around 4,000. If I would have known about the high fuel dilution, I would have changed it much sooner.
