Here's the next UOA of my friend's 16 Mazda CX-5 2.5L Skyactiv engine. Both the oil and filter were replaced, filter is a Mazda 1WPE-14-302. The last oil test showed that the fuel dilution was over 5% and from everyone's input I thought it was most likely the short trip driving and the longer oil change interval. Since this is a direct injection engine, the shorter interval definitely lowered the fuel dilution! Was thinking of changing to Mobil 1 ESP 0w-30 but so far the currently being used M1 advance full synthetic (regular M1) looks good, but I welcome any opinions on this test result. I was a little concerned with the tin going up, but this is PPM, so maybe not a big deal?
