Hi,
This is my first UOA for my 2014 Mazda 3 GT from the first oil change.
USE: Daily driver, pretty much all short city trips except for about 1500km of highway for a few road trips. I have a really short (~7km drive to work) and when it's cold I do let the engine warm up for a minute while I'm brushing snow or whatever. Sample was taken by the dealer (about 15 minutes drive away) and stored at home for about 2 weeks until the kit from blackstone arrived in the mail.
COMMENTS:
You were right about the moly. A reading of 572 ppm is a lot of molybdenum additive compared to most oils. It's a harmless antiwear additive, but we don't really see a benefit from having more or less in use. The high metals and silicon in this sample are just residual from wear-in, and everything should start to resemble universal averages (based on about 10,700 km) after a few more oil changes. The TBN was 3.8. Running 11,000 kilometers would be fine next time. The viscosity at 40º C was 28.87 cSt.
LAB: Blackstone
Code:
MI on Oil 8,145
MI on Unit 8,145
Sample Date 12/30/14
Make Up Oil Added 0 quarts
Oil Type & Grade Factory Fill possibly Mazda 0W20 with Moly (MGMO)
Universal Avgs
ALUMINUM 8 4
CHROMIUM 1 0
IRON 28 11
COPPER 36 6
LEAD 0 0
TIN 1 1
MOLYBDENUM 572 164
NICKEL 0 0
MANGANESE 1 0
SILVER 0 0
TITANIUM 0 0
POTASSIUM 8 1
BORON 176 73
SILICON 64 15
SODIUM 9 4
CALCIUM 1980 1508
MAGNESIUM 10 543
PHOSPHORUS 636 645
ZINC 716 748
BARIUM 12 1
Values Should Be
SUS Viscosity @ 210°F 47.8 46-57
cSt Viscosity @ 100°C 6.60 6.0-9.7
Flashpoint in °F 355 >385
Fuel %
Antifreeze % 0.0 0.0
Water % 0.0
Insolubles 0.2
TBN 3.8 >1.0
I'm new to this whole oil analysis but it looks like the Flashpoint is a bit low and possibly the cSt Viscosity @ 100°C.

Any comments, thoughts, advice would be appreciated. Oh and let me know if I forget any required info? Thanks.
