Here are results from Dyson Analysis. Car is a 2000 VW Jetta 1.8T, GIAC performance chip (runs about twice the stock boost pressure), full 3" exhaust, and an aftermarket cold air intake with a K&N-type cone filter inside the bumper. A few other mods not worth mentioning. Spark plugs are Autolite 3924 gapped appropriately. 4145 miles on oil, 45K miles on car. Mostly highway miles at 70-80mph in hot, humid weather, with A/C on. Plenty of WOT, full boost use, but not as much overall load as driving in town.

Results (ppm unless noted) comments
WEAR METALS
copper 3 low, normal
iron 11 normal
chrome 0 low
lead 2 low
aluminum 2 low
silicon 11 normal
moly 1 low
sodium 4 low
magnesium 1320 elevated, monitor,can be a
additive . very unusual for this engine and oil combo.
tin 0 very low
ADDITIVES
Zinc 672 normal
potassium 8 normal
phosphorus 594 normal
calcium 762 normal
CONDITIONS
water neg normal
fuel neg normal
glycol neg normal
soot 40 scale 0-199 ,not
completely relevant for diesels, but use for comparison with other tests.
Oxidation 22 scale same as
above, divide by 2 for comparable value to other lab results =11
excellent result.
Nitration 16 scale and
relative value same as above. very low ,means very good combustion
efficiency.
sulfur 20 scale the same,
primarily for diesels. compare to later results.
TBN 10 Acid neutralization
capability, starts at 11 to 13, normal.
Viscosity @ 100 C 11.4 cSt Begins at 10cSt so it has
thickened slightly, still 30w.
Summary Engine and oil are fine after 4145 miles. Wear values are very
low. The engine is burning very efficiently. MG is the only ? mark for me.
I'll check with the lab to ensure it is not a typo. Ask any questions or if
any clarification is needed .
******************
Analysis says the M1 SJ formula does pretty well, but it did thicken up a little. My aftermarket intake is doing a good job filtering based on the silicon numbers, and the el cheapo spark plugs are doing great as expected (single electrode copper plugs...they don't last long, but they sure do make a good burn).
Only question mark is the Magnesium. I'm wondering if something in my engine/turbo contains magesium and is wearing?
Supersyn results will be out probably in early September. Usage of the vehicle and other factors will be similar, so should make a good comparison.
