Dyson Analysis
2002 Camaro SS, 5.7L LS1 V-8
odometer = 1000 miles, factory oil (Mobil-1 Synthetic 5w30)
oil filter change at 600 miles to purolator pure-1 equivalent to AC-PF59,
1 qt of Mobil-1 synthetic 5w30 added to replace oil lost from filter change
Your results are below and look normal for a new engine and oil combo.
I will have to get the oxidation and nitration rerun as they came in as 0.
copper 201ppm elevated but normal reading for these engines on break-in.
look for 100 or less in the next 5000 miles.
Iron 23ppm normal, will drop to 10ppm range
Chrome 1ppm low
lead 6ppm normal until you romp on it, guys that race will see 20ppm
range unless they use a racing oil.
aluminum 5ppm normal
silicon 103ppm normal for new engine, will drop as RTV ends leaching process.
moly 63ppm elevated will drop unless you rev it on cold starts,
ring coating. See note below.
sodium 16ppm normal will drop to 10 ppm or less
magnesium 19ppm normal
tin 9ppm normal
zinc 677 normal additive
potassium 0 not in this oil
phosphorus 635 normal
Calcium 2130 higher than than the new "super syn" additive, either you
added oil or some additive to get this elevated. Not a problem
at all just sticks out to me. Usually show 1000ppm or less for new Mobil 1.
water,fuel,antifreeze all negative. scale neg,trace,pos
soot 38 not really relevant for a gas engine but we run it anyway. Use to
compare to later tests.
Oxidation, Nitration, Sulfur TBA... unable to be analyzed ==> very low
TBN 12 new oil, good
Vis @100C 10.6 mobil 1 30w, good
**Calcium and moly higher than I would expect, you didn't add the GM antiwear
stuff did you? If you added nothing then we'll expect to see moly drop in
later tests.
Overall consistent results,

Dyson analysis
2002 Camaro SS, 5.7L LS1 V-8
odometer = 4660 miles, 3685 miles on oil: Chevron 10w30 SL ($1.08/qt)
AC-PF58 oil filter, no oil added/lost
Dyson Analysis
Results ppm/% Comments (blank=normal)
Wear
Copper 151 normal for these engines
Iron 8 low
Chromium 1 low
Lead 9 normal
Aluminum 2 low
Silicon 27 coming into normal range
Tin 3 normal
Additives
Molybdenum 58 residual from M1,and wear in
Sodium 3
Magnesium 8
Zinc 916
Potassium 0
Phosphorus 767
Calcium 1790
Physical Properties
Water, Fuel, Antifreeze negative
Soot 0
Oxidation 11 low, good 6%
Nitration 52 low ,good 26.00%
Sulfur 0 low, low sulfur fuel and good ring seal
TBN 7 normal
Vis@100C 9.7 30w Starts at 10.5 cSt or so.
Final Comments : All wear values are excellent,
except for the GM copper levels. The Chevron is working well.
Expect Moly to drop to single digits as residual moly adds deplete.
Oil and engine combo good to 5000 mile intervals if desired.
Nitrogen bump up is colder weather in New England. Oxidation is low.
