here are results of my brothers car I ended up with after my 1991 SHO was stolen
from me last sept.
We bought the car in 2004 and added AMSOIL into the engine and from all the upkeep
after buying a used car we just never felt like changing the oil, it used/leaked
a quart every 1000 miles,
just a few months ago the car quit running and I had to change all the sensors
and I fixed the leaking cam sensor seal that was stealing all my money. so now
the oil stays put, I am posting up the results from it's first UOA and I wonder
if I need to change the oil? from the results I dont think I need to.
One thing I may need to change with this particular engine is the Rod bearings
, since these engines are known for beating them up.
well here we go
Aluminum 3
Chromium 2
Iron 20
Copper 7
Lead 36
Tin 3
Moly 48
Potassium 2
Silicon 7
Sodium 9
Calcium 3077
Magnesium 15
Phosphorus 672
boron n/a
Zinc 828
cST Viscosity @100 10.9
no tbn with this sample
with more than 30,000 miles on this oil and plenty of fresh
quarts added in over the years this oil will stay in the crankcase
