Cadillac CTS-V Used Oil Analysis
Report
Engine Oil
C66 Racing team
owner Bradford Neff bought a 2006 Cadillac CTS-V as his daily driver in the
fall of 2006. The car was a used corporate car that had 7780 miles of use. In an attempt to
obtain information on the engine's performance over time, as well as how the
factory fluids compared to aftermarket alternatives such as AMSOIL, the team
drew used oil samples after each oil change and submit them to
Blackstone Laboratories for analysis from June 07 to Oct 09. The
car was sold in Sept 09 to a new owner who graciously took the last sample
and submitted it to Blackstone Labs.

Initial Fill
The engine oil and filter were changed by the dealer with GM Factory fill
for the CTS-V; Mobil 1 5w30 oil and an AC Delco PF-46 oil filter when the
car was purchased in October 2006.
Oil Change 6-10-07
After 2,856 miles of driving, almost entirely short daily commutes of less
than 10 miles, and with 25% showing on the GM Oil Life Monitor, the oil and
filter were changed and replaced with
AMSOIL Series
2000 0w30 and an AMSOIL EAO32
EA Oil Filter.
Oil Change
3-8-08
After 3,300 miles of driving, again almost entirely short daily commutes of less
than 10 miles, and with 25% showing on the GM Oil Life Monitor, the oil and
filter were changed and again replaced with
AMSOIL Series
2000 0w30 and an AMSOIL EAO32
EA Oil Filter. Although this oil change interval was about 10%
longer (by mileage) than the original interval for the Mobil 1, the Oil Life
Monitor reading was 25% for both of these intervals.
Oil Change 1-11-09
After 3,006 miles of driving, again almost entirely short daily commutes of less
than 10 miles, and with 25% showing on the GM Oil Life Monitor, the oil and
filter were changed and replaced with
AMSOIL Signature
Series 0w30 and an AMSOIL EAO32
EA Oil Filter.
Oil Change 10-18-09
After 3,209 miles of driving, and with 24% showing on the GM Oil Life Monitor, the oil and
filter were changed and replaced with
AMSOIL Signature
Series 0w30 and an AMSOIL EAO32
EA Oil Filter. Note: Due to a change of assignment from Washington
State to Washington DC with a new daily one way commute of 60 miles, the
CTS-V was sold to a new owner in Sept 09. The new owner put the last
600 miles on this interval and graciously submitted the sample from the oil
change to Blackstone Labs.
Our evaluation of the used oil
analysis reports:
- As evidenced by the SUS and cSt
viscosity results, the Mobil 1, AMSOIL Series 2000 0w30 and AMSOIL Signature
Series 0w30 all remained in grade for a 30 weight oil and did not
shear low out of grade or thicken
out of grade.
- As evidenced by the TBN of 6.1
for the AMSOIL Signature Series, 5.3
and 4.6 for the AMSOIL Series 2000 and 3.6 for the Mobil 1, all three oils had life remaining
and probably could have been taken down to 0% remaining on the GM Oil Life
Monitor.
- As evidenced by the ppm values
for the wear metals, primarily aluminum, iron, copper and lead, the engine
is exhibiting wear about 25-50% below the lab's universal averages for the AMSOIL.
