Lubricants Group Ballot
Volvo T-13 Group II to Group II Base Oil Interchange
Ballot to Establish Volvo T-13 Base Oil Interchange (BOI) for API Group II to API Group II
Lubricants Group Members reviewed the recommendation on Volvo T-13 Group II to Group II BOI from
the BOI/VGRA Task Force. The data analysis from the PC-11 Volvo T-13 Precision and BOI Test
Matrix is attached to this Ballot as Appendix I. After reviewing the Volvo T-13 data the Lubricants Group
agreed to ballot Volvo T-13 BOI with Group II to Group II BOI.
A draft of the Volvo T-13 BOI Table is given below with the Group II to Group II read across highlighted.
E.3.2.5.xxx If only one passing VolvoT-13 test is available on a given technology, Table E-xx applies.

Mack T13 Precision / BOI Matrix Data
for BOI / VGRA Task Force
Jim Rutherford
03/03/2015
Outcome
 For both
• Precision analysis for IR Oxidation Peak Height at EOT, and
• Precision analysis for 40° percent viscosity increase from 300
to 360 hours
 Technology was significant.
• Technology 2 was significantly different from the other two
technologies.
• The other two technologies were not significantly different
from each other.
 Base oil was not significant.

Available Data
The LTMS dataset had 34 tests. Two were XC (aborted) and rerun
from the designed matrix. Three were matrix oils run in nonmatrix stands. There was one repeat with modified filter head.
The task force decided to delete three tests (testkeys 103550,
105822, and 104623) from the precision analysis based on
operational anomalies leaving 29 tests for analyses.

Precision analysis for IR Oxidation
Peak Height at EOT
o The full model contains effects of technology, base oil,
interaction between technology and base oil, laboratory, and
stand within laboratory.
o The only significant effect in the full model was technology.
o The minimum RMSE model that contained technology, base oil
and their interaction so that oil targets could be estimated also
included laboratory which was marginally significant.
o Although one test was flagged as a potential low outlier (testkey
103587), there was no reason found for deleting it.
