Summary
1. These analyses used five tests in the on oil 820-2 plus seven tests from on low SAPS oils.
2. It is surprising to be able to find significant differences with so few reference tests and only one test on each of the other oils.
3. The charts show each test result plus the mean for 820-2 and upper and lower limits for determining whether individual test results on the low SAPS oils are significantly (p=0.05) different from 820-2.
4. Outlier screening was done with no profiles and not for all tests. Pb was corrected for the UBWL outlier using the T-10 method.
5. Significant differences were seen for • Delta Pb 0 to 300 corrected for UBWL outlier;• Delta Pb 0 to 300 Lab G Test Removed• Top Ring Weight Loss (Lab A Near Outlier Removed)• Oil Consumption; and • Delta Pb 250 to 300.
