- Comparative Example 1 (containing mineral derived Group I base oils) did not pass the tensile strength part of the AK6 test (-52.3%; beyond the limit of -50% min), whilst Examples 1 and 2 (containing a combination of Fischer-Tropsch derived base oil and mineral Group I base oil) did pass.
- the tensile strength gives a good impression of the extent to which the mechanical properties of a test specimen change upon contact with lubricant; a large % means better results.
- Examples 1 and 2 exceeded Comparative Example 1 significantly in the NBR34 test with respect to volume change (2.0 and 2.5 versus 3.4) and tensile strength (2.8 and 0.4 versus -3.6); in the ACM E7503 test with respect to volume change (1.5 and 2.5 versus 3.4) and tensile strength (3.5 and 2.8 versus - 1.4); and in the EAM D8948-200 test with respect to hardness (2 and 0 versus -3) and volume change (2.9 and 6.1 versus 10.3). Seal swell or shrinkage can have an effect on the sealing performance; a minimal change in volume upon contact with lubricant is desired to ensure the seal gives the fit for which it is designed.
- Examples 3 and 4 exceeded Comparative Example 2 (containing mineral derived Group II base oil) significantly in the ACM E7503 test with respect to volume change (1.7 and 1.8 versus 2.4) and in the EAM D8948-200 test with respect to hardness (5 and 4 versus 2) and volume change (0.8 and 1.8 versus 4.8).
- the lubricating compositions according to the present invention also exhibited good dispersancy properties.
- Table 3 and Figure 1 show that Example 1 and 2 perform better than Comp. Ex. 1, whilst there is a preference for Example 1 in respect of dispersancy properties.
- the lubricating compositions according to the present invention further exhibited improved low T pumpability properties (as evidenced by high reduction rates).
