After break-in, at a direct pressure of 1,750 PSI, the torque for Popular Synthetic without additive increased to 32.0 lbs./in. and failed 1 minute and 3 seconds after break-in. At the same direct pressure, the torque for Popular Synthetic with the additive increased to 55.0 lbs./in.
However, it is important to note that this oil with the additive was able to continue and achieved the maximum direct pressure the test allows (4,500 PSI) in a period of 4 minutes and 28 seconds.
In analyzing the results, it appears that after 1,750 PSI direct pressure, the additive provided significantly more benefit.
It is interesting to note, that after the additive "kicked-in" the average increase in torque was .12 lbs./in per second. |
