Infineum increased the phosphorus level from 0.05% to 0.19% in the test oil. ZDDP has an exponential decrease in LSPI activity - higher levels of ZDDP reduced over 90% of LSPI events compared to the number that occurred with the 0.05% ZDDP oil, confirming ZDDP as an LSPI quencher.

Effect of increased concentration of ZDDP in Baseline Oil 1 on LSPI
Further evaluation of ZDDP, looking at different alkyl length groups at fixed phosphorus levels, did not reveal statistically significant effects, confirming ZDDP to be a quencher regardless of chemistry.
These observations open up the debate for increasing the phosphorus maximum levels in the next generation of Industry and OEM lubricant specifications.
