Both the Trend and PPPC lifters operate well with high spring pressures and the DLC coating is a plus to prevent wear. DLC coatings have improved and most of the high end solid and roller lifters are DLC coated including, Jesel and Morel.

My Boss at my place of employment, was the engine shop manager for 30 years in several NASCAR teams. He used and we continue using both the Trend and PPPC, DLC coated lifters with no issues.

As regards to the engine oil and DLC coating compatibility, a few have experienced issues with the Driven oil. My recommendation would a synthetic oil such as Mobil 1, Lucas or Amsoil.

There are many SAE Engineering papers that have tested the compatibility and it appears that the recommendation for best wear is to use 5W-30 weight synthetic oil with DLC coated parts.
