Just picked up 4 gals of penzoil 15w-40 it is ci-4plus rated. Any concerns? Just haven't heard much on this board about it.

The current version of Pennzoil Long Life is made by Shell and just happens to produce identical Virgin oil Analysis results as Shell Rotella. Most believe it is just rebadged Rotella. Before Pennzoil was bought by SOPUS, Pennzoil long life produced a unique looking VOA and indicated a fairly advanced additive pack. It doesn't look anything special any more.
