Cummins/Valvoline Premium Blue CJ Oil
Analysis Results

Just an hour or so after we posted the article, CI-4 Plus Lube Oil Availability Problem?, we received the results for the CJ version of the Cummins/Valvoline Premium Blue CJ Oil.

The oil analysis for the CJ version of the Premium Blue product is posted as entry 22 on our Oil Analysis Chart.  (Click here to download updated .pdf version of Oil Analysis Chart).  Since the CI-4 plus Premium Blue was our entry 1 oil, it is easy to compare the two products.

If you compare it to the other CJ oils in our test, it is similar to the other CJ oils with its lack of TBN, calcium, phosphorus and zinc.

We don't think I need to call John Martin. Put this oil into the CJ bin known as "Ho-Hum/least favorite."
