I have used Power Service I bought from Walmart for my Perkins 100. This is currently cheaper, but I will pass because I don't know of any clear benefit. A recent video from the Motor Oil Geek tells that this product is decent, but I am not sure how it compares with Power Service for cetane and anti-gel properties.

Actual testing shows this is not really worth it at all. Repair Geek did a review on youtube and other tests I've seen shows it doesnt help with lubricity, only adds a small amount of cetane, less than other brands tested. Cetane is not really important, people with CP3 or CP4 pumps need lubricity!

Just use a few oz of ash-free two stroke oil. I've been using this on my 11 Ram cummins for 4 years and zero issues. Also makes the engine much quieter.
