Best oil for my Dodge Cummins Diesel

I am very particular about my vehicles. My research determined that this is the best oil to use for my Cummins Diesel. I was surprised when my research showed that Walmart carried this oil and they also had the best price.

[This review was collected as part of a promotion.] Inflation is hitting everything. But Walmart does a good job at offering good prices on name brand items

[This review was collected as part of a promotion.] Using product for many years-exceeds specs of oil used by Ford dealers when doing oil changes. Consistently rated in top 1 or 2 reasonably priced oils for diesel engines.
