[This review was collected as part of a promotion.] I actually needed the 15-40, it is for sore a great product. I use it in my ram 2500 regularly.

[This review was collected as part of a promotion.] This oil is the best for my diesel truck. Factory recommended and a decent price.

This oil works hard to protect my 24-year-old 7.3 liter Ford diesel. Almost 350,000 miles and still going strong.

Bought my 2011 Ram 6 7 Cummins and went right to the service department and had them change the oil to this. Been using it ever since

Made my Cummins run much smoother, don’t know what the previous owner had in it but it wasn’t t6. Will be buying more for all future oil changes

If your looking for the best all around oil, this is it. What are you waiting for, just buy it, you wont be sorry.

Shell Rotella T6 synthetic oil 5W 40 is nearly impossible to find in the store. Online is the way to purchase this item!

This oil is generally hard to find and, at times very expensive. Seems its always in stock when i need it at a great price.

Love this stuff. Won’t use anything else in my truck. 62,000 miles so far and this is all I’ve ever used.

If you run a diesel the only way to go is Rotrella-15/40 T6 The very best in oil.You will not be sorry!
