I use this synthetic oil in my motorcycle because it has the certifications for wet clutch application. Way better price than HD, Castrol, or BMW branded oil.

This oil was recently added to the approved list for RAM Ecodiesel. It is half the price of their previously approved oils. Order it for pickup on Walmart.com to save an additional $3 on 3 gallons. Shell and Walmart, thanks for taking care of us!

price is high considering it is only 4 quarts. Most Mobil1 is 5. Walmart has the best price I've found. I run this T6 5W40 in all my diesels. Kubota L3020, International DT466e and T444e.

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.

The only issue we found with this was that it only comes in one size at the store. We needed one extra quart and had to get another whole one this size.

this is the oil recommended for my vehicle by GMC. very difficult to find locally but was able to order through Walmart and received it NEXT DAY, with free shipping.

I like the fact that Walmart stocks Rotella T6 5w40. I really like the performance of this full synthetic oil for my Ford F350. I would like to see better cost savings if possible but overall satisfied by offering.

[This review was collected as part of a promotion.] This is the only product that I use for my truck., and having it available and at a reasonable price is a big plus.

I use this in my 2001 Ford F-350 7.3 diesel and I think it runs better with this oil then 15w-40. Also when it's cold it starts much better. Great oil and a great price

Great full synthetic oil for a reasonable price. I use it in my motocross dirt bike, my ram 2500 diesel, and my any small engines I have around the shop. It meets JASO-MA2 specifications for motorcycle wet clutch use.
