[This review was collected as part of a promotion.] Recently began using this product for my vehicle since it significantly improves the engine. The discount Walmart provided was exceptionally amazing since it is pricey.

in different applications, both petrol and diesel, this oil provides turbocharged engines with sufficient protection. has that trademark shell smell, but that's alright.

Been using this oil in my 2016 Ram Ecodiesel for over 90k miles and no problems, my oil sample reports come back showing no issues or concerns with the oil.

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.

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.

Tried this oil versus Valvoline Blue 10W30 and Valvoline is better. Valvoline oil offered better MPGs and did not produce such a strong oil odor from tail pipe emissions. Valvoline Blue is still superior over Rotella.

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.

The oil is top notch. What really impressed me was the extent Walmart employees went to in protecting the containers of oil from leakage and damage when shipping! Awesome job!

This high-quality full-synthetic motor oil works great in my Can-Am Spyder RTL. I recommend it to anyone needing this oil grade for their motorcycle, car, or truck.

I made my 2nd order of this Rotella T6 online, and very pleased with Walmart service. Everything got delivered clean and sealed, with no issues. Great product and great service!
