[This review was collected as part of a promotion.] The product is exactly what my machine needed and the the 3 pack was convenient as it fit the quantity needed.

I have been using 15w-40 Shell Rotella in my two Chevrolet farm trucks, a 2018 5.3L and a 2020 6.6L as soon as the factory warranty expires. Both trucks start fine in -15 degree Wisconsin winters. The real value is in 90+ degree summers when hauling hay from the field and hauling a skid steer for loading and unloading the 1,000 lb bales. This oil is far superior to the 0w-20 OEM OIL. I change oil and filters every 3,000-5,000 miles. BTW, I also use it in my older farm tractors. Excellent Product

[This review was collected as part of a promotion.] Great Product with high quality standards to uphold.

[This review was collected as part of a promotion.] Use Shell Rotella for every oil change. Seems to last longer than other brands.

Needed 10W-30 API CK-4 for a new machine (It takes 17 GALLONS!) and this is the best price oil the meets the specs.

It is oil. Motor oil. It works and was delivered on time.

Good product, I use it frequently.
