I've been using this Rotella in my caterpillar engine, it has outstanding some other products and help me with cost, since I don't have to change oil as often.

I buy the 5w-40 at the store, is fantastic oil. I run it in my 1999 Toyota Tacoma, Polaris Ranger and John Deere tractor. All 3 engines run quieter, cool and clean. Amazing oil. I may start running it in my lawnmower and generator as well.

Used in my Ram Eco diesel pickup, excellent oil meets all the manufactures specs. Wal*Mart's exceptional price prompted me to buy extra for next oil change.

I live in a cold climate at or above 15 degrees, I just did a oil change on my 05 F350 6.0L powerstroke 90KM, works good but takes 30 mins for oil to heat up with engine heater

I’ve legit been using this oil in my trucks since 2013 and haven’t touched anything else since. This oil has saved me much money and kept my trucks from being placed out of service due to engine and turbo issues.

Wonderful Oil. I use it in my 2005 Subaru STI. I change the oil every 3700k miles. The techs at the shop always my oil still looks like its in great shape!

In my motorcycle - 2015 BMWR1200GSA - for over 80,000miles In my 2001 Nissan Pahfinder with VQ35 engine. In my Honda scooter (not that the scooter cares what oil it gets) 6.0 Powestroke diesels love this stuff. (I used to be a diesel mechanic)

When your running a 7.3 powerstroke good oil is a must. This oil has my truck purring line a kitten. Much easier engine starts even in the heart of winter.

I have been using this oil since I bought my Ram diesel. I work great with the 5 40 it will protect even in near zero weather, and covers the high end also with the 40 weight end. Great oil for any diesel engine out there.

Arrived on time and In good shape. Great oil for a good price. Much cheaper than the Advanced Auto 25 miles away. Delivered to my door and I didn’t have to drive 50 miles........I’m happy.
