6.7 turbo stroke. Analyzed after 5,000 miles. Plenty of add pack remains. Can run longer but I don’t.

So far so good! lol. First oil change on F-250. Meet API CJ4 standards. No ticking after I changed @ 4k miles.

best deal on quality diesel oil. 5W40 is good for winter. sure Amsoil is better but their price is ridiculous. this one is the best value and has been tested to prove that.

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!

This oil is approved for the 2014-up Ram and Jeep Ecodiesel engines which used to require Penzoil Euro at $9-$10/quart. This meets mfg. requirements for low ash and proper lubrication for around half the price.

Great quality, awesome service and well worth of your money. I compared the prices of shell rotella engine oil and found it at best price at Walmart. I have purchased this item from Walmart before and purchased it again few weeks ago.

I use this brand in all my diesels truck as well as my heavy equipment .

Run it in all the mowers and atv's...

Have used for 200,000 miles on my ram w zero issues

Great for 2.8l LWN Duramax diesel. Oil analysis shows excellent results.
