Even though prices are steadily on the rise ,Walmart has some of the great low prices , automotive , diesel trucks ect ,I will go there first before I go to the corner part store because more than likely Walmart or Walmart. Com will have it.

I really like purchasing the oil and doing the oil change on my 2500 Heavy Duty truck. I can do this myself and save over $100.00 on having a Dealership change it.

Switched to this from Rotella T-5 truck runs just as good with this oil. I change the oil in my duramax every 5k miles which could get costly, this oil keeps operating costs down and makes changing more frequent easy on the wallet. A+

[This review was collected as part of a promotion.] Used the product for many years with good results. Walmart has the best price and availability of any merchandizer.

Mobile Devac 1300 15w-40 1 Gal is awesome oil for many diesel motor application. Run this is larger Mack trucks to International Semi trucks. Also in F350. Used for decades.

Non synthetic oil is getting harder to find as newer diesel engines require synthetic oil. As an older diesel truck owner, a synthetic blend oil is the next best thing.

put this in my 6.4 powerstroke and change every 8k seems to be working great for me so far. I have used this 3 times already I don't know how they can sell it so cheap but I like this product best for the price if you ask me

Love the product but the delivery was horrible! Items were left in clear view of the street to where someone could have easily come and stolen my order. I didnt receive notification that my order was delivered until several hours had passed.

It's oil for an engine, what else is there to review. it performs as expected. gets dirty as expected, must be changed at interval as expected. If engine had grenaded, that would have not been as expected.
