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.

[This review was collected as part of a promotion.] Been using mobile delvac for my semi-truck and **** trailer for years now for my motor home as far as i am concerned the best oil on the market

[This review was collected as part of a promotion.] I love the fact that I don't have to go to the store to pick this item up. It was already packaged as 4 per box, and it was also on sale. It makes my life much easier.

[This review was collected as part of a promotion.] I like delvac 15/40 oil for my diesel motor home and my duramax Chevy truck, Same price as Lowe’s so I ordered it, did not have to pick it up.

I much rather have bought the two 5 gallon bundle for half the price but since your app has incorrect availability I was very disappointed to be forced to settle with this more expensive option

i got a case 580 sm and if you know diesel tractors their oil can become sooted and darker that a night sky with no stars or moon. i like to keep it changed and this foots the bill.

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.

I wonder why they call this synthetic oil when they have another labeled bottle marked full synthetic and it cost more, this bottle does not show it being synthetic oil, I still use it but would like to know the answer to this.

[This review was collected as part of a promotion.] The reason is because the product came in excellent condition and price was the best on the online marketplace.

I live off grid in Florida so I need a heavy oil to run my generator during the heat of the day.Mobile Delvac 15/40 has proven to best the best and the price is right.
