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.

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.

Have used this item exclusively for over 20 years on my Diesel engines Have over a million miles on several trucks Delvac is the best for long engine life

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.

[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.

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

[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.

[This review was collected as part of a promotion.] Tried and true product. I usually purchase in bulk. However the oil price is too high to purchase bulk quantities.

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.

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.
