    Good diesel oil I guess how would I know
    I have used Mobil and Chevron and Texaco brands my entire life and at the time of purchase Mobil was the cheapest Walmart had, even cheaper than the store brand, so I bought it. A few bucks less makes a bigger difference when you have to buy 4 gallons for every oil change.

    Works well in my Ford SuperDuty
    I have used Mobil products exclusively in my Ford Superduty. Lubrication is the cheapest way to protect your investment. They are the only name for my vehicles.

    Delvac - Keeps my Model A running smooth!
    I have been using Delvac in my 1930 Model A Coupe since I got it 8 years ago. I change my oil every 1500 miles and it is always clean and amber. The additives and weight are perfect for my old car.

    Works for me.
    I have been using Delvac 15-40 in my 2004 Dodge CRD since day one. Currently at 150K miles. The oil is dumped every 5K miles and always use Cummins filters. A recent oil analysis by Blackstone revealed excellent results with a quote "this Cummins CRD appears to be in excellent condition". That is a good enough reason for me to continue using this oil.

    Clean engine
    I have been using Delvac oil for years in my antique car. Took off the oil pan after 90000 miles and the engine was as clean as when I installed it. Thank you Delvac

    The best there is.
    I have been using this oil for years in my trucks and my farm tractors. I had to put new injectors in my 2001 truck and the inside looked brand new. No oil build up. CLEAN! You won't go wrong with this oil. Mobil Delvac 15W-40

    Go to Walmart or Walmart. Com first -A 1 !!!
    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.

    Good value.
    Good oil at a good price. Listing claims synthetic blend , but I don't think it is.

    Hello, I asked for 12 gallons of oil but they only brought me 11 and I would like all the gallons to appear in the photo they take because if they take it in the car they cannot be counted and there is no proof that they sent me the amount I asked for.

    I ordered 4 items by online. They said its ready to pick Walmart local location. But she gave me 2 items, missed 2 items. Try to explain pick up but lady said go to service center. It's wasted my time

    keeps your pms done
    The value for your money is diffently with mobil and Walmart, its the best price around and it helps drivers keep up with their pm because having to get a pm done every 10,000 miles is really costly. We have been using this one for about 2 years and order it from Walmart.
