    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
