    I am curious to know what you guys believe is the best motor oil for a 6.2 L with over 75,000 miles. One guy recommended Chevron's Delo 400 to me. What do y'all use? Has anyone tried any of the Max life products out on the market? /forums/images/graemlins/k5.gif

    I can tell you that at Caterpillar engine development we used Chevron Delo. However, I think Rotella, Delo, and Delvac will all work equally good.

    I use Rotella T 15W-40. I have heard Amasol is a good oil, but haven't had the change to try it myself.

    I've used Rotella 15W40 and am using Penzoil 15W40 without any problems.

    You got some responses here, I use Rotella, and if you want more do a search, there was a thread 2 months ago that had all the pros and cons of each oil used and change intervals too.

    Any diesel rated oil with the latest rating of CF-4 is fine for use. Don't use any oil if it doesn't carry the C (for compression ignition) rating.

    I use Rotella T myself, it's one of the most widely used diesel oils out there.

    You hit the nail right on the head. To many people use oil that is not rated for a combustion engine.

    If memory serves Rotella is produced by Shell right?

    Some once told me that Rotella poured easier than Dello, but the story went that it was -40 outside. Not sire if that was true or a just another line the parts store guys try and feed ya.

    I run Mobil Delvac 15W-40. Used to run Rotella T. I use the Mobil because I can get it in 2.5 Gallon(10 quart) containers at the local Meijers. Cummins holds 12q, backhoe holds 10q. When I had a 6.2/6.5 "only" took 8 qts and 2 1 gal jugs of Rotella T fit the bill.

    Those empty Mobil jugs work great for waste oil. Plastic doesn't break down and has a large opening too dump the oil. 5 gallon gear oil pails are a pain, too much weight and too small hole to drain fast enough.

    The best- Mobil Delvac 1 is one of the best. Do a search on it and you will see it's pretty good. Also, try Bobistheoilguy. It's a great site on oil.
    BTW, Wallmart has Shell Rotella T 5W40 syn. for 13 bucks a gal.. It ain't as good as Delvac but it ain't too shabby.
