Sweet stuff
Just had 3 gallons of this Delvac Extreme 15-40 put in my 2016 Ram CTD. No more clicking and diesel clattering. Really quieted the engine down.

    Great Diesel Oil
    Put 3 gallons in my RAM Cummins 6.7. This is my second time using this oil. My labs came back great after my first run of 7500 miles and lots of heavy towing. TBN was still 5.5, could have run it 10,000 miles. This oil is now on my favorites list!!

    My engine is running like new
    Great value for the price. I was looking for a motor oil that would perform higher mileage intervals and this is the one

    NOT A FULL SYNTHETIC
    Don't be fooled, this product is a synthetic blend not a full synthetic. I contacted Mobil to be sure.

    Great Synthic Oil
    I have a 2005 GMC Sierra 3500 with Duramax Diesel that has 43000 miles on it, I had been using regular 15W-40 Regular DENO oil in her since I purchased it new back in 2005, Then last year I switch to a Full Synthetic made by BG Oil, and as soon as I put it in, my engine started to make a noisy clicking sound, I ran it for 4000 miles and sent in a Oil Sample to have it tested and they notified me that the oil was showing high levels of Copper and Zinc, and that I should have it checked, I pulled the drain plug and let all the BG oil drain out over nite and dumped 10gts of Mobile Extreme 10W-40 full Synthetic in her plus new filter, and as soon as I started it up the clicking sound was going, Then after I had 3000 miles on the new Mobile Oil I sent a Sample to Black Stone, and the Sample came back "A-OK".
