    Smooth running
    By  MARC,  a  Verified Buyer  from  Ennis, Montana  on  October 22, 2021
    Failed to verify captcha
    This product has increased my fuel mileage. We had a recent cold snap down to 16 degrees. The fuel was still fluid and no gelling took place. My Ford runs smoother and it accelerates much better when I have this on board. Much better.

    Significant increases in power and fuel economy!!!
    By  Mike,  a  Verified Buyer  from  Prescott  on  September 06, 2021
    Failed to verify captcha
    Recently I just drove to Wyoming from Arizona and back on a hunting trip. I've made this trip several times in the past. The trip varies in elevation from 4500 up to 11,000 ft. On this trip I started using the Diesel All-In-One and I saw significant increases in power and fuel economy, especially in the higher elevations where my truck used to struggle a bit. Great product and works as advertised!!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Diesel Fuel All In One
    By  GENE S.,  a  Verified Buyer  from  Lancaster, CA  on  August 24, 2021
    Failed to verify captcha
    I only use our 2014 RAM 3500 with a 6.7 Ltr. engine, to tow our fifth wheel RV. Keeping the engine clean is a must and so far, I get 12-14 MPG towing in 5th gear and on the open road empty, I get 29-31 MPG (with a 3.73/1 gear ratio. I couldn't get that without the injectors working really well. I only have 40K on the odometer but I'm still happy putting the fuel additive into the fuel every 4K miles.
    Bottom Line
    Yes, I would recommend this to a friend.
