CP113 PRI-D Diesel Treatment - 16 oz.

Pri-D and Pri-G are my go-to fuel stabilizers. I've used them both for years especially the Pri-D diesel stabilizer. I buy diesel bulk when it's cheap and use it all year long when the prices are higher. I treat it every year and have never had any gel or go bad on me even when stored 3 or 4 years. Great Product. Pricey, but it's good and even better if you can get it on sale. Gasoline does not store as long as diesel. You can stretch diesel out for 7-8 years if you treat it yearly. Gas will only go 2-3 years with this treatment. But that's still pretty impressive.

Been using this for 11 years now- my filters are absolutely clean. Don’t even know why I bother changing them every 200 hours.works as described

Great additive. I saw test results a while back on fuel that was treated with this and it was impressive.

Great product at a good price. Ours had leaked during shipping. Not a ton but had to wipe up the bottle.

I've been using the Pri-G (gasoline) product for years and it's my subjective opinion it is superior to other gasoline stabilizers. Some equipment I have, e.g. commercial pressure cleaner, I only use every year or two and it would start right up with the Pri-G (not so much with the Sta-Bil product). As regards the Pri-D fuel stabilizer, one of my several diesel Mercedes cars is 33 years old and had a sticking fuel indicator (perhaps sludge in the tank??). Use of the Pri-D fuel stabilizer seemed to free up the fuel tank apparatus so that the fuel indicator now works appropriately. I now use the Pri-D in all my diesel cars.

Very good product

I own a 2002 Dodge Ram 3500 5.9 Cummins, my truck runs fine, but after adding this within a few miles, once it had made it through my fuel system, I felt a smoothness I am not sure how to describe, I also noticed I could get the RPMs up to 3k much easier in each gear the further I drove… at first before it had cycled in through the fuel system I started taking each gear to 3k RPMs and in some gears it took quite a bit of time… and 4th or 5th I didn’t even think it was going to hit 3k… I just kept doing this… running through each gear and taking each gear to 3k… after I felt that smoothness kick in I literally saw each gear go straight of to 3k without effort… I saw the difference this product right in front of my eyes… by time I had done this… 4th and 5th went to 3k with the same easy all of them did… I recommend this product to revitalize your engine and I recommend you do as I did and watch how the RPMs noticeably change from the moment you get in and drive the vehicle until it starts to work its way into the system you will see the RPMs increasing more smoothly and swiftly… I have no doubt that if you have an older vehicle you will see and feel your engine get younger and more tenacious.
