I also use the same brand that’s for gasoline for my tank that fuels my lawnmower. I’ve personally used diesel that was well over 2 years old with this product and it runs just as good as if I’d bought the diesel that day. It’s much better than stabil because you can actually add it to fuel that’s already been in storage, and it’s still effective. With stabil, you must add it when you purchase your fuel. Review: Time proven product - Pri has been around for a long time. I use this for long time storage of diesel fuel. Keeps it fresh and clean. I will also use this in my older truck and equipment to help with lubrication since the fuel is all low sulfer. ## Features - Improves fuel efficiency - Better Mileage - Higher performance - #1 Diesel Stabilizer - Cuts Smoke & Soot ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0029012P6 | | Best Sellers Rank | #240,599 in Automotive ( See Top 100 in Automotive ) #179 in Fuel Additives | | Brand | PRI | | Customer Reviews | 4.7 4.7 out of 5 stars (91) | | Date First Available | May 7, 2009 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.08 pounds | | Item model number | 117590 | | Manufacturer | OEM Replacement Parts | | Manufacturer Part Number | PRI 16D | | Model | PRI 16D | | Product Dimensions | 5 x 3 x 7.75 inches | ## Images ![Diesel Fuel Treatment PRI 16D - Image 1](https://m.media-amazon.com/images/I/81TSmfdhZIL.jpg) ## Questions & Answers **Q: how many gallons does a 16 oz. bottle treat?** A: I think it treats 250 gallons but the products website has detailed info and is a good read. I love the pre-g for gas. I don't run the truck for weeks at a time so it is good insurance. The pre-g refreshes and keeps gas for at least 3-4 years. Refreshes winter gas. So far I like it. I hope that helps. Good luck **Q: What is the shelf life of both the gas and diesel product?** A: Well that question depends on a couple factors. One, your location, I've found that the closer you are to sea level the less condensation and breakdown occurs. Second, how you store it, say jugs or a tank in the ground. The fuel itself....gas, figure a year, possibly more - untreated. Diesel, a couple years, again, untreated. PRI-D and G, keeps that breakdown from happening. Remember with diesel, if its been sitting for a long time to filter it, it at times has the capacity to grow slime. Just use a nylon knee high, that works well. Hope this helps some. **Q: Is this good for storing diesel over the winter. Does it stop algae and other diesel storage problems?** A: I add it to my 80 gallon tank in my shed as I fill it. I use maybe 25 gallons a year. I haven’t had algae problems but, the biggest thing is moisture - if you keep the water out of the fuel - you’ll be good. I also add lubricity & cetane boost. **Q: if u over fill with this product,,, any issues?** A: Depends on how much you overfull, say a lot, like 2 or 3 times the amount. All you need to do before you use it is cut it with more untreated fuel. Hope this helps some. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A must have! *by M***E on July 10, 2025* I have a 30 gallon storage tank for diesel for my tractor and this is a must have.
