Review: A must have! - I have a 30 gallon storage tank for diesel for my tractor and this is a must have. 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.

## 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.
