## Questions & Answers

**Q: What is the shelf life of this product?**
A: They are sealed so expect a shelf life of a few years.

**Q: How many oz for 26 gal fuel tank**
A: Each of these bottles treat 30 gallons.  The approximate dosage is 1 ounce for every four gallons.  If your fill up is about 16 gallons put in 4 ounces (1/2 bottle).  If your fill up is 20 gallons put in 5 ounces.  Basically take the gallons added to the tank and divide by 4.  Round up or down to the nearest ounce.

**Q: Is this also an anti gel?**
A: Yes,  it includes Cold Weather Protection – improves diesel pour point up to 40°F (22°C), and cold filter plug point by up to 25°F (13°C), depending on base fuel

**Q: Should I had it to my empty tank, then fill it with fuel, or fill first, then dump in the bottle?**
A: I pump a few gallons in if empty (which I don't recommend for fuel system health) them complete the fill up with diesel fuel.

### ⭐⭐⭐⭐⭐ It improved my diesel system performance
*by R***D on October 24, 2025*

Recommended by the dealer for my newer model GMC diesel pickup and so far it has proven itself to work. When the engine seems to be running a little more sluggish or the DEF system doesn't seem to be operating as well I add a bottle of this, to the fuel tank at fill up and everything seems to improve. I've had my check engine light come on for emissions system issues a couple times and this has helped resolved the issue. It's a little bit expensive so I add it once every 4 to 6 weeks at the most.
