Stanadyne Performance Formula Diesel Additive – 6-Pack Of 64oz Bottles (38566)

If you run a diesel, you know how important clean fuel and good additives are.

This is a bulk pack of Stanadyne Performance Formula—six 64-ounce bottles to keep your tanks treated for a long time.

It’s a multi-action formula: it boosts cetane for better starting, prevents corrosion, and has anti-gel properties for those colder months.

Great for pickups, big rigs, or equipment.

Just be aware of the Prop 65 warning—like many chemical products, it has stuff on the list.

But for keeping your injection system happy and performing, this is top-tier stuff.
