⚠️ Water contamination can destroy modern high pressure common rail fuel systems. The right approach is simple: de-emulsify, separate, filter, and protect. Large amounts of water should always be removed with proper filtration technology.

🧪 Did you know biodiesel blends can oxidize and degrade faster than conventional diesel fuel?

Recent oxidative stability testing on 4+ Premium showed significant improvements in fuel stability for both B5 and B10 biodiesel blends.

At our enhanced treatment rate, testing demonstrated:
✅ Up to 8.59 hours induction period improvement in B5 (5% biodiesel content & 95% conventional diesel)
✅ Up to 7.14 hours induction period improvement in B10 (10% biodiesel content & 90% conventional diesel)

Oxidative stability testing measures how long diesel fuel can resist oxidation before it begins to rapidly degrade.

In this testing, untreated biodiesel blends begin oxidizing sooner, while fuel treated with 4+ Premium resisted oxidation significantly longer.

What does that mean in the real world?

For fleets, generators, bulk fuel storage, agriculture, and seasonal equipment, stronger oxidative stability can help:
✔ Maintain fuel quality longer
✔ Reduce storage-related fuel problems
✔ Support cleaner fuel systems
✔ Improve long-term equipment reliability

As biodiesel content continues to increase across the industry, fuel stability matters more than ever.

Maintain the integrity of your diesel fuel with 4+ Premium.

Satiate Your Fuel Tank with 4+ Premium.

Bulk diesel fuel's quality can deteriorate during storage.

Water contamination, oxidation, and poor combustion quality can creep in over time — especially in large storage tanks.

4+ Premium keeps your fuel in check:
• Stabilizes diesel during storage
• Separates and controls water
• Improves cetane for cleaner burns
• Adds lubricity for system protection

And it costs less than you think:

👉 4L = treats 9,109 L → $0.0209/L
👉 10L = treats 22,768 L → $0.0197/L

That’s about 2 cents per litre to maintain fuel integrity across your entire tank.

Cheap insurance for expensive fuel.

The Elephant in the Room! As a qualified Diesel Fuel Injection Technician since 1970, I have witnessed significant advancements in fuel systems, with electronics playing an increasingly crucial role. However, one constant remains: water and particulates in fuel continue to cause approximately 75% of fuel system failures. Despite this, diesel equipment owners persistently overlook the root cause, incurring substantial repair bills. To minimize downtime and reduce costs, I invite you to follow my articles on Fuel Cleanliness at dieselservices.com and discover how to safeguard your equipment.Just follow the Fuel Solutions prompts.

A MATCH MADE IN HEAVEN:

Bulk diesel storage tanks 🤝 4+ Premium

If you’re storing thousands of litres of diesel, you’re sitting on a major investment. The problem? Time, moisture, and instability slowly degrade fuel quality.

That’s where 4+ Premium comes in:

✔ Stabilizes fuel for long-term storage
✔ Drops out water with de-emulsifying chemistry
✔ Boosts cetane for better combustion
✔ Enhances lubricity to protect your equipment

Now, do the math:

• 4L jug treats 9,109 L → $0.0209/L
• 10L jug treats 22,768 L → $0.0197/L

For ~2 cents per litre, you’re protecting your entire fuel supply.

When it’s time to fuel up, you’re not guessing what’s in your tank — you know it’s clean, stable, and ready to perform.

Protect the fuel. Protect the equipment.
