π§ͺ 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:
β
Up to 8.59 hours induction period improvement in B5 (5% biodiesel content & 95% conventional diesel)
β
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:
β Maintain fuel quality longer
β Reduce storage-related fuel problems
β Support cleaner fuel systems
β 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.
