Here is a sample purchased at a national brand truck stop that was delivering B20 fuel, meaning 20% Biodiesel and pulled from the trucks water separator.

B20 is a common blend because it represents a good balance of cost, emissions, cold-weather performance, materials compatibility, and ability to act as a solvent. Most Biodiesel users purchase B20 or lower blends from their normal fuel distributors or from Biodiesel marketers. Regulated fleets that use Biodiesel blends of 20% or higher qualify for Biodiesel fuel use credits under the Energy Policy Act of 1992.

B20 must meet prescribed quality standards as specified by ASTM D7467.

We are told that the state regulators passed the fuel. It is oblivious they did not use step one of a fuel test. LOOK AT THE FUEL. It is not clear and it not bright and would fail all tests as to quality immediately.

The dark layer at the bottom of the container is glycerine that has continues to drop out of the Biodiesel. This reaction should have been complete at the Biodiesel processor not after it was blended with diesel.

When this hit the engine fuel system, the engine stopped and the arguing started.

Here are the two most common (and costly) threats to your diesel engine:

1. Water: The Silent Destroyer

Water contamination is the leading cause of diesel engine problems—and it’s more common than most people realize.

Water can enter your fuel system in several ways:

• Contaminated fuel from suppliers
• Condensation inside storage tanks
• Poor handling or storage practices

Once water is present, things escalate quickly. Microbes begin to grow at the fuel-water interface, creating sludge and producing even more water as they multiply. Left unchecked, this contamination spreads throughout your system.

When water reaches your engine, the consequences can be severe:

• Steam formation under high temperatures
• Cracked or damaged fuel injectors
• Corrosion of internal components
• Complete system failure

Important: Damage caused by water in fuel is typically not covered by warranties.

2. Fuel Contamination & Degradation

Diesel fuel isn’t as stable as many assume—it has a limited shelf life. In fact, fuel can begin to degrade in as little as 30 days, especially when exposed to:

• Heat
• Air (oxidation)
• Moisture

As diesel breaks down, it forms:

• Gum and varnish deposits
• Sediment and sludge
• Darkened, unstable fuel

This degradation feeds directly into the water problem. More contamination means more microbial growth, which leads to:

• Clogged filters
• Reduced engine performance
• Unexpected shutdowns

If not addressed early, these issues can bring your engine to a halt.

Stop Problems Before They Start

The key to avoiding diesel engine failure is early detection and prevention.

If you suspect your fuel may contain water or contaminants, don’t wait for symptoms to appear. Testing your fuel now can save you thousands in repairs later.

Dieselcraft offers fuel test kits designed to quickly identify contamination issues—so you can take action before damage occurs.

Bottom line: Water and contamination don’t fix themselves—they get worse over time. The sooner you detect and remove them, the longer your engine will last. BUY HERE
