Quick Answer
Add diesel cleaner to a nearly empty fuel tank before refueling to ensure proper mixing. Pour the entire bottle contents into the tank, then fill with diesel fuel. One bottle typically treats 40-60 litres. Drive normally after application. For purge cleaners, apply directly to fuel filter housing during filter changes following manufacturer instructions.
Expanded Answer (Simplified)
Using a diesel cleaner is a simple process that you can easily do yourself. Here’s a step-by-step guide:
1. Check the Instructions:
Before you start, always read the instructions on the product bottle. Different products may have slightly different recommendations.
2. Use at the Right Time:
It’s best to add the cleaner to a nearly empty fuel tank. This helps the cleaner mix thoroughly with the new fuel you’re about to add.
3. Add the Cleaner:
Pour the entire contents of the bottle into your fuel tank. Most products are designed for a single treatment.
4. Fill Up with Fuel:
Immediately after adding the cleaner, fill your tank with diesel fuel. The force of the fuel entering the tank will help mix the cleaner evenly.
5. Drive Normally:
You don’t need to do any special driving. Just drive your vehicle as you normally would. The cleaner will work as you drive.
For Purge Cleaners:
Purge cleaners are more concentrated and are used differently. They are typically used by professionals, but if you’re comfortable with it, you can do it yourself.
1. Change the Fuel Filter:
A purge cleaner is usually applied when you’re changing the fuel filter.
2. Fill the New Filter:
Pour the purge cleaner directly into the new fuel filter before you install it.
3. Install the Filter:
Install the new, cleaner-filled filter according to your vehicle’s instructions.
4. Start the Engine:
Start the engine and let it run for a few minutes to circulate the cleaner through the system.
Expanded Answer (Technical)
The proper application of diesel cleaner is critical to its effectiveness. The method of application depends on whether you are using a standard in-tank additive or a more concentrated purge cleaner.
In-Tank Additive Application
This is the most common method for applying diesel cleaners.
1. Timing of Application:
- Before Refueling: Add the cleaner to a nearly empty tank to ensure maximum mixing with the incoming fuel.
- During Refueling: If you forget to add it before, you can add it during refueling, but it may not mix as thoroughly.
2. Dosage and Treat Rate:
- Standard Dosage: Most products are designed as a one-shot treatment for a standard-sized fuel tank (40-60 litres).
- Treat Rate Calculation: For larger tanks or bulk application, calculate the treat rate based on the manufacturer’s recommendations (e.g., 1 ounce per 10 gallons).
3. Mixing and Distribution:
- Turbulence Mixing: The turbulence of the fuel entering the tank is the primary mixing mechanism.
- Vehicle Motion: The natural motion of the vehicle during driving will further aid in mixing.
Purge Cleaner Application
Purge cleaners are highly concentrated and require a more direct application method.
1. Fuel Filter Housing Method:
- Preparation: This is best done during a routine fuel filter change.
- Application: Fill the new fuel filter with the purge cleaner before installation.
- Engine Run: Start the engine and let it run at idle for 5-10 minutes to circulate the concentrated cleaner through the injection system.
2. Direct Fuel Line Method (Professional Use):
- Fuel Line Disconnection: The fuel supply and return lines are disconnected from the tank.
- Cleaner Circulation: The lines are connected to a container of purge cleaner, and the engine is run on the pure cleaner until the container is empty.
- Reconnection: The fuel lines are then reconnected to the tank.
Safety Precautions
Diesel cleaners are flammable and contain chemicals that can be harmful if not handled properly.
- Ventilation: Use in a well-ventilated area.
- Personal Protective Equipment (PPE): Wear gloves and safety glasses.
- Spills: Clean up any spills immediately.
- Storage: Store in a cool, dry place away from heat and open flames.
