Frequently Asked Questions

Q: How do I select the best size of Fuel Enhancer for my engine?

In general, for bigger engine sizes, larger fuel enhancer sizes are recommended.

As a general guideline, for on-road vehicles one can use the following:

  • Small car: F24
  • Medium car: F28
  • Van, 4×4: F34
  • Light Truck: Double F34
  • Light truck / small size bus: F44
  • Truck (500+ HP) / bus: Double F44

 

A bigger fuel enhancer will have a bigger impact on the quality of the fuel and therewith the performance of the engine. If you know that fuel is of low quality in your region, then a larger size fuel enhancer is recommended.

A limiting factor for the size can be the space available in the chassis, around the engine. It is recommended to look at the space where the fuel enhancer will be installed, prior to ordering the fuel enhancer.

 

Q: What benefits can I expect on the performance of my engine?

The general benefits that you can expect are:

  • Cleaner emissions
  • Reduced fuel consumption
  • Reduced maintenance costs
  • More engine power

 

The exact extend of these benefits depend on various factors including engine type, fuel quality, how the vehicle/engine is operated, how the engine is already impacted by injector fuel deposits, etc.

 

Q: When will the fuel enhancer need to be replaced?

The durability of the fuel enhancer depends on various factors including the size of fuel enhancer installed for the engine type, the fuel quality, how the vehicle/engine is operated, etc. In South America, where Euro 3 diesel is used, large trucks have reported to be still functioning beyond 250,000 km.

For boats, you can use 2,500 hours operation as guidance assuming that you use a primary filter and water separator before the fuel enhancer and the secondary filter after.

It is recommended to change the fuel enhancer after 5 years maximum.

Q: Will the fuel enhancer impact the warranty of my engine or vehicle?

This is possible. If your engine or vehicle is still under warranty conditions from the manufacturer, it is strongly recommended that, prior to installation, you check with your engine supplier how installation of the Black Eagle Fuel Enhancer may impact your engine manufacturer’s warranty. Please note that Black Eagle and all other representations are not liable for potential change in the engine manufacturer´s warranty.

 

 

Q: Where/how should I fix the fuel enhancer?

The optimal location for the fuel enhancer to be fixed is behind  the primary filter and water separator (if applicable) and prior (and close) to the engine fuel filter, so a minimum extension of the fuel line is required. It should be fixed to a stable frame or chassis completely vertical and without movement. The fuel line and Enhancer should be installed at safe distance from parts that generate heat, friction or movement.

 

Q: Can I change the Fuel Enhancer from one engine to another?

Once installed, the device cannot be changed from a diesel to a gasoline engine. It can be changed from a gasoline to a diesel engine however, after being, emptied, dried for two days, and purged with 4 liters of diesel.

 

Q: The fuel filter of my vehicle is installed at a location where I cannot install the fuel enhancer (this generally the case with gasoline engines). What should I do?

You should install a fuel filter between the fuel enhancer and the injector system. You can use a universal fuel filter, or identify the recommended fuel filter for your vehicle.

 

Q: Does the material of the fuel line matter?

The most important is to use material that is qualified for use with fuel and that is certified for 20 bar working pressure. Both with fabric-reinforced rubber injection hose or polyamide 12 (aka Tecalan) fuel hose are commonly used materials.

 

Q: Can I use the fuel enhancer with bad fuel?

This depends. If the question refers to a low quality, or slightly degraded fuel, then absolutely yes the fuel enhancer is the perfect device to save your engine from harm and get a better performance. However, if your fuel is far gone, for example infected with microbes (bacteria, fungi and yeasts that feed on the fuel, leaving visible acidic by-products, along with the slime created by their own biomass), then it is better to reach out to a professional company to empty and clean the tank and fuel system, and use the fuel enhancer with clean fuel to prevent problems in the future.
