Official Distributor for Fuel Doctor in the Philippines.


Fuel Doctor’s state of the art formulation converts free water and microbial growth into microscopic particles. These particles are dispersed evenly throughout the fuel and harmlessly processed through combustion to the exhaust.

About Fuel Doctor

Fuel doctor is a Fuel System Cleaner, Conditioner, Stabiliser. Initially formulated in 1994 to assist in the cleaning in inaccessible underground fuel storage tanks, Fuel Doctor is a blend of oxygenated solvents and emulsifiers, formulated to disperse and protect against the accumulation of aerobic fungi growths and sulphate reducing bacteria in all hydrocarbon fuels and storage systems.

Fuel Doctor converts accumulated moisture (condensation) fungal growths and their excreta into microscopic particles whilst dissolving gums, varnish and asphaltenes. These contaminants are permanently suspended in the host fuel allowing harmless passage through injection to combustion and exhaust with zero detrimental effects. Fuel Doctor’s state of the art formulation has detergent and viscosity characteristics that improve lubricity, extending pump and injector life. Composed of Carbon, Oxygen and Hydrogen, Fuel Doctor cannot contribute to airborne pollution and is Ad-blue compatible. Oxygenated molecules within Fuel Doctor promote and increase thermal efficiency whilst minimising carbon, soot accumulation and particulate emissions. Increased filter, pump and injector life with enhanced fuel, power and economy are the immediate benefits from the use of Fuel Doctor.

Q & A

Did you know there’s water in your diesel fuel?

1. How does condensation take place in diesel fuel tanks?
Diesel fuel tanks are always subject to water condensation because diesel fuel, unlike gasoline, has no vapour pressure to displace air. When a fuel tank is warm, the air expands and is forced out. As the tank cools at night, humid air is sucked back into the tank and water condenses out on the cooler tank walls.
There are many ways that water gets into fuel. Water is often present in the fuel when you initially buy it. Quite often it finds its way into your tank through condensation resulting from temperature rising and falling throughout the day. Diesel fuel is highly “hygroscopic”, meaning it absorbs water from the air.
2. Where does the water come from?
The water comes from an open fill port, a defective tank, or an open drum during rain or transferred from another water contaminated tank.
3. What are the side effects of having water contaminated into fuel system?
The side effect of water is that it rusts steel and iron components, forming loose particles of iron oxide. The rust particles can quickly clog fuel filter. Micron sized and smaller rust particles may pass through: Fuel injectors which ruining fuel injection spray patterns.
4. Can water ruin my fuel injector?
Yes, it will cause damage to your injectors leading to excessive wear and premature failure of injectors and fuel pumps.
The injector life will be reduced by about half. When water passes through an injector, it is immediately vaporised and turned into steam. Because this occurs at high pressure, it will eventually damage the injector tips. This tip damage will prevent the injector from creating the desired fuel spread pattern. Water is also the culprit that spurs the growth of fungi and bacteria at the bottom of the fuel tank. Some of the bacteria in the tank release acid byproducts. This acid causes corrosion within the fuel system. Inorganic debris such as rust, dust, sand and other particulars usually find their way into fuel during the transportation and delivery process from the refinery to the fuel pump. This dirt is abrasive and causes excessive wear and tear on the engine parts. Adhering fuel preventive maintenance programd is a simple and inexpensive alternative to the cost of repairing severely damaged high pressure pumps, injectors and pistons.

Frequently Asked Questions

First time usage?
For vehicles with fuel tanks of less than 500 ltrs, where practical it is recommended to initially drain or pump any free water from the tank bottom, then treat at one litre Fuel Doctor per 100 ltrs or less of tank capacity per 100,000 kilometres the vehicle has travelled.
Example: vehicle has a 80 litre tank and has travelled 200.000 kilometres, treat with one litre of Fuel Doctor on two consecutive tanks, then ongoing at one millilitre per litre of fresh fuel.
Over Treating?
It is impossible to over treat with the Fuel Doctor, while we recommend following the treatment guidelines, Fuel Doctor is formulated so that it will not harm your fuel system or engine if you use more than recommended amount.
Common rail diesel, diesel particulate filter?
Empirical and anecdotal evidence shows that Fuel Doctor decreases particulate material (unburnt fuel), numerous charter boat companies and bus companies have noted a substantial decrease in soot accumulation on the rear of buses and the transoms of boats, consequently consistent use of Fuel Doctor will decrease particulate build up in DPF’s.

Numerous tilt ray operators in Brisbane have noted that constant use of Fuel Doctor has dramatically reduced the frustrating regeneration cycles that have disrupted their cash flow.

What does it do with the water and fungal material?
Fuel Doctor breaks the water and microbial molecules into sub micronic particles that are encapsulated into the detergent (Fuel Doctor) matrix allowing them to pass harmlessly through the fuel system to combustion.

"Have used other injector cleaners with no results or improvement, After using your product, It’s remarkable."

Ray Turner

"Thank you for your quick response in rectifying the contaminated diesel. Our machines were up and running for first thing Monday morning"

Peter Leonard

"When I read on the bottle of Fuel Doctor that I would be impressed I thought here we go again but what the heck, I'll give it a go. I'm not just impressed I am bloody impressed."

Dean Francis


Fuel Doctor will have zero detrimental effect to oxygen sensors, diesel particulate filters or catalytic converters, O-rings, carburetor internal rubbers or gaskets, high pressure common rail diesel or petrol injectors or injection components.

Fuel Doctor will stabilise fuel quality for up to 24 months for petrol and 60 months for diesel.
