Why do I need Fuel Doctor?
The potential for purchasing contaminated fuel is always present. An alarming amount of fuel storage tanks have some form of contamination or “dirty fuel”. How much and whether it will affect your vehicle depends on a lot of factors: age of the tank, lack of appropriate maintenance, and of course when the tank was last filled. Because you can’t see what goes into your fuel tank, you run the risk of transferring contaminants into your fuel system and causing damage to your engine every time you fill up.
What kind of damage can dirty fuel do?
Dirty fuel can cause damage to your fuel system and engine components simply by passing through the system. Microscopic particles of dirt and grime can clog fuel filters and injectors, reducing engine efficiency. In addition, water in your fuel creates the perfect environment for fungi to grow throughout your fuel system. These abrasive contaminants then pass through the system, causing additional, unnecessary wear and premature component failure, all at your expense.
But what is “dirty fuel”?
Dirty fuel is any fuel with contaminants in it. Around 80% of underground fuel tanks have water in them. Water provides the oxygen source for fungal spores (Cladosporium resinae) to grow and consume their favourite food—the hydrocarbons in fuel. Water from condensation also promotes flash rusting of fuel tanks, which flakes off into the fuel.

Don’t leave the health of your pride and joy to someone else…


What is Fuel Doctor?
Fuel Doctor is an Australian made fuel conditioner originally formulated to clean all types of fuel in inaccessible underground storage tanks. As such, it is effective in all diesel, petrol, and two-stroke fuel.
What does Fuel Doctor do?
Put simply… Fuel Doctor cleans and protects your entire fuel system while delivering optimum combustion and minimum pollution every time you use it. And, as an added bonus, it will also stabilise and extend the life of fuel in storage tanks or jerry cans for up to 5 years.
How does Fuel Doctor work?
Fuel Doctor is a proprietary formula of oxygenated molecules, which work to break down water and fungal material into sub-micronic particles, and emulsifiers which take those particles and disperse them into the fuel. It helps to protect your engine by lubricating any microscopic solid particles which enables them to pass safely through your fuel system and engine’s combustion process.
It will also dissolve carbon, gum, varnish, and other built-up contaminants in your fuel lines, fuel pumps, carburettors, injectors, and on valve faces, passing them through combustion safely.
Fuel Doctor is unlike any other fuel additive, because it’s used by the Fuel Doctors™ every day as a tool of trade so you can trust that it works.
Who makes Fuel Doctor?
Established in 1994, and 100% Australian owned and operated, Fuel Doctors™ specialise in cleaning fuel tanks. Many of the commercial underground storage tanks they were contracted to clean had no physical access points, so they needed to develop a new method of tank cleaning.
This led to the creation of the Fuel Doctor fuel conditioner, the industry-leading product which has been used in emergency generators, service stations, marinas, agricultural machinery, and all manner of vehicles for more than twenty-five years.
Researched, developed, tested, and used on a daily basis all in-house by the Fuel Doctors™ makes the Fuel Doctor fuel conditioner product unique in the industry and allows them to guarantee that, when used as directed, Fuel Doctor fuel conditioner will do no harm to your engine or fuel systems.
Can I see Fuel Doctor work?
Absolutely. Check out this video of Steve from Fuel Doctors™ demonstrating how Fuel Doctor works to Graham Cahill from 4WD Action. The entire video is worth watching as Steve explains what dirty fuel is, where it comes from, and what Fuel Doctor can do. But to see the demonstration, skip to the 8 ½ minute mark. Keep watching to see Steve clean the fuel AND put it in his own $200,000 vehicle.
Why should I buy now?
Every time you fill up, you take the risk of dirty fuel causing damage to your fuel system. Each tank of fuel you buy could contain enough water to flood your common rail direct injection system, as it only takes around 30ml. Yes as little as a shot glass! That top up on the way home from the shops could have just enough water and contaminants in it to completely ruin your engine.
When comparing the price of Fuel Doctor to the replacement cost of fuel pumps and injectors, Fuel Doctor becomes essential in quality assuring every litre of fuel you buy.
Every tank of fuel is potentially adding to the existing gunge and muck in the bottom of your fuel tank and increasing the level of contamination in the fuel passing through your engine.
The sooner you treat and maintain your fuel tank and system with Fuel Doctor, the sooner you can prevent further damage from dirty fuel and fill your tank with the confidence of knowing you’re protected.
