Hydra Maximus Diesel Power Booster, we can’t claim it gives your car a jet engine, but with its instant pick-up, smoothness, and power it will certainly feel like one.

Modern diesel engines use high pressure fuel pumps with a pressure of up to 44,000 psi, the fuel is forced through tiny holes in the injector. This high pressure and tiny jet size create a very finely atomised mist of fuel.

Creating a fine fuel mist ensures that each molecule of fuel is surrounded by many molecules of air, which contains 20% oxygen. This ensures an efficient fuel burn.

When the vehicle is new, this process works very efficiently and the diesel engine operates at optimum performance as designed by the manufacturer.

However over a period of time (within 2,000 miles) deposits of carbon and unburnt fuel start to buildup in the injectors interfering with the correct spray pattern resulting in fuel wastage and higher emissions due to unburnt fuel leaving the engine.

Also diesel fuels with Cetane numbers lower than minimum engine requirements can cause rough engine operation. They are more difficult to start, especially in cold weather.


Many low Cetane fuels also increase engine deposits resulting in more smoke, increased exhaust emissions and greater engine wear.

Diesel engines can produce black soot or more specifically diesel particulate matter from their exhaust. The black smoke consists of carbon compounds that have not burned because of local low temperatures when the fuel is not fully atomised.

These local low temperatures occur at the cylinder walls, and at the surface of large droplets of fuel. At these areas where it is relatively cold, the mixture is rich (contrary to the overall mixture which is lean). The rich mixture has less air to burn and some of the fuel turns into a carbon deposit.

Using fuels which meet engine operating requirements will improve cold starting, reduce smoke during start-up, improve fuel economy, reduce exhaust emissions, improve engine durability, reduce noise and vibration.

Hydra Maximus Diesel Power Booster, has been designed to overcome all of these problems. Product reviews are outstanding and we don’t think that there is a better product on the market.

We can’t claim it gives your car a jet engine, but with its instant pick-up, smoothness, and power, it will certainly feel like one.


The powerful detergents in Hydra Maximus Diesel Power Booster prevents the formation of and also removes existing deposits caused by fuel decomposition and unburnt fuel. These deposits interfere with the performance of your diesel engine.

Injector deposits also mean uneven fuel flow, whereas 100% clean injectors give optimal fuel spray pattern resulting in a very finely atomised spray. This atomised spray means that each finely dispersed particle of fuel is surrounded by many molecules of air (20% oxygen) ensuring a more complete burn.

This in turn gives you much better fuel economy, as all the fuel is burnt, reducing emissions and improving engine durability. By reducing soot formation Hydra Maximus Diesel Power Booster also helps keep the diesel exhaust gas return valves clean.


Modern high pressure, direct injection diesel engines need high cetane levels to operate at their optimum efficiency.

Low cetane levels in diesel fuel can result in engine damage over time. When the cetane number of the fuel is low, engine knock and starting trouble can result from delayed ignition. Diesel knock can also occur during idling, giving poor warm up and white smoking after start-up.

Hydra Maximus Diesel Power Booster contains the maximum level of cetane booster to ensure that ordinary diesel is turned into Super +++ grade much better than you can buy at the filling station.

By decreasing the ignition delay, Hydra Maximiser Diesel Power Booster gives more time for the diesel fuel to burn and lowers the pressure inside the chamber. With a better fuel combustion at lower pressure, massive fuel and emission savings are possible.


Hydra Maximus Diesel Power Booster also contains lubricity improvers, that extend the life of injectors and the fuel pump. These lubricants work in very cold climates and do not raise the sulphur level of treated fuel.

Test results give HFRR Wear Profile of less than 300. Our lubricants also reduce the friction in the cylinder thereby improving the coefficient of friction helping fuel economy. Hydra Maximus Diesel Power Booster protects your valuable fuel systems, prevents engine malfunction and engine failures.


Independent Laboratory Tests proof that treated diesel still meets EN590:2009 the current EU standard for diesel fuel, therefore your vehicle warranty is not affected by using Hydra Maximus Diesel Power Booster.


Hydra Maximus Diesel Power Booster gives a much smoother, quieter engine with much more power, better torque, better fuel economy, fuel remains stable whilst harmful emissions are reduced to a minimum.


Dose Rate: Use at 2ml to every 1 litres of fuel.

Modern engines after only 20-30 hours, can lose as much as 5% of their power and fuel efficiency through deposits building up inside the injectors. These deposits effect the smooth flow of injected diesel fuel, reduces your fuel economy and makes cold starting of your engine more difficult.


Cars, vans, trucks, buses, trains, boats, generators, earth moving vehicles, military vehicles etc. It can be used in all types of diesel engines including 2 and 4 stroke.


By utilising new developments in detergent technology, Hydra Diesel Power Blast ensures a complete internal engine clean, down to molecular levels. Existing carbon and unburnt fuel deposits are rapidly removed from injectors, valves etc., giving the engine as new performance.


The problem with diesel fuel used in boats, generators, farm vehicle etc., is that very often this fuel remains in the fuel tank for extended periods before being used. As many of us are aware this fuel starts to degrade after only 4 weeks, leading to long term problems and inefficiencies (in a car it is normally used within a week or two). Hydra’s stabiliser and biocide active ingredients ensure that your fuel remains sweet and stable for much longer.


Modern high pressure direct injection engines use precise fuel metering through narrow shaped spray channels. Injector deposits mean reduced fuel flow. 100% clean injectors give optimal fuel spray pattern, this results in a very finely atomised spray pattern.

This means that each finely dispersed particle of fuel is surrounded by many molecules of air (20% oxygen) ensuring a more complete burn. Giving better fuel economy, reduced emissions and improved engine durability.


Hydra Diesel Power Blast’s nano-molecular catalyst ingredient introduces additional oxygen to the fuel, this catalyst lowers the auto-ignition fuel temperature, giving a longer burn time. You are now burning all the fuel instead of blowing some of it through the exhaust system where it will help clog the Exhaust Particle Filter if fitted. The net result is a quieter and smoother running engine with more mpg and reduced exhaust emissions.


Hydra Diesel Power Blast Injector Cleaner also contains lubricity improvers that decrease fuel pump and injector wear issues, they work in very cold climates and are very low in sulphur. Test results give a HFRR Wear Profile of less than 300. These lubricants also reduce the friction in the cylinder thereby improving the coefficient of friction and help improve fuel economy.

Hydra Diesel Power Blast Injector Cleaner protects your valuable fuel systems, prevents engine malfunction, and engine failures. Protects the fuel performance properties of EN590:2009 as well as specifications such as colour, heat of combustion, pour point and cloud point. Also prevents fuel starvation, damage to injectors and engines. Can be used in all grades of diesel fuel including B0 diesel and biodiesel fuels.

I was sceptical at first
Monday, 11 January 2021  | 

Regarding my recent purchase, this is the third or fourth time that I have ordered the product from you. I must confess that I was sceptical at first but decided to give it a try. It does exactly what it says it does which is quite rare these days for a product, but more than this your customer service is excellent. I will not hesitate to recommend you and your products to my friends and colleagues and have already done so.

Kind regards

My feedback is always the same. As per many positive reviews of your product, you used to supply these bottles with a reinforced ziploc bag which was perfect for storing them (once opened) in my car. I haven't been able to find a similar bag anywhere else and wish you would return to including one with each bottle purchased.

Saved me 3000
Sunday, 6 September 2020  | 

I had a problem with white smoke puffing out my exhaust on start up. Subaru said it was diesel injectors and quoted 3000 because its an engine out job. I bought the diesel injector cleaner and after 1 month of use the smoke has all but gone. I was averaging 500 miles to a tank and since using this I'm now getting around 630 miles to a tank. I'm not saying everyone will be as lucky as me but for the cost of this product it's been amazing. Pretty much saved my car from the scrap heap.

Many thanks for the very quick service. I should have brought the 500 ml brought the cetane boost for that price.also purchased diesel fuel cleaner. Have put both in vehicle and hopefully it's working it's magic as we speak.

Ordering and delivery is simple and efficient as usual.

As for the product itself I have now increased the dosage to 2.5ml per litre (rather than the recommended 2.0/litre). And this is a lot better.

I have seen fuel consumption improve by around 10% overall. And my car (9 year old Audi Q5) is running like new.

The only problem that remains is your awful dispensing bottle. I decant the product into little (200ml) fruit juice bottles with sports cap and this works very well.

all the best

This stuff is brilliant. I do between 3 -400 miles per week in my 59 plate Ford TDCi with 115k on the clock. I've used the Hydra Injector Cleaner over the past 12 months and I rate that, this is even better.
Engine is quieter with smoother power delivery, it just keeps pulling (especially at the top end, perfect for my A-road commute).

The only downside is that its addictive, after using it once I never want to run my car without it.

Ques : I own a 2011 1.5d Nissan Qashqai. I have used your Diesel Power Blast in the past (still using with each tank fill) and found it to be effective and gains noticeable immediately. I do believe it has offered me slightly better MPG and a more responsive throttle.

Kindly advice which is the best additive you offer to draw even more performance/mileage out of my engine.

I notice your other offerings, namely:

- 2 Ethylhexyl Nitrate HYDRA FUEL CETANE BOOSTER +Biodiesel Additive; and

- HYDRA Fuel 2 EHN 2 Ethylhexyl Nitrate Cetane Enhancer Fuel Additive

Are the above offerings more potent and can offer better performance over the Diesel Power Blast? What do you recommend?

Ans: We have a new product Hydra Maximus which gives the maximum performance increase of any product on the market. Beats any premium fuel hands down. We are getting rave reviews for this product.

I am using this in my own Mercedes E350 which has Brabus chip fitted, with this additive in the diesel fuel, my car is now faster without the chip switched on than it was previously with the chip switched on. The engine feels silky smooth with a real push in the back when accelerating. This car has always suffered from turbo lag, taking about a second for the turbos to spool-up, now the power is instantly available as soon as I floor the throttle.
