pdf Datasheet (Hydra Fuel Cetane Booster) - Click here

diesel fuel made from natural oils and fats has a much lower cetane number than diesel made from hydrocarbon sources.

Diesel engines require a minimum cetane number to run correctly. In Europe, diesel fuel is manufactured to a European Union specification i.e. EU 590. Fuel meeting this specification has a minimum cetane number of 51 and premium diesel fuel can have a cetane number as high as 60.

Therefore, if you are making diesel fuel from a natural source it is necessary to add a cetane booster such as Hydra 2-EHN Cetane Booster to your fuel, 2-EHN is the standard cetane booster, approved by all governments and used worldwide.

Hydra Fuel Cetane Booster delivers an increase in Cetane number to your Diesel and MGO fuel. It will increase the cetane number by up to 4 to 8 points depending on the quality of fuel being treated.

Hydra Cetane Booster provides an economic route to meeting quality specifications and a platform for creating premium fuels. Diesel bug treatment improves fuel combustion by reducing the ignition delay period resulting in easier cold starting, reduction in white smoke, harmful emission reduction and reduced noise from the engine. Better fuel combustion means improved fuel economy.


Add to fuel tank then top up with new fuel. Fuel tanks being treated should be at least 10% full.  Usual dose at 1:1,000 to 1:500 depending on quality of fuel and performance increase required.

Dose Rate - 1:1000

Add 50ml Hydra Cetane Booster to 50 litres of fuel.

Dose Rate - 1:500

Add 100ml Hydra Cetane Booster to 50 litres of fuel.

seat Leon FR 170PD diesel
Monday, 4 February 2019  | 

Since owning my Leon when the outside temperature is below 6c it starts to get more of a challenge to start. Spent £1000's trying to sort this out and the final component change was a Valeo 2kw starter which made a massive difference. However even though it starts much quicker it was still running lumpy especially under 2c. Since using this product it fires up and runs totally smooth. When warm and ideling it feels like the car isn't running it's that smooth amazing product and great value for money.

I had some problems with my VW 1,6 TDI Diesel engine after the Motorsoftwareupdate (VW-Diesel-Skandal). After using your additives the problems (strong diesel knock, bad gas acceptance) are away and the engine run`s very well again!

Works a charm

Has made a world of difference in my Mazda. Modern diesels donít like the bio diesel coming through the pumps nowadays and this stuff has helped with better power delivery and fuel economy.

Ques : Can that be used on the car with the dpf filter?

Ans. Yes, it can be used in diesel fuel tank of car with DPF filter.

Ques : Apart from the price, what's the difference between your Cetane Booster and Power Blast additives? I've been using a Chemsearch additive (K Gard) in my Shogun and it makes a very significant all-round improvement.

Ans. The cetane booster is purely that, i.e. it increases the cetane rating of the fuel you are using. The diesel and petrol power blast products as well as containing cetane/octane boosters, also contain detergents which clean your complete fuel system. Including injectors and exhaust components, ensuring that your engine receives finely atomised fuel, ensuring a much better fuel burn (each molecule of fuel is surrounded by molecules of oxygen). Your engine is now smother and has more power / torque with reduced fuel consumption.

Ques : Hello, I want to buy the Cetane booster and the Lubricity Booster; these products have a time limit for conservation beyond which they lose efficacy and performance?

Ans. Both products have a shelf life of 2 years.

Ques : Hello, I'm just wondering if this product is safe to use with biofuel diesel?

Ans. Yes, this product is safe to use with biofuel diesel.

Ques : I recently purchased your cetane booster, would it be beneficial to use this product at the same time to increase lubrication and cleaning, or do you think that would not be a good idea. I ask because I have been led to believe cetane boosters reduce the lubrication slightly in the diesel fuel ?

Ans. We Would recommend to use Hydra Diesel Power Blast, which is a complex product that already includes a cetane booster and lubricant.

Ques : My maths is rubbish at this time of day. Can you tell me how many ml I would need to put in a 50 Litre diesel tank on both the normal ratio and the higher dosage ratio ?

Ans. 50ml of Hydra Cetane Booster treats up to 50 Litres of fuel in normal ratio and in higher dosage ratio 100 ml of Hydra Cetane Booster will treat up to 50 Litres of fuel. Please make sure fuel tanks being treated should be at least 10% full.
