  • Boosts Cetane Numbers in Diesel & MGO Especially Bio Diesel.
  • Improves performance, economy also increases Cetane up to 4 to 8 Points.
  • Improves cold start and reduces diesel engine knock.
  • Ideal Cetane booster for bio-diesel producer.

Bio 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 cetane number by up to 4 to 8 points depending on 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 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.

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!

Has made a world of difference in my Mazda. Modern diesels don’t like the bio diesel coming through the pumps nowadays and this stuff has helped with better power delivery and fuel economy.

Hydra Fuel Cetane Booster (Ideal for Bio-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.
