  • NATO Part No: NSN 6850-99-238-3567
  • Converts NATO Jet A-1 and JP-8 to Diesel equivalent
  • Contains extra lubricants, which counter the fuel drying effect of Jet Fuel (Kerosene)
  • Contains the best cetane booster, 2-EHN 2-Ethyl Hexyl Nitrate + lubricants
  • Boosts cetane rating from 4 to 8 points, improving performance and economy
  • Improves cold starting, reduces smoke, engine noise and harmful emissions

Brand:  HYDRA



The cetane number is an index of the ignition point or combustion quality of fuel, fuels with cetane number lower than minimum engine requirements can cause rough engine operation. They are more difficult to start, especially in cold weather, and many low cetane fuels, increase engine deposits resulting in more smoke, increased exhaust emissions and greater engine wear.

Standard NATO aviation kerosene JET A-1 and JP-8 normally has a minimum cetane number of around 43. But the optimum cetane value requirement for most diesel engine vehicles such as tanks and trucks is around the mid to high 50s.

HYDRA S-1750 will increase the cetane number of jet fuel by up to 8 points depending on base quality of fuel being treated, It provides an economic route to meeting quality specifications and a platform for creating a fuel suitable for all diesel engines.

By reducing the ignition delay period HYDRA S-1750 improves fuel combustion resulting in easier cold starting, reduction in white smoke, harmful emission reduction and reduced noise from engine. Better fuel combustion means improved fuel economy.

HYDRA S-1750 also contains extra lubricants which counter the fuel drying effect of the Jet Fuel (Kerosene) boosters, preventing excessive wear on internal engine components, ultimately extending engine lifespan.


Usually used with JET Fuel Additive dosing systems or, in emergencies, can be added directly to fuel tank then top up with new fuel. Fuel tanks being treated should be at least 10% full.

Dilution Rate: 1:1,000 (1 litre m³) can be used at up to 1:500 (2 litre m³).

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. Modern diesels donít like the bio diesel coming through the pumps nowadays and this stuff has helped with better power delivery and fuel economy.
