Dilution Rates

Shock / Initial Dose: 1: 3000 (30 ml per 100 litre fuel)

For already microbe contaminated Fuel System

Add to the existing fuel tanks at recommended dosage to kill off all damaging microbial growth.

Refueling Dose: 1:10000 (10 ml per 100 litre)

To Protect Clean Fuel System

Add the recommended refueling dose in the tank before topping up with fresh supply. Ensure the addition of treatment refueling dose every time the tank is topped up.

Fuel Tanks

Fuels left for storage in fuel tanks will always contain some water. The amount of water present will gradually increase with time. The longer the fuel is left undisturbed the more water it will contain.

As freshly refined fuel cools down, its water solubility decreases. Henceforth, moisture, which was previously dissolved in the fuel begins to drop out of the fuel. This process continues throughout the fuel’s cooling process even during transport.  As fuel’s specific gravity is lower than that of water, as dissolved water condenses it tends to drop out of fuel, accumulating in tank bottoms and in pipeline low-points.

Fuels are usually stored for a considerably long time before it reaches the customer therefore will always contain some water. Biological diesels such as (FAME) tend to hold more water than the conventional diesels. The accumulated water is an ideal environment for the microbes to thrive and contaminate the fuel severely compromising the consistency and quality of the fuel.

Thus technical challenges are faced by Company’s in bulk storage and in vehicles, since all fuels types especially low sulphur and biological diesel can exhibit particular problems which cause difficulties in operation.

The fuels in storage, especially bio-diesel can absorb moisture from its surroundings, this can lead to microbial infestation and fuel bug issues. Fuel tanks/storages in hot countries can accumulate nearly 0.1% water depending on the volume and type of the fuel as a result of condensation during long-term storage.

Microbial infestation including growth of microbes such as moulds, fungi and bacteria if left untreated during long term storage, can severely affect the fuel quality. This microbial attack leads to degradation of fuel, decreased in lubricity as fuel additives are broken down by the harmful microbes.

Very prompt delivery. Treated my boat diesel tanks at end of summer. This winter should be a good test for the biocide. Should know in the spring.

Worked Well! No Problem Since...
Thursday, 5 January 2017  | 

During winter my diesel motor home isn’t used for about 6 months, we usually keep the diesel tank full to eliminate any problems with condensation.
Because diesel now contains a percentage of bio diesel, it had unknown to us been creating diesel bugs over the winter period, they caused us to breakdown in within 150 miles of setting off from the Scotland.
The mechanic advised us that we had a clogged primary filter. He replaced the filter and £275 later we were back on the road. He told me that the clog was due to algae that had grown in the tank and recommended I start using Hydra FuelPlus Biocide.
So I bought some and put it in the tank. We travelled about another 150 miles and broke down again, I checked my primary fuel filter cartridge and it was almost clogged again.
I called Hydra’s technical help line, their expert explained that my problem was a microbial growth problem and I would have to keep cleaning my primary filter until the dead sludge stopped coming through. He told me that it should soon all be gone and sure one more clean and the system was OK.
Since then I always use Hydra when I refuel and I have not had a problem since.

Ques : I have purchased a 250 ml HYDRA FUELPLUS BIOCIDE .  It will be used in a small fuel tank on our 24ft yacht the tank we think holds about 6 gallons. How much should I use ?

Ans. The measuring chamber at the top of the bottle has numbers on each side these are ml to put the correct amount of additive into the fuel. First Treatment - for 100 litres of fuel in your tank would add 30ml i.e. 1x25ml and 1x5ml shot. After the first treatment you dose for the fuel you are adding to the tank i.e. you add 100 litres.

Ques : Can this be used for kerosene (heating oil)?

Ans. Yes.

Ques : I have just received two bottles of fuel plus biocide. I have an old Citroen xsara with a tank capacity of 44 litres. Recently the filter was found to be covered with black sludge which has been cleaned. How much additive should I use on first application please ?

Ans. Add 3ml Hydra FuelPlus Multi Biocide to 10 litres (1:3,000 - 300ppm) of fuel.

Ques : Hi, what other additive (antifreeze and/or injector cleaner) is compatible with this?

Ans. Hydra Diesel Power Blast – Injector Cleaner

Hydra Petrol Power Blast – Injector Cleaner

Hydra Winter Cold Flow – Diesel Antifreeze

Ques : Hi, I guess this is acceptable to use in white diesel & doesn't upset the customs men when dipping fuel tanks ?

Ans. This will have no effect on Customs & Excise dipping tanks, they are looking for a red indicator dye, none of our fuel additives contain any dyes.
