HYDRA FPB-77 FuelPlus Multi-biocide - Fuel System Cleaner | 100ml Treats up to 1000 Litres | Diesel Fuel Additive & Bug Treatment Ideal for Cleaning Diesel Fuel & Liquid Fuels, Removes Slime & Sludge

Bought as I use diesel powered hot jet wash so keep 20 litres in a Jerry can which can be sitting for months, I read that diesel can grow bacteria which breaks the fuel down into products harmful to the engines. This product stops this from happening and prevents the byproducts of diesel deterioration clogging up the injectors 1 millilitre treats 1 litre of fuel so it’s cost efficient- and goes a long way.

I think its an essential product to add to my jerry can of diesel. Good brand and product. Unfortunately like most other things its a bit pricey for the size you get but nevertheless worth it as a little goes a long way! The petrol one is also very good. Will buy again and again.

I really messed up and this product works, if I only knew about it sooner it could have saved me a lot of money. Super easy to use and a bargain

Happy with purchase

Used to treat diesel left in can for 3 months

Purchased this product, for my Kubota tractor and have found it very easy to use, with clear instructions as a fuel additive but too early to say just how effective it is
