Drop-in replacement for diesel

IHO is compatible with BS 2869 Class I, which means it’s fully miscible with diesel, so there’s no need to run your tanks dry of existing fuel. You can refuel and go!

IHO is one of the UK’s leading fuel products authorised for use by many of the top boiler companies.

It is not to be used as fuel for a road vehicle, off-road vehicle, vessel or any other machinery that is not an excepted machine.

Fuel system cleanliness, corrosion protection & reduced emissions

IHO contains a multifunctional additive that provides fuel system cleanliness, corrosion protection and chamber deposit control.

Delivery within 48 hours

With a vast network of depots and tanker fleet, we ensure seamless access to IHO with deliveries made within 24-48 hours of order.

Cost-effective heating fuel

IHO is a fully rebated product and is therefore a most cost-effective alternative than diesel for commercial heating.

Please note, it is strictly prohibited for use in road vehicles, off-road vehicles, vessels and any other machinery that is not an excepted machine.
