Frequently Asked Questions on HVO (Hydrotreated Vegetable Oil)

HVO general information

What does HVO stand for?

HVO stands for “Hydrotreated Vegetable Oil”.

How is HVO different to a diesel fossil fuel?

HVO fuel is clear and different to a diesel fossil fuel in that it is almost odor-free.

Are the sustainable diesel fuels HVO and biodiesel (rapeseed oil) the same?

No. The fuels differ in the processing of the raw materials used and as a result, they are two different fuel types. 

The HVO fuel pursuant to EN 15940 is exclusively approved for Wacker Neuson products.

Is HVO produced from palm oil?

No. Since the introduction of the European Renewable Energy Directive (RED II) in 2023, the use of palm oil is prohibited in bio-fuels.

Which raw materials are used for the manufacture of HVO?

Plant-based raw materials, residues and waste products are used in its manufacture. Within the framework of the European Renewable Energy Directive, these must fulfill the strict sustainability criteria regarding environmental aspects, such as carbon footprint, protection of forests, etc. 

Which HVO fuels can I use in Wacker Neuson products?

HVO fuel must fulfill the provisions of DIN EN 15940 for paraffinic diesel fuels.

All Wacker Neuson equipment and machines with Stage 5 diesel engines are approved for the use of HVO fuels pursuant to EN15940. This includes excavators, wheel loaders, wheel and telehandlers, as well as vibratory plates, vibratory rammers and rollers.

How do I know whether my machine is suitable for the use of HVO? 

All Wacker Neuson machines that are fueled with HVO ex works have a corresponding sticker near the tank filler neck. 

Essentially, all Wacker Neuson products are approved for HVO. Among older vehicles it is the combustion engine Stage 5 that is suitable for HVO; however, the fuel-containing components (seals, filters, hoses, etc.) must be tested for HVO compatibility. 

Alternatively, you can contact your Wacker Neuson distributor on-site. Here you can find your nearest Wacker Neuson distributor: https://locations.wackerneuson.com/lf/

Sustainability

Why is HVO environmentally-friendly? 

When using fuels made from hydrotreated vegetable oils, the operation of a combustion engine is carbon-neutrally. 

Exclusively renewable raw materials are used for the manufacture of HVO. The combustion of HVO results in less greenhouse gases. Overall, carbon emissions can be reduced by up to 90 percent. And HVO is biodegradable.

Application

Do I need to consider anything in particular when using HVO, e.g., converting the engine?

No, because the essential changes have been done ex works. 

With older vehicles, the fuel-containing components (seals, filters, hoses, etc.) must be tested for HVO compatibility. All Stage 5 combustion engines of older vehicles are suitable for HVO. 

There are no additional requirements in terms of storage or use when compared with fossil diesel. 

Can I also operate a machine with HVO, which has already been in operation for several years?

All Stage 5 combustion engines of older vehicles are suitable for HVO. 

The fuel-containing components in older vehicles, like seals, filters and hoses, must be tested for HVO compatibility. Please contact your Wacker Neuson Customer Services to confirm the compatibility of your precise machine model.

Do the service life and performance of the machine change with the use of HVO fuel? 

HVO fuel has not exhibited a negative impact on the service life and maintenance intervals of the engine. 

The energy content of HVO can be less. A negligible reduced output can therefore depend on the engine used and the specific application, yet this does not lead to a significant output loss.

Can I operate the engine with several different fuels?

Yes.  You do not have to decide upon one fuel, but you can operate the same combustion engine with either pure HVO, an HVO-diesel mixture, or a standard diesel. However, frequent changing between the fuels should be avoided. Please refer to the product’s service notice. If you have any questions, please do not hesitate to contact your Wacker Neuson distributor.

What are the additional benefits to using HVO?

By using HVO, you can reduce the carbon emissions on your construction site by up to 90 percent without needing to change your machine fleet.

HVO fuels have a shelf-life of several years.
