Case Study: Fuel Testing

This video covers the vehicle testing process used to test biodiesel fuels in a refuse collection vehicle.

The test assessed standard diesel (base fuel for comparison), a B20 fuel (FAME) (made from 100% used cooking oil), and a Hydrotreated Vegetable Oil (HVO) (made from waste vegetables and oils).
HVO is known as renewable diesel and FAME is commonly known as biodiesel. Unlike FAME, HVO uses hydrogen as a catalyst in the creation process and it does not require methanol.

The results of this test showed a reduction in NOx (70% reduction), particulate matter (PM) (33% reduction) and WTW CO2 (12% reduction) compared to a regular diesel.

Drop-in fuels such as HVO and gas-to-liquid (GTL) can reduce the Wheel-to-Wheel (WTW) CO2 impact of commercial vehicles and are supported by commercial vehicle manufacturers.

Currently the fuels are limited in supply but there are companies currently working to provide a supply to London operators.

Quotes from the vehicle manufacturers



“All of the current DAF range of vehicles is suitable for operation with parafinnic diesels that conform to EN15940, including HVO and GTL.
One of the key benefits of these fuels is their compatibility with existing vehicles without the need to adapt maintenance regimes. The clean-burning properties of HVO and GTL and the carbon-saving potential of HVO provide an exciting opportunity to significantly reduce the impact on the environment from both existing and new vehicles.”

Dennis Eagle

“HVO fuel has no impact on service intervals or routines with the Euro VI step C engine and also does not affect warranty as long as the fuel is to TS 15940.”


“We accept 100% HVO on all of our Truck range except the Cursor 9 engines at the moment. Where we accept HVO, warranty is unaffected. This applies to vehicles built in 2017 onwards and is not retrospective.”

Mercedes-Benz Trucks

“2nd Generation Biodiesel: Up to 100% HVO, Biomass To Liquid (BTL), Gas To Liquid (GTL), Coal To Liquid (CTL). Second Generation Biofuels conforming to prEN15940 standard. OM934, OM936, OM470 & OM417 from Production Month February 2016. No change to maintenance intervals, warranty or other conditions. Not possible for OM473.”


“All New Generation Scania products will be capable of running on HVO provided it meets fuel quality requirements. New range is scheduled to be rolled out over a two year period.”

VOLVO & Renault Trucks

“Volvo Trucks has a full range of engines ranging from 210hp to 750hp certified at Euro VI for use with HVO to EN15940 with no impact on service demands or intervals.

Renault Trucks has certified its entire engine range to operate with HVO, meaning that all Renault Trucks and with Euro VI Step C engines can use HVO without any adaptation or impact on service requirements.”
