HVO 100-drivstoff represents a revolutionary hydrogenated vegetable oil that burns cleaner than conventional diesel whilst delivering identical performance. Unlike traditional biodiesel, HVO undergoes hydrogenation treatment rather than esterification, creating a paraffinic fuel molecularly similar to fossil diesel but with up to 90% lower carbon emissions. This synthetic fuel works in existing diesel engines without modification, offers superior cold-weather performance compared to biodiesel, and doesn’t deteriorate during storage. For UK motorists seeking sustainable driving solutions, HVO 100 provides genuine environmental benefits without compromising power, torque, or reliability.

HVO 100 overview
Hydrotreated vegetable oil represents the pinnacle of renewable diesel technology. The production process involves subjecting renewable feedstocks to high-temperature hydrogenation in the presence of catalysts. This treatment removes oxygen molecules, creating pure hydrocarbons chemically identical to petroleum-derived diesel.
The raw materials include waste cooking oils, animal fats, and sustainable vegetable oils. Manufacturing plants in Scandinavia, particularly Finland, lead global production. The resulting fuel meets EN 15940 specifications rather than traditional diesel standard EN 590.
Typical retail price hovers around £1.70 per litre, roughly 10-15% more expensive than conventional diesel at the pump. Commercial fleet operators often negotiate better rates through bulk purchasing agreements.
Advantages of HVO 100:
- Drop-in replacement requiring zero engine modifications
- Superior cetane number (70-90 versus diesel’s 51-55) ensures cleaner combustion
- Virtually no sulphur or aromatics content
- Exceptional oxidation stability prevents fuel degradation
- Reduces particulate matter emissions by up to 33%
- Lower NOx emissions compared to fossil diesel
- Functions perfectly in all temperatures down to -30°C
Disadvantages of HVO 100:
- Premium pricing limits widespread adoption
- Limited availability at UK forecourts currently
- Requires sustainable feedstock certification to guarantee environmental credentials
- Slightly lower energy density (approximately 3-5% less than fossil diesel)
- May cause slight reduction in fuel pump lubrication in very old systems
Ideal drivers for HVO 100:
Fleet operators pursuing carbon reduction targets benefit most from HVO adoption. Commercial vehicles covering high annual mileage see genuine emissions reductions without operational disruption. Construction equipment operating in emission-controlled zones gains compliance advantages. Owners of classic diesel vehicles appreciate the fuel’s cleaner-burning properties that reduce carbon build-up.
Our mechanics at Autopartspro have observed that vehicles running HVO 100 consistently show cleaner injector nozzles during routine servicing, with noticeably less carbon accumulation on intake valves and combustion chambers.
Biodiesel (FAME) overview
Fatty acid methyl ester biodiesel emerges through transesterification, where vegetable oils or animal fats react with methanol. This chemical process creates methyl esters—the actual biodiesel molecules—plus glycerine as a by-product.
Production occurs globally from rapeseed, soybean, palm, and recycled cooking oils. The UK primarily uses rapeseed-derived biodiesel blended into standard diesel at B7 levels (7% biodiesel, 93% petroleum diesel).
Pure biodiesel (B100) rarely appears at retail pumps due to compatibility concerns. When available, pricing sits around £1.55 per litre, though most motorists encounter only pre-blended fuel at standard diesel prices.
Advantages of biodiesel:
- Established production infrastructure throughout Europe
- Better lubricity than ultra-low sulphur diesel benefits fuel injectors
- Competitive pricing when blended at low percentages
- Renewable resource reduces dependency on fossil fuels
- Biodegradable and less toxic than petroleum diesel
- Lower carbon emissions than conventional diesel (50-70% reduction)
Disadvantages of biodiesel:
- Poor cold-weather performance causes fuel gelling below 0°C
- Hygroscopic properties attract moisture, promoting microbial growth
- Degrades rubber seals and gaskets in older vehicles
- Oxidation during storage limits shelf life to 6-12 months
- Requires more frequent fuel filter changes
- Can dissolve existing fuel system deposits, clogging filters
- Reduced energy content delivers 5-8% worse fuel economy
Ideal drivers for biodiesel:
Agricultural operations producing their own feedstock can utilise biodiesel economically. Vehicles operating in warmer climates avoid cold-weather problems. Operators with modern diesel engines (post-2010) designed for B7 compatibility experience fewer issues. Budget-conscious drivers benefit from lower costs when available at discount.
According to Autopartspro specialists, biodiesel above B10 concentrations should be avoided in vehicles older than 2010 unless manufacturer approval exists, as fuel system degradation and injector fouling become genuine concerns.
Key differences between HVO and biodiesel
The fundamental distinction lies in chemical structure. HVO consists of paraffinic hydrocarbons virtually identical to fossil diesel molecules. Biodiesel comprises fatty acid esters with oxygen content that creates compatibility challenges.
Production methods diverge significantly. Hydrogenation removes oxygen, sulphur, and impurities from HVO feedstocks at high temperatures (300-400°C) and pressures. Transesterification creates biodiesel through relatively simple chemical reactions at atmospheric pressure.
Performance characteristics separate these fuels dramatically. HVO functions flawlessly in arctic conditions whilst biodiesel gels in mild frost. HVO remains chemically stable for years; biodiesel oxidises within months. HVO works in every diesel engine without modification; biodiesel often requires manufacturer approval beyond B7 blends.
Environmental credentials differ too. HVO achieves 90% carbon reduction when produced from waste materials. Biodiesel delivers 50-70% reductions but faces sustainability questions regarding land use for crop-based feedstocks.
The molecular uniformity of HVO ensures consistent combustion characteristics. Biodiesel’s variable composition depending on feedstock creates performance variations. This explains why HVO meets paraffinic diesel standards whilst biodiesel requires separate FAME specifications.
Compatibility considerations
Understanding vehicle compatibility prevents expensive repair bills. HVO 100 works in virtually all compression-ignition engines built since the 1980s. Manufacturers including Volkswagen, Mercedes-Benz, Ford, and Volvo explicitly approve HVO use without warranty implications.
Check your owner’s manual for EN 15940 paraffinic diesel approval. Vehicles displaying this standard can safely run HVO 100 continuously. Classic diesels benefit from HVO’s superior lubricity and cleaner combustion, though extremely old mechanical injection systems may need seal upgrades.
Model year considerations matter less for HVO than biodiesel. Any diesel from 2000 onwards accepts HVO without concerns. Pre-2000 vehicles should undergo fuel system inspection, particularly checking rubber components in the fuel supply unit.
OEM specifications increasingly reference paraffinic diesel. European manufacturers recognise EN 15940 alongside EN 590 in technical documentation. Japanese brands remain more conservative, though mechanical compatibility exists regardless of official approval.
Installation notes for HVO conversion prove straightforward—simply fill your tank. No modifications, additives, or special procedures apply. The fuel’s cleaning properties may initially loosen existing deposits, so consider changing your fuel filter after the first tank if switching from heavily contaminated conventional diesel.
Biodiesel compatibility requires greater scrutiny. Manufacturers typically approve B7 (7% biodiesel blend) as maximum for warranty compliance. Higher concentrations risk fuel system damage in vehicles not specifically designed for FAME operation. Always verify manufacturer guidance before using B20 or higher blends.
Final verdict on HVO versus biodiesel
Choose HVO 100 for maximum environmental benefit without operational compromise. Fleet managers pursuing genuine carbon reduction whilst maintaining full vehicle capability find HVO unmatched. The premium pricing becomes negligible across high-mileage commercial operations when factored against reduced maintenance and extended component life.
Select biodiesel blends (B7-B20) for cost-effective renewable fuel when operating in temperate climates. Agricultural businesses with captive feedstock supplies gain economic advantages. Vehicles with explicit high-blend FAME approval from manufacturers suit biodiesel well.
Avoid high-concentration biodiesel in older vehicles, premium German diesels with sensitive fuel systems, or any application involving prolonged storage periods. Cold-climate operators should reject biodiesel entirely unless winter-grade formulations with cold-flow additives are guaranteed.
For daily driving in the UK, HVO represents the superior choice when accessible. The fuel delivers identical performance to conventional diesel whilst slashing emissions dramatically. As forecourt availability expands, HVO adoption makes environmental and mechanical sense.
Frequently asked questions
Can I mix HVO 100 with conventional diesel in my tank?
Yes, HVO blends seamlessly with fossil diesel in any proportion without adverse effects. The paraffinic structure ensures complete miscibility. Many operators transitioning to HVO gradually blend increasing percentages, though immediate 100% switching causes no problems in compatible vehicles.
Does HVO 100 require different service intervals or special oil?
No, standard maintenance schedules and conventional engine oils remain appropriate. HVO’s cleaner combustion may actually extend service intervals by reducing soot contamination. Some operators report longer periods between oil filter changes, though manufacturer recommendations should govern service timing.
Will HVO damage rubber seals and fuel lines like biodiesel can?
No, HVO proves chemically inert towards elastomers and plastics used in fuel systems. Unlike FAME biodiesel, paraffinic diesel contains no oxygen molecules that attack rubber compounds. Modern and vintage diesel vehicles alike experience no seal degradation from HVO use.
Where can I buy HVO 100 fuel in the UK currently?
Availability remains limited but expanding rapidly. Commercial fuel suppliers serve fleet customers nationwide. Retail forecourts in London, Scotland, and major cities increasingly stock HVO. Certas Energy, Crown Oil, and specialist renewable fuel distributors offer bulk and retail options.
Does HVO affect fuel economy compared to standard diesel?
HVO delivers approximately 3-5% lower energy density than fossil diesel, theoretically reducing range slightly. Real-world testing shows negligible differences due to HVO’s superior combustion efficiency. Most drivers notice no measurable change in miles per gallon between HVO and conventional diesel.
