We are proud to support motorsport with our newly blended sustainable fuels – the fuel of the future. We now have a full range of sustainable fuels with special additives to protect the fuel system and cylinder heads from valve seat recession.
Racing into the future
Goodwood announced at the end of last year, that all races at the 2024 Goodwood Revival will be running on fuels containing at least 70% sustainable components. Since then, our team has been busy developing and producing a range of new, sustainable race fuels that meet Goodwood’s criteria. We have so far developed four sustainable race fuels that have been extensively tested by leading engine builders.
FAS
READ MORE
Sunoco FAS is a sustainable racing fuel designed to maximise power, whilst meeting the new FIA Advanced Sustainable racing fuel regulations. Boasting an impressive oxygen content of 4.7%, its high energy level has already proven to release more power than traditional FIA 102 octane racing fuels. Meets FIA Appendix J, 252.9.3.1 Advanced Sustainable (AS) fuels.
S70L
READ MORE
Sunoco S70L is a leaded, high-octane, non-oxygenated race fuel containing 70% sustainable components for historic racing. The S70L simultaneously provides excellent valve seat recession and detonation protection, as it is kind to the fuel system. S70L does not contain ethanol.
S70LE8
READ MORE
Sunoco S70LE8 is a leaded, high-octane, oxygenated race fuel containing 70% sustainable components for historic racing. The S70LE8 provides excellent valve seat recession and detonation protection. S70LE8 contains ethanol as the oxygen carrier but has been boosted with additives to reduce the effect of the ethanol to the fuel system.
S70LE15
READ MORE
Sunoco S70LE15 is a leaded, high-octane, highly oxygenated race fuel containing 70% sustainable components for historic racing. The S70LE15 provides excellent valve seat recession and detonation protection. S70LE15 contains ethanol as the oxygen carrier but has been boosted with additives to reduce the effect of the ethanol to the fuel system. Fuel calibration is recommended due to the high level of oxygen in S70LE15.

What is a Sustainable Fuel?
What is the difference between Sustainable Fuel and Biofuel?
A biofuel is a fuel derived from renewable resources such as crops, algae, and forests—essentially, materials that absorb CO2 during growth and release it upon combustion. However, a significant drawback of biofuels is that they often compete with resources used for food production, or materials utilized in other essential industries such as furniture manufacturing. These types of biofuels are classified as Generation 1 fuels.
In contrast, sustainable fuels, typically categorized as Generation 2 fuels, are derived from waste materials generated during the production of usable products, rather than competing with them directly. Ethanol and methanol are commonly used as sustainable fuel sources, which can further be processed into hydrocarbons or utilized in their original form.
Moreover, sustainable fuels can also be produced through carbon capture processes. When the energy used in their production comes from renewable sources like wind, solar, or wave power, these fuels are termed e-fuels.
However, it’s worth noting that a common challenge associated with hydrocarbon fuels derived from bio components or classified as e-fuels is their typically low-octane rating, making them less suitable for high-performance applications such as racing.
