Sustain Fuels announced a direct paddock supply service for 750 Motor Club's Silverstone International meeting on 15–16 August 2026. The supplier's 13 August notice said this would be its first direct on-site appearance of the season, following supply through service partner AHS Motorsport.
The planned service included Supersport 99, a conventional 99 RON E5 petrol advertised at £1.95 per litre including VAT. Sustain explicitly distinguished that product from its sustainable fuels. Its 102 RON Racing C50 product was also due to be available, with use restricted at that time to Formula Vee under the relevant regulations.
The dispensing rig was intended to supply cars and fuel containers directly. Larger drums required advance arrangements, while existing orders placed through AHS Motorsport were to remain in place.
