750 Motor Club announced on 24 March 2026 that its partnership with Sustain would expand to include direct paddock fuel sales at race meetings.
The planned range combined Sustain products with conventional superunleaded fuel. The club described the conventional option as suitable for all its categories, while its product list restricted the 102 RON C50 fuel to Formula Vee. Sustain was also continuing as Formula Vee's title sponsor.
The supply programme involved AHS Motorsport at many meetings, with direct Sustain attendance or pre-ordered delivery at selected venues. The announcement included provision for Pembrey and a direct service at the October Birkett Relay at Silverstone.
