Ally is not restricted to supercars..
In actual fact I would be surprised if a supercar wouldn't make 2000H.
Cirrus SR22T's are 'approved' to run 94UL- at much higher fuel flows. With rich of peak ops only. ( full FADEC)
And no. I'm not a rich of peaker.
The issue is not just vapour lock, lead is also a lubricant.
