More and more garages are no longer selling straight unleaded fuel, but predominantly E10. Whilst an A7 should run on virtually anything, the best alternative is Super unleaded 98 octane without ethanol. I dont use lead substitute additive.
I must admit I have never had any problems with fuel ageing, but it obviously exists. Now you've got the car running, do another compression test with the engine properly warmed through & throttle open. 70psi seems low to me. My RP saloon with 37 head gives 125psi hot.
