Which Fuel Octane
When I asked the OPC when ordering my car in December he said they recommended 98 octane for all cars irrespective of the vehicle spec
Now ask them what they put in when they fill it when they do the PDI. I bet it’s the cheaper alternative

I've actually seen this happen, brand new car getting a tank full of 95 octane before collection. Good fresh 95 wont harm the engine although it will loose you that last 1% of performance on full throttle. Fresh fuel is as important as octane. A fill of 98 thats been lying around in a service station tank for six months due to slow sales will be no better than 95. When I raced I was always careful to make sure my fuel was fresh as possible, often asking the station owner when they had last filled the 98 tank and using anything left over after the race in the lawnmower. Much the same as we wouldn't perform well on out of date beans neither does an engine on out of date fuel.

With the current lockdown, my GTS hasn't turned a wheel since mid December. Not that I'm likely to use full throttle for more than the odd second or so but I imagine the fuel in the tank will eventually deteriorate just as if it had been in a garage's tank.Rab J wrote: ↑Thu Jan 28, 2021 9:40 am

I know our OPC in Tewkesbury use the very local 'Morrisons' to do their initial fill up of fuel before delivery, as this local garage only offers 95 octane unleaded there is no debate on what fuel your new Macan will have in its tank on collection!
My sales exec recommended using three tanks of '95' and then one tank of '98' I must admit it has been hard to tell the difference in performance or MPG but have followed that advice since collection a couple of years back without any complaints so far.

I just don't see any reason not to use the good stuff, but that's partly due to running a Turbo PP which is mapped to need the octane more than others.
