I've had my (UK spec) 3.2 engine, now 140K miles old and never been apart since 1994 in my 1973T 911.
In all those years it has had Shell's finest petrol, in recent years 97 octane.
The nearest Shell station has changed over to ESSO, and they sell 99 octane.
The car seems to run quite a lot smoother in traffic or motorway and in this hot weather the engine runs about 2 degrees hotter in general.
Was the ROW 3.2 engines tuned to 99 octane/5 star fuels?
