Here is your problem - rpm range did not go below 3000... so the engine must eat.
Keep it below 3000 and it will give you much better results.
The engine is just fine at 1500 rpm pulling in 4th gear.

But not much fun, lol.


My 2000S gets terrible mileage. Turns out the nut connecting the steering wheel to the seat has a leadfoot.

Driving these cars at 1500 RPM s not really a good thing

Date to elaborate as to why?

I support my statement with... AT shifts mapping. If Porsche believed their engines are not supposed to experience low RPM they would upshift at 3000 RPM range, yet they upshift much lower.

Sure, I am not talking about running WOT at 1100 rpm - if you need power, rev it. But for everyday use - keeping between 1500-2500 is just fine.
