Fuel consumption 900 II 2.0 with automatic

Hello Saabfahrer, I just have a Saab 900 Bj.96 with the 130 HP engine variant with automatic and air conditioning for testing.The car has run org.90 tkm and does not drive badly, a little sluggish but ok. Only the consumption with careful driving mode and off switch climate settles thus at 12,9 l / 100 km and that seems to me a little too much. How are your experience values or what this can be. All vacuum hoses are tight and also the AU test has no If the engine is wrong, please ask for help. Thank you and greeting Ralf
