Skoda Superb Engine Problems
How to reduce the fuel consumption in my Skoda Superb Scout?
While I’ll admit that an average fuel consumption figure of 12.4 litres per 100km is high for your car, there are a few things to consider here. By driving just seven kilometres each way to work and back, you’re probably running for half your driving time with an engine that is still warming up. Cold engines use a richer mixture and that means more fuel. Cold starts are a real problem for fuel consumption, and you appear to be driving on a cold engine for a high percentage of your daily run.
The other consideration is your average speed. You say that there’s no stop-start traffic conditions, but if you drive at urban speeds all the way to work, then you need to be looking at the official urban fuel consumption number which is 9.0 litres per 100km (the 7.3 litres figure you’ve quoted is for a mix of urban and highway running).
Even so, 9 litres per 100km is a lot less than 12.4 litres, so maybe there is something going on. Despite your reservations about Skoda’s politics, the best thing to do is to have the car electronically interrogated to see what, if any, fault codes appear. Only then can you really know what’s going on. Are you using the recommended 95-RON fuel? The wrong octane rating (RON) can have an effect on fuel consumption, as can a heavy right foot.
