Excessive fuel consumption

[Danieldj]

Hi everyone 

I've recently bought the outback from late 2015 2.0d and I'm happy with the car the only thing that's bothering me is the fuel consumption. The computer says that is around 8.5l/100km or 33mpg in your figures but when I done the calculation manually (fill and calculate) I've realized it's 11.5l/100km or 24.5mpg. Apart from that is drinking the diesel like there's no tomorrow everything seems fine. Just to mention previously I had bmw 530d 3.0diesel with 193hp and that car was averaging 7.6l-100km(37mpg). I understand this is 100+ kilos heavier than the bmw and awd and automatic (bmw was a manual) but still I think it's too much for 2.0d correct me if I'm wrong 

 

Thanks in advance

I've resolved the issue, it was obvioulsy down to the quality of diesel because when I changed the petrol station the consumption went down to around 9l/100km
