Hey guys, I'm new to everything here so if i mess up then sorry My Subaru is a 2007 Legacy 2.5L Sedan --> CarJam reckons the model is a 2.5i AUT LUX model (not sure what AUT means) and it should be getting 8.9L/100km. but anyway.. I got my first Subaru a month and a half ago and was warned about the fuel consumption that may come with it. After a few weeks i did notice quite a high consumption which i tested to be 12.8L/100km mix of traffic, a bit of motorway and hard driving. Was thinking of selling my current car and buying the Legacy 2.0L GT with the intent to get slightly better consumption (around 10-11L/100km which is what my mate claims to get) and upgrade in performance - Is it worth upgrading to the 2L GT for a slightly lower fuel consumption average while also getting an increase of power?
