Well heres the thing, i have been trying to work out if its gona save me money if i get a desiel and i need a bit of help with peoples mpg readings that they get, im looking into getting a MY08 A3 2.0 Tdi 170 or 140, so the figures from these will be a greay help. Here are my journeys and mpg i currently get, would appritiate if anyone could give me rough mpg on what you would expect from the same journeys, cheers. Journey 1 - 12 miles there, currently get between 36-38 mpg by the end of the 12 miles, journey back is exactly the same. Roads are A road and some town driving. Journey 2 - 16 miles there, currenty getting 35-38mpg. A roads and town driving, and a couple of miles of country roads. Journey back is the same & same figures. Journey 3 - 20 miles, currently getting 37-40mpg. A roads for the majority and about 3-4 miles of town driving, journey back is more B roads with an mpg of 38-40. Roughly do about 100-150 miles at weekends, mixed roads. Btw, i drive sensibly for all journeys, even do 60-65 most of time on duel carrigeways. And my annual milage is prob about 15,000-20,000. All help will be appritiated, sorry if anyone doesnt understand it i'll try explain further if you dont. Thanks again.
