Is this a normal MPG?
Hello. I have an 2003 Alfa 147 1.9 JTD 16V (the 140HP version). I drive mainly in the city.
According to my trip computer, the MPG i'm getting is 56 = 5l/100km, which is perfect. But.... when actually driving, from 2160km to 2248km I've noticed I lost a whole partition on the fuel gauge. By simple math, with a tank of 60l, a partition should equal to 7.5l. 88km = 7.5l would put me at about 8l/100km or 35MPG city driving. I usually drive with a light foot, but I do floor it from time to time. Filling up 16 litres of fuel equaled to exactly 2 partitions and a bit, so my math is correct.
My car has an open thermostat and a probably very dirty EGR valve. Tires are 17inch, 225/45.
Is what I'm getting realistic or is there something wrong with it? 45MPG city driving was what I was expecting.
Are my mechanical problems a possible reason for this bad of an MPG? I can't brim the tank and do the test that way, no money to do so.
