It took some time from mods and my is220d driving without any problems. Fuel consumtion is less than 5 liters in motorway , in city driving short distance with my "small webasto" about 8 litres. After calculation bc showing more than in real consumtion. On Christmass i made some test , fully tank my car, drove 221 km on motorway, speed 60-70 km/h cuz of road works about 40 km, after this about 100 km/h. When i made 221 km i drove on petrol station and tank 10,11 of diesel. As i said my bc shows more
Iam still modifies fuel by adding Kleen flo , or archoil.
On vacation in August on 18 inch wheels i made similar test but speed was about 160 km/h fuel consumtion was about 7.25 litres.
