A 170CDI mpg
Am new to the forum so greetings to everyone and happy new year.
I own a C 220 CDI 2001 and a A 170 CDI 1999.
On the A Class my mate is experiencing a very mpg ratio, lets say about 23 imperial mpg. What would help me a lot is list of the possible causes of this. The car has nearly 100k miles on the clock.
