Fuel Consumption Worse After Service 1 & 2
Not sure why, but my Z4MR fuel consumption is worse post service 1 & 2 (done at the same time) than what it was pre-service. Went from an average of 21.7mpg to 18.1mpg and doesn't appear to be improving.
Has anyone else experienced this? Car has 83000kms (51500 miles) on it. |
