[bmw525iauto]

Hi guys, I recently purchased a BMW 525i 2005 Auto Petrol and after a few trips to the pump I have noticed that I'm getting around 16MPG . Now I understand that obviously its a 2.5 and an auto so sure it will use abit of fuel but I just wanted to know that this wasnt a cause for concern as since I purchased it the service overdue message has been on for around 4 weeks now .

Commute is about 5.6 miles each way.
