I had my Seat Leon 1.6tdi 2014 serviced a week ago and from the first day after the service until now the MPG is terrible around 20 mpg less can't even get it over 60mpg prior to the service the worst I got was 63mpg but I was consistently getting 68-75mph and on occasion 80-86mpg. Not sure why this has happened any ideas? Wrong oil type? Wrong fuel filter?

Hi I have checked both spontaneous and average, but I normally go by the average. Similar journeys and same types distance and road surfaces, I did the exactly the same journey the difference was 25mpg less which I think is pretty obvious something not right. If it had been 1-5mpg difference I wouldn't really notice but 25mpg is a big difference the hasn't been over 60mpg and struggles to get even 55mpg mostly 45-50mph now when before my worst was 63-65mpg
There are three averages! - which one did you used to use, and which one is it on now?
1. long term?
2. since refuel?
3. current journey?
Try toggling between them?
Everyone knows (should know) TDI's use 507 spec oil which is 5w30 or 0w30 - There is no way using the wrong oil would loose you 25mpg!
Was this a main dealer - or an independent?
