Wide wheel upgrade & mpg

I've just gone from 10.5 at the rear to 11.5 and my mpg has plummeted. Is this normal?

 

I used to get about 260 miles from a full tank (TT BPU) and now I'm lucky to get 220. I thought 260 was bad enough but 220 is just daft.

Is that all local stop start miles? Recently on a trip to Belgium with my family I managed 380miles to one tank of fuel. This was with me taking it easy & mostly dual carriageway/motorway driving over 3 days which included a lot of starting the car and some local driving.

 

Mine is a TT6 (previous NA6).

 

So 220 seems very low. Have the 02 sensors been cleaned? Are you running rich perhaps? If you are driving leaded footed everywhere then that is expected as you'd know having her for nearly 10 years ;)

10liters must be reserve then. I filled it up from empty and i only got 60 liters in it.

 

Yep I think that includes the reserve.

 

I just know the JSpec's have a 70L tank whilst the UK's have a 80L tank.

Yeh I'll get the sensor checked next time it's in the garage. I was expecting less mpg but not that much!

 

Also I have recently gone auto to 6 speed, but for that I would have thought I'd get better mpg not worse.

 

Oh and yes I might have been driving a bit harder now I've got a different set up, just to check things out like ;)

Most likely it is you enjoying the new setup :D

 

I had an auto before and without a doubt the fuel is better on the manual.
