I know this has been covered in many threads however i am d*mned if i can find info regarding this. And yes i have tried various search words/phrases.
I suspect the MAF maybe in need of a spring clean! My consumption has been gradually increasing over the past few months way beyond that normally associated with winter. I used to regularly get 55-57+mpg which increased to 54-56 ish when I had new tyres fitted. This increased further to 50-51 with the onset of cold weather however it is now only 48 mpg. I use quality fuels and am currently on a tankful of Total Excellium diesel with no apparant improvement. A couple of weeks ago i ran a tank of V power which did show some improvement but still not great (although it did run smoother and 'peppier'). i am going to run a single shot Millers Injector cleaner through with the next tankful.
I want to look at this sooner than later so I can get a more accurate idea of the 5th gear upgrade, new tyres and 'aero' tweaks i am having carried out over the next week or so.
