Hello, I’ve recently noticed a large drop in mpg on my 16 plate gtd. normally on my way to work I’ll get between 43 to 46 through town on a quite morning. This never differs and it’s been like that since I purchased the car . I now get low 30s trying my hardest to cost up to traffic lights and keep rolling. Same on steady motorway trips as well, where before I’d get low to mid 50s I’m now in low 40s. I’ve noticed no difference in power , car feels the same, tyre pressures good .
Has any body experienced this or any ideas, thanks
