Hi. ive been getting poor fuel consumption lately. the wife only does vicarage mileage per week so it doesn't get many nice runs. it takes a long while for the mpg to give a figure when reset but on a fair steady run im getting 22 to 29 mpg. but takes a long while to get the high numbers. are their any known faults that can cause it ? its had new injectors, recent oil change and passed its mot ok back in march 14.
I have just done York and back 190 miles and I have averaged 28.4 Sat at 90 the whole journey. But back and forwards to work 12 miles of stop start ish I average 21!
I have averaged 30 bang on over the last 2,500 miles in my remapped R26, most of which is driving to work and back. My old 5dr 225 (standard) used to do 27.4 on the same journeys.
If you have a Megane RS! and your getting more than 30mpg theres something wrong. #DriveItLikeYouStoleIt
i travel 3 miles to work and do a couple of motorway journeys i never reset the trip though and dont get more than 24 mpg, same in my last 3 door meg.
My trip always under-reads, it's never once been over. Just goes to show it's not too reliable a method.
