MPG Dropped Dramatically

[godsANGER]

Oks since i did my service on the old girl my MPG seams to have dropped a lot, the clocks MPG says i am getting mid 40's on the way to work and back when before i was getting low to mid 30's but having to fuel up more. for example i put £20 in a week which used to get me to work and back all week and to the gym now i am putting it between £30-35. other day £20 lasted me 99miles before light poped up.

This is becoming a pain in the arse as i am driving more Eco but not getting any gain from it, the cost is getting outa hand as i get pained feck all for what i do. so need it sorting.

i have scanned it with a bluetooth OBD2 conector and the torque app scans come out clean, theres is no smell of fuel in engine bay, around the car or when driving. the car seams to be driving the same no more no less power.

 

Any ideas what can be as i would be grateful for any help.

Thats what you call TAX on fuel mate the prices have rencently gone up, have you factored for this?

is it pulling ok etc? lumpy idle? Prob just because the cold. 40's mpg to 30's aint dramatic if it was strugling to hit 20mpg then you know something is up

lol TAX more like theft, yer have  stil dosnt add up

seams to be driving the same, idles always been a little iffy, but since service it sames a lot better.
its gone from 30's to 40mpg so the trip computer thinks i am doing more MPG but the fact i have to fill up more says thats wrong lol

dont measure by £££'s measure by litres, i fill up exactly 26ltrs every week as that is exactly what i use and exactly before the pump tells me its filled me up, i know this because its clicks about .54ltrs after 26ltres is delivered.

26ltrs around here was £35-37, now its about £40

Well 14 ltrs (remembered how much i put in last) lasted me 99miles at a average MPG for 41* according to the Trip computer.

to me that dosnt sound right, may be wrong.
