Getting an average of about 37-38mpg for my TD4 manual beast, mostly on decent A roads/dual carriageway but with some town driving thrown in, and more than happy with that.

Full tank gives me an estimated 550+ miles, but i'm not going to push my luck by taking the gauge too low.

I don't normally bother with this thread but... I just had my best L/100 (MPG) going in my I6!

9.6l/100kms (29MPG) and a range of 655kms (406 miles). Using Shell V-Power 98.

40kms still showing on the computer but don't trust it that much.

All mainly 100/110kph on cruise and with the A/C on - so could do better!

Probably sounds crap to the Diesels, but I'm well happy with that.

Run from Dorset to Canterbury and back plus some local travel around town, otherwise mainly motorway/main roads, average over 550 miles is 44mpg. Can't complain.

230mile round trip 34.5mpg
running total at 7800 miles 27.5mpg trip b trip computer.

I went from Kent to Windsor and back av 31 mpg
I have just cleaned the map spencer and the other senser by the air box,with carb clean
I'am going back to Windsor tomorrow hope to get a little more 😇mpg

Which two sensors are you talking about? Would be interested to hear about any improvements.

I will post my findings
If there is a improvement I will photo the censer locations for you 😜

Just filled up using Tescos diesel mpg seems to be a little lower and the car feels rougher

99.9p a litre might have been a mistake, back to Shell Nitro I think Former Mod/Member, with the most post & Chicken George Arch nemesis

Wow that's cheap, I just paid £1.12 tesco
Thinking off trying she'll next

Just got back this time I slowed from 70mph. To 60mph £40mpg
Was it me driving slower or cleaning the sensors

Only went as I had 12p off voucher, normally let the wife use them but her car is full still since the last time she used the vouchers Former Mod/Member, with the most post & Chicken George Arch nemesis

I called at a BP station last week, they had tear off vouchers for 5p litre off if you purchased two Mcvitiies share tube biscuit things, they held about 15 biscuits (as a guess) and cost a whopping £2.59 each ... WTF

The wife and I had a "wee" day out. Went from Hamilton to Fort William , if anyone doesn't know the route , you go by Loch Lomond , up the A82 .
250 mile round trip and got 40mpg didn't use cruise once Do it now ! Your a long time dead !!

Somerset to Ironbridge and home again
37.3Mpg Average

900 mile round trip Birmingham to northern france, 38mpg ave, cruise on the speed limit most of the time 70 / 110/130 kph...mind you that is super diesel in France for the same as UK price, apart from Calais where it was more expensive than UK! 2000 Xei 1.8 gone
2004 HSE Td4 Auto, MT's, sump guard, sliderz - gone

i am quietly impressed with the SD4 engine when compared to my old TD4

My trip down from Leeds to Burton On Trent was 38.7mpg, which a lot of 50mph roadworks

My trip back up yesterday from B on T again slow going 50mph to 75 ish and returned 42mpg, with 3 adults a child and a dog in the car
