MPG-My TD4 Results.

One of the reasons I get higher fuel consumption is my love of the kick down, coupled with the Synergy's increased power it certainly helps with Motorway driving.

Hi Nick,

That just goes to show how different we all are - not right, not wrong - but different.

On motorways I have the Synergy set to 'Eco' for better fuel consumption on my long journeys.

I keep the power setting for the fun twisty bits on A & B roads and for my Alpine Pass adventures - a pastime to which I am addicted of course.

Hi Singvogel

Unfortunately I still drive diesels the way I learnt in the sixties, foot down to the floor as soon as you changed up to the next gear, that was in the days before commercials/psv's had turbo's and auto boxes with kick downs

Nick,

Back in the sixties I got a student summer job as a relief beer-delivery lorry driver.

That old Bedford had to be driven gently - an open flat-bad with a high tail-board. Loading it was like building the pyramids.

It were back in the days of wooden non-interlocking beer-crates. The company would only tolerate so much breakages.

How things have changed - the crates would get nicked off the back at the first traffic-lights these days - never mind the health and safety.

Back on thread - if your regularly using the kick-down you will use loads of extra fuel. My fuel meter shows that on hard acceleration it drops to 3 or 4 mpg - only for a 10 - 15 seconds or so for an overtake - but it must make a big difference.

S.

Bog standard 06 Td4 48K miles. I'm getting 36 - 38 around town / mixed driving and 42 - 44 on motorway runs.

Last tank was 515 miles on 55 litres (42.56 mpg). I'm pretty happy with that.

Hi guys,
My 2003 TD4 is running super sweet, no problems so i decided to do an mpg test over a few hundred miles.:
32.71111111 mpg
35.11450382 mpg
35.26666667 mpg
36.29241379 mpg

I have new DPH silicon turbo hoses, egr bypass, BMW cyclone breather, use 50ml of Millers per tank load, new tyres, new diff and vcu, new brake drums and brakes (not getting hot)....
Maybe I should have a lighter right foot....

My auto gives roughly the same. (8 decimal places !!!)

Hi my old 2001 manual TD4 with 140k has now achieved 42mpg!!! the worst is 38mpg
fitting a huge intercooler soon .... hoping for more improvement.

synergy on max
K&N
Decat
EGR removed
Restrictive elbow removed
New thermostat
2 Stroke oil in diesel
36 psi intyres

Whats the restricted elbow mate? I thought my psi was high at 31 but 36 the money you save on fuel you'll spend on tyres.

illy

shell/texaco .. regular diesel + 'diesel rhino' + 2-stroke oil
synergy on '10' ..
@ latest brim .. 44.5 mpg

definitely a brim-up as the pump didn't auto-stop ..
was watching the pump readout .. not paying attention ..
must have lost about a 1/4 litre in spill-over ..

( tyre psi .. 31
( egr deleted

~~~~~~~

had the tyres at a higher psi .. but felt the ride was a bit hard
and 'harder' on suspension components ..
although .. the steering wasn't as much effected by road surface contours ..
