Giday guys
I'm booking my patrol into Turbo Engineering in Thomastown soon to have it tuned.
I've been keeping track of fuel use since I got it a few months ago, not real happy with it.
Anyone had work done from there that can share the experience?
After I have had the work done ill post up the results of fuel use a few weeks later to compare.
Ill try to add a printout of the PDF file with fuel use figures.
Ignore the first 3 entries not sure what went wrong there.
Cheers Ill
i have the same vehicle it does about 6 klm per litre,my previous two patrols were 3litre manuals not crd and did 8.5klm per litre , havent been able to improve its thirst,what are your figures.
Whats that in ltrs /kilometers, also what size tyres
you'll get great fuel figures with 265s [32] OE tyres
changes when running 285s.
Not sure why the CRD's have such wide variance in their fuel economy. For some reason you can have 2 stock cars straight from the factory floor and one will use 11l/100 and the other 19l/100. Go figure.
There are lots of other factors like accessories, tyres, weight, temperature, etc that will contribute to usage
Lots of people have tried number of things to rectify the issue but the only one I heard fixing the issue was replacement of pump/injectors and the rail. Nissan of course will say its normal and wipe their hands of it.
The guys that persist and fight on get some resolution to the problem
Those figures are about what I'm getting also, on stock Tyres 15-16per100 ,16-17per100 with 33's .will be interested to see the change you get after tune but will depend what other mods are on your rig, I know mine is on the heavier end of the scale
Would be around 16.6 per 100Quote:

I think mine is just a fraction better than yours mate, about 6.5Klm per litre.Quote:

That is with front and rear bar, winch, drawers, lift, underbody protection, 33's, etc
Used to be 10.5l/100 stock.
..........on the move
Mate its about 6.5Klms to the litre I think, I'm running 265/70/17s BFG'sQuote:

I think they will suggest a chip and exhaust to start of with, then unfortunately its changing expensive bitsQuote:

Usually Chips use more fuel not less. Their whole function in life is to get more fuel into the cylinder by either raising injection pressure or holding the injector open for longer.
Human nature is such that 99% of us use the 'extra' performance for exactly that, more grunt rather than lifting the foot and conserving gas.
Mate since I'm no mechanic and definitely no expert i wont argue with you on that point, but i do have a few mates that have had things done by the same workshop who say they have more power when needed and use less fuel for the same driving, but ill let you know when i get it done if they were hyping it up, i have the fuel figures for the last 4 or 5 months so it shouldn't take too many tanks for me to get a good idea of the difference.Quote:

Same here ronin, 2012 gu8 st auto with factory bullbar and towbar. After 15,000km average consumption is 13.9 LHK ranging from 15.3 to 12.9 LHK.
mine 07 crd 16l/100 just driving around town filled yesterday and turned the snorkel sideways and ill see how that goes as i have read thr ram air effect can increase fuel use
Pretty high numbers for a small engine!
2007 CRD Auto. Just did a trip to Albany from Perth (400KM) last weekend. Running 235/85/R16 cooper ST, empty roof rack and minimal gear in car. driving down used 16.00L/100km sitting on 110 and slowing on hills. did 484km driving the sights around albany and used 16.14L/100km. flogged her on the way back to perth holding 110kmh up hills and used 13.8L/100km go figure.
Hi. Just come back from a Queensland trip via Sydney both up and back. A mix of highway cursing at 110km to stuck in traffic. 4483.8 Kilometres used 682.97 litres, mileage was 15.23 l/100k ( 6.56km/l). Vehicle is a GU7 3.0CRD. full loaded with 2 adults, 3 kids, roof rack and luggage.
Ok didn't quite work out they way I planned, gonna have to put the chip and exhaust off for a little while, ran out of funds.
Here is a copy of the work done to the car, $2700 later.
Doesn't seem to have made any real difference, and looking at the dyno report shows more torque before the work than after, not real good at understanding the dyno printout.

The Dyno runs before and after work done.

The fuel figures, Green Before, Yellow After, cant see any difference.

Well i had budgeted for about $4500 with chip and exhaust and service, but it would have come to well over $7000 with what was also done to the car so had to put a hold on things.
Maybe I'm a bit naive thinking $4500 was going cover it.
Got quoted between $1200-$1500 for the manifold leak on its own.
The manifold leak ill have to fix myself, seems the manifold is warped on number 1.
And ill most likely buy a Redback 3inch exhaust and also fit that myself to save some $$$
Ill add to this as I go, but sorry guys nothing really useful to add to this thread at this time.
Cheers Illya
