Thread: I know they are thirsty BUT GEEZ

Have you checked for fuel leaks .....24L per 100kms there's definitely something wrong.

No leaks around fuel rail....Maybe check for split in fuel tank (they are plastic) or from the main rear fuel filter located on the chassis ....any place along the fuel line that has a join.

My 92 classic would have similar fuel consumption to my old 96 Disco ....15L per 100 Klms ....

Most post on fuel consumption relates to new owners understanding that pushing a vehicle weighing over two tonnes and as aerodynamic as a brick was never going to be good ....But your is just bad

Interested to see what others have to say .... Hope you get it sorted soon.


Baggy

All I can offer is empathy. I've got similar figures (25l/100) on my 92 RRC, and it appears as though everything seems to be running just fine.

I don't know how to check for fuel leaks, so I guess I'm going to probably need to strap a camera on the underside to see if there's any fuel leaking out through the the fuel lines.

G`day ,

checking mechanical condition should be your starting point , it is often forgotten about underestimated or overlooked don`t know the reason but often no mentioned of it on this site . Tends to be buy this or that , replace this or that .

If the compression is low the cam is worn the timing chain is stretched ETC won`t matter how the sensors , ignition , fuel ETC is the economy will be bad .

Basic tests using a Compression Gauge and Vacuum Gauge would be a pretty simple place to start .

If you not familiar with them Google how to use and how they work and also " " economy and mechanical condition "

Cheers

If your temp sensor for the ECU (not the gauge) is stuffed and reading low, you won't get a fault code, just heaps more fuel being poured into the engine. Worth checking each sensor to see if it is functioning properly.

PLR's comments are also very pertinent.

My 74 2 door gets a little less than that sort of consumption, albeit with a 350 that's done close to 700,000 and the consumption is LPG.

You'll figure it out with all the erudite assistance on this site.

The Big Clue is the smell of unburnt petrol.

First impression is your cold start protocol is 'ON' - the fuel injection ECU is getting the wrong advice from temperature sensors (already mentioned by Homestar,and totally worth a look)

Changed the air filter ?

All your spark plugs hot and happy ?

Rest of your Ignition system up to scratch? Got a maximum Static Advance (around 12 degrees, not '6' )

Possible, - but less likely.... fuel pressure regulator is letting through way too much.

Now for the Techy Stuff, this is great background / educational info.
Owning a Land Rover means you need to know heaps of mechanical / electrical stuff, even if you don't personally swing the Sidchromes. The ability to make Intelligent fault-descriptions to your LR Technician will save you time & money. And frustration

EDIT: around 20 to 21 litres/100km, or when I last did the math, $26 to $30 per 100km Depending on co$t of fuel...

Thanks Guys, All good advice.


My first thought was it was staying on cold start enrichment. The RoverGauge indicates the temp sensor is reading normal but I'll get the multimeter out and check the resistance.


I'll also get the compression and vacuum gauges out on the weekend and see what kind of condition my 270K engine is.


I'm also doing all my bushes, rear ball joint and working out why one of my A/C condenser fans isn't working.


So a few days of beers and playing with the Rangie. Can't think of a better way to spend the weekend .


I'll get back to you all with result.
