1) Check for oil in the IC.
2) Run 500ml of good non-synth two-stroke thru a full tank of diesel to clean up the injector tips and combustion chambers
3) Have the turbo boost checked: if the turbo is not healthy, your consumption starts to suffer
4) Check your oil for diesel residue: could be injector seals

a) it isn't needed, OE filters in a Defender flow more than enough air in a stock engine, or a Donaldson or Fleetguard filter is a better bet and it will fit in the stock housing (less restrictive again and more paper area)
b) a K&N lets far too much through, the small stuff that wears bores ;)
I'll dig up the K&N filter tests we've done on here or just PM isuzurover and ask what he thinks of K&N's.

I've run an ashless full syn two stroke as a pump lube, but I doubt it would move too much from the tips and chambers in one tank, even though JASO FD oils have pretty good detegency (and i don't think any mineral based oils can meet JASO FD ??)Quote:

I know that Redlines additives don't show on used oil analysis, unlike some.
A 300Tdi doesn't have the O ring problem of a TD5 either, mechanical injection, copper washers under the injectors ;)
BP have refineries in Brisbane and Perth and refine diesel at both (and that's why BP Ultimate diesel is available in those two states)Quote:

Caltex has a refinery in Brisbane that produces ULS diesel too.
Can't remember if there's a refinery in SA/Adelaide ?
[edit] Port Stanvac refinery in Adelaide was mothballed by Mobil a while back apparently and is being demolished.
James, as the other fella's have suggested try some different fuel and definitely adjust the rockers, JC swears it makes a big improvement on the cars he services.
I've had economy variations just from the difference between summer and winter fuels here.
I haven't been away on a long distance trip for two years (:mad:) so I'd say Ive only done around 15000kms since the guy who serviced it reported the gaps were out and had adjusted them.Quote:

I'll also replace the fuel filter and after I do that I'll sell a kidney and try some BP super diesel.
Will report back in a month or two.
Thanks for all the great ideas everyone.
My 1997 Tdi has done 214000km I run 32" Muddies, with a bull bar and long range tank (heavy). I average 10L/100km. It doesn't get worse than 12.5l/100km on stockton beach. I'd be upset and worried with an average of 14l/100km - seriously.Quote:

I have to do this on my td5 as economy has gone to peices.. changed the intercooler hoses at the weekend and was amazed how much oil was in there and the other side..Quote:

I'd be checking this just to be sure also...
As for BP ultimate... i lost a 100k's on the disco td5 the one time i tried it.. we generally use peak in both.. as we get the discount and the servo we use is the cheapest around (even over other peak servos)

Some Disco's (hardly any made it to Australia ?) have an electronically controlled boost compensator instead of the mechanical one, with #1 injector having a sensor on it.Quote:

My 'fender with the fuel turned up, 33" MT's, ladders on top, bull bar, winch, sidesteps and brush bars, etc, etc. tares out at around 2660kg with the gear I have in it all the time and mostly uses somewhere between 11.5 and 12.5l/100km whenever I've bothered checking (not often)
Defenders push a lot more air than a Disco too.
More than demoilished... Its becoming a De-Sal plant :eek:Quote:
