Thread: D2 TD5 Fuel Economy Estimate for Canning Stock Route

I have a few mods, but overall normally get about average TD5 fuel use in any given scenario, plus I prefer to be a bit of a nanna driver to preserve the daily driver wee beastie. Around town long term average of 12 - 12.5 L/100 km, highway at 100kpm about 10.75 and at 110 about 12.

I've done it twice a long, long time ago. Once in a 70's RR Classic and once in a Series III SWB Diesel. Both times it came out to be around 2 to 3 times the around town average. In both cases the cars were properly full of "stuff" with two people.

Hi Gavin

To give you some idea I averaged 14.5l/100km on the Holland track last year. My worst consumption figure in 5 years of ownership was 16.5l/100km pulling my van.

My experience with diesels is that in slow going the percentage increase in fuel consumption is a lot less than petrol engines. I reckon using 16-17l/100km for planning purposes would should give you a nice safety margin.

One thing to keep in mind is the load you're carrying. I did a load calc on Charlie last night, for the Central Aust trip, and with fitted accessories, spares, gear and 2 bodies we'll be about 20-40kg under max payload.

Cheers

Steve

Cheers, yes the Holland was a bit easier on fuel than I would expect of the CSR.
Even towing my brick (albeit at 80 kmph) my worst was 18L/100km, so I concur with your figures. My post did not include a safety factor, which I would have added in at the end with additional fuel.
Enjoy the centre.

Mid 15s is what I get running around Moreton/Fraser with the TD5 and mine is v heavy. Worst was just shy 17 when I had to "commute" to/from the barge on Moreton during high tide scenarios .. so pushing soft sand most of the time.

We will be 2 people, rear seat removed, but still fully loaded and unfortunately requiring my heavy half roof rack to carry the RV4 - some things are not negotiable for SWAMBO to come, and yes I do want her to enjoy the experience (in August).

Never done it, so no idea, but I'm curious: "highway at 100" you get 10.75? Is that with or without the roof rack? Mine ( ARB winch bar, no rack ) easily got 10.00 with four adults, their luggage ( not camping gear ) and a 60kg dog. It does have a mild chip, however. You beat me 'round town though, where I have a tendency to use the chip. Mine's an auto.

Mine is an auto too with mild chip, 265 75 oversize tyres, Allard intercooler and the usual decat and de-erg. Have only done the one 500k round trip at 100 (by myself, but a part load). No roof rack, but have double length LR rails with 5 cross bars. Have never touched the boost (but am about to experiment). Looks like we are in the same ballpark, but I'd better use at least 17 to give me a little leeway in addition to a few extra litres.

Tyres are bigger. I have those on the D1, my D2 has 245s. Still has a cat, but de ERG. Boost std. Of course, my figures are simple. The difference could be as simple as different sensitivity on the auto cut off on the bowser. I never really bothered to keep a long term record.
