Hi All, we are towing a jayco expanda (about 2600-2800kg I beleive) with a 2006 toyota landcruiser 100 series diiesel around australia. My fuel usage is about 19-22lt/100k. On the highway I try to stay around 90km/hr and less than 2500rpm. Can anyone advise...I thought my fuel economy would be better...does this sound about right? Is there a sweet spot for speed and rpm to give best fuel economy or shoudl I not worry about it too much? Thanks for any advice!

Mark that seems very high.
AFIK a factory turbo 100 should do in the 10-12 mark for high way cruising.
I have a 105 (1hz with after market turbo) which will do 13-14.

Nomad they are towing figures and are close to the mark.
I was getting, on my 96 80 series 1HD FT turbo, 17.5 towing 2.2 tonnes before rebuild not sure what I am getting now. Waiting for engine to settle in before doing figures again.
Cheers, Bruce.

Firstly is it a 1HD-FTE turbo or a dead slow 1HZ
My TD does 17.5l per 100km towing over 2.5t at 90kph in 4th gear
2300 rpm is the sweetspot in a 5spd auto.
I NEVER tow in 5th.
It does 10.5l per 100k at speed limit running solo and medium loaded.
Must be a b+++dy big Expnda to be 2800kg as a Sterling 24ft wouldnt be that heavy.
What does the ATM figure on the Compliance plate say.

I've only had my combination for 5 weeks but around town with an '03 TD 100 series I've been using 13.33 lts per 100ks. Not really ideal what we're using it for, trips to shops, school pick up and drop off so I'm guessing that's why it's a bit high.
I gave it a run last weekend with the van on the back (2.8t loaded). Only did 600kms but it used 15.8 per 100ks.
I was pleasantly surprised. I'll see how I go in 3 1/2 weeks when we take off on the big trip. Might get a reality
check when we hit some steeper terrain and wind.
I didn't use the gears, I just towed in drive and cruised between 85-95kph most of the time.

You will regret towing in drive as the car runs hotter than in 4th.
It also lugs as it is not up in the sweet spot which is 2300rpm.
You will find it hunts up and down all the time.
OD or 5th is meant as a cruising gear for the vehicle ON ITS OWN not when double the weight
After a trip around the country, believe me its better and doesnt impact on fuel consumption and at over $5000 to recon an auto I would never tow in OD.

In fact on page 229 of your manual it states not to tow in 5th or O/D.

Anything around 20l/100km is ok - our F250 D/cab towing 3480kg boat with
the tub full as
well managed 30-36l/100km. Unfortunately the lease expired and was replaced by 200 LC 2 hairdryer diesel. Now we get around 30-35l/100km but can't carry the same stuff in the vehicle so need another LC to come as
well - talk about backwards. Sweet spot - generally where the NMs and KWs sort of meet is the place to aim for - but within a couple of hundred revs is ok. rgds

Figures are not fanciful at all.
Mine are consistent with other users and have been carefully checked.
Recently did two return trips from mid north coast to QLD and got 10.4l per 100k at speed limit.
Had about 150k of gear plus us in it.
Was getting 17.5l per 100k over an extended trip of more than a year towing just under 3000kg.
Plenty of others get similar figures.

Yes this one of those replys brothers.uncles,aunts BUT I know for sure (been away with them) that my uncle gets low to mid 10's freeway driving (not towing very little load but always has the aircon on), around town on average hes getting 14's start stop, shops etc, towing around high 17's but I dont know how heavy his van is but I know its 24 foot long, shower,
toilet aircon, etc all the mod cons Just updated again last year. He had an 80 series petrol before that and was always between 25/30L per 100 towing, 22/23 round town, loved the 80 but fuel was killing him so went the factory turbo diesel 100 series 5 speed auto 07 model, (I think for memory the very last of them) They travel for 6 months of the year every year, lucky buggars.
