I have a 2005 Prado Turbo Diesel Auto, done about 60K and am disappointed with fuel economy at 12.7lt per 100km without towing. ( Had a 2000 model and got 10lt/100km)
Do those fuel additives really work?
What economy is everyone else getting?

Avan,

I have a 2004 TD manual and get about 10.5 L/100 touring and when towing on a 12000K 3 month trip last year I averaged 15.22 L/100 with a 19' full size van behind.

Very happy with mine.

Cheers,

Cruiser

That's about the normal range for a 120 series prado auto. Expect around 14.7 or so fully loaded and off-road.

The 120 series is around 200 kgs heavier than the 90 series so is working slightly harder. Never saw 10l per 100 on our TDI 89 series auto it was around the 11's for normal running.

The weight would be based on a base car with no extras or accessories per the new vehice specs.

Your suggesting that extra weight contributes to the poorer economy. Well if that is right then explain how my 2002 95 series manual TD carrying around an extra 200+ kg all the time gets between 9.5 - 11L/100km.

Lets see now, extra weight from...

ARB steel roof rack
rear draws (with recovery gear and hand winch)
bull bar
second battery
towbar
cargo barrier

Lets not under state the extra wind resistence of the roof rack.

Can't agree with your thoery.

What is a TDI 89 series?

Wizard,
My last prado was also a 2002 GXLTD manual, and the only time I got the same economy as you was when the vehicle was new, on Grandtreks and little weight.

When I added everything else for a desert trip, it was up to 12.5 - 13.5 l/100k (speedo corrected with GPS).

There seems to be a lot of variation between Prados. I've done trips where one Prado TD got much better mileage than another - but I am at a loss to explain why.

Is that why they have a 180 litre tank standard.

LOL

Can we all speak in the same economy language of litres/100 km.

I've got the old motor & best I was able to do was 10.4l/100 on the freeway on my BFG MT's, 2 persons onboard & full tanks.

The thing with these cars is that they are significantly effected by head winds & hilly terrain. Any more than cruise throttle position & it starts to chew the juice.

You will also notice a big help if you slow even by 5km/h....& take it easier over the hills...

Generally on a trip with 2 adults & 4 kids and associated stuff, involving freeway, minor roads, dirt tracks & some 4wdriving I get around 13.5l/100km.

The secret is to get your cruise speed and hence revs just right for economy at highway speeds.

I regularily traverse the M1 motorway between the Gold Coast and Brisbane. It has strong cross winds most of the time. I can still get as low as 10L/100km on average with 11 being the highest, by just travelling no faster than 105 kph.

Around town you need to avoid high revs during change ups. Let the turbo do the work and change up sooner. They aren't designed to be race cars.

If you want to save fuel then let your ego go and slow down a bit and take your time.
