Looking for a 4wd to travel around & tow 14 ft caravan will be second hand
Narrowed down to a toyota prado good write ups & fuel consumption.
I know they say diesel is better for towing etc in long run.
But the figures for 4L v6 prado stack up pretty good against the 3L prado diesel
Not much difference in fuel usage.
Diesel service every 5000 km
Petrol ,, ,, 10000 km
176kw 376nm petrol
96kw. 343nm diesel

What do you think?

Prado diesel is about the poorest 4WD diesel on the market, but the petrol is great.

Prados are a great vehicle, the large fuel tank can be really handy.
If you really want to see the advantages of diesel over petrol, look at a Land Rover Disco 3/4, Jeep or Pajero, where the diesels have 25-30% better fuel economy.
Pajero service interval is 15000km for either Petrol or diesel.
Also depends were you do most of your kms, if in the city diesel is a lot more expensive (due to petrol discounting), but in the bush there isn't much difference between the two fuels.

Will be on the road permanently, find a good place stay a while then move on. Another thing I looked at was price of acessories, bull bar etc
Had a 100 series LC b4 but being a 4.5 petrol very thirsty but a great truck.

and sooo CHEAP compared to the TD.. nearly half the price.
be maaaaad to go the TD when the v8 is soo cheap !!

Here we go this is going to end up like a tyre thread but for me for long ranger travellling and towing a diesel blows the petrol away for reliability, econonomy and fuel dollars.
Really depends on what you are doing with your 4wd. If its off road, isolatation, the odd water crossings again why would you go Petrol???

Personally I would never buy another petrol car. But if you are looking at earlier model Jap cars then their diesels were the pits. Low power and torque, poor fuel economy and a short service cycle. Doesn't sound very inviting to me.

Hi Michael.From what I've read on forums the V6 petrol uses around 16 litres per 100kms not towing general day to day use. Diesel uses around 12 litres per 100kms. My choice is a dual fuel cruiser. average cents per km running gas and a bit of petrol is cheaper than diesel. I know when we head outback gas is not available, however overall in the life of owning the vehicle I think it's the cheaper way to go. Sure the cruiser can be thirsty, but I've read V6 cruisers towing use the same as a 4.5 litre engine... Happy travels.

Hi Bob if your referring to the 1KZ diesel mine use to use 13/14 around town, freeway it would crack the tens if you sat on 90, sit on 110 and it climbed to mid 11's to 12's and if it was a hot bleep ty steamy day running aircon and trying to maintain 110 it would jump to 15. Not a very economical diesel engine. Better in manual mode, mine was auto.............

Had three prados all up (currently have 05 GXL auto V6) 2, 90 series one petrol one diesel, both auto's both grande's running the same gear (arb winch bar, bigger wheels, lift etc) The V6 I have now would have to be one of the best 4wd's I've owned. (have had hilux, vitara's etc) The 4L V6 is very reliable, not that bad on fuel considering the weight and size. I average 11.4L/11.6L per 100 on the open road cruising loaded with air on and off and 3 on board. Around town about 15/16L per 100 and I don't baby it. The 1kz in the 90 and 120 in my opinion is a dog of an engine and I would never have another one. If finances can stretch it a D4D would be the way to go although they have some issues as well (I wouldn't have one) Toyota need to lift their game they are way behind compared to say mazda, ford ranger etc. I get better economy out of my 120 V6 then I ever did out of the previous two prados (not including cracked heads on the 90 1KZ's which is common including the hilux's) You can flick over to pradopoint.com and check out some fair dinkum fuel figures from any model prado. The 1kz is definitely better in manual for but if towing don't expect the 1kz to be better then a 4L V6, you will be disappointed. I use to get 12.2 towing my camper behind my 90 V6 3.4L and 17.2L per 100 round town. Water is hardly an issue these days with petrol, no distributor, etc the current V6 hving their own coil packs etc Ive had water up nudging the bonnet of my 90 never had an issue, even at that height I would run a blind anyway with a diesel. Drive both and go from there. Ive had nearly two t behind my current 120 only a few weeks ago and yes of course it new it was there but plenty of grunt. I didn't take into account fuel usage so cant comment but the guage didn't plummet like some petrols do. If I was touring/retired I would personally buy a pajero with the 3.2 DiD ripped of an engine and great economy even when towing but for the amount of times I two (maximum 4 weeks of the year) I love the petrol and suits me fine.......just my opinion........

Because I have one leg only car will hav to be auto have read the prado site liked what they said about v6 4L so am leaning towards that way at the moment. As well the acessories like bullbars etc are quite cheap compared to other makes.
What we would like to do is to be able is to purchase vehicle and add
Roof rack
Suspension kit
Side rail/ steps
Rear bar
Which looking at prices should be able to do for around $30000 including car.
If I could get a diesel pajero with low enough k,s would look at that vehicle

Just wondering what size tyres you ran on the prado when you refer to bigger wheels?

On the 90's I ran 75 profile instead of the factory 70profile. If I had kept the factory profile my economy would have been better. Running higher profile does zap some power and increases fuel usage. With the 120 I have stuck to the factory 65 profile as it also affects the low range gearing ...

I'd go turbo diesel for fuel economy unless money isn't an issue and you like spending time at the fuel bowser then go petrol and then after a while you'll probably start driving at 85kph because your shocked by how much petrol it drinks . See how the fuel figures stack up once you start towing espically when you get into some hilly country.

With the D4D they tested a petrol V6 Hilux vs the diesel, took both cars around Australia, they towed, did 4WD'ing etc etc, when it was all said and done the Diesel used around half the fuel of the petrol. By the way I was of the understanding you could run 10,000 service interals on the Prado Diesel?

In regards to services with the 1kz 5000k services are still recomended. We're they testing the 1kz or the D4D ?? I would not believe the petrol used double over the 1kz engine, D4D which our friends have and have just completed a lap in there dual cab lux towing 16 1/2 footer loaded averaged 15 per 100 pretty sure a 120 petrol would not use 30 ?? May climb into low 20's especially if head winds etc or trying to punch 110 up every hill, and you will pay 10 k more for a D4D that will buy a lot of extra's and fuel.. I certainly would buy diesel if I was retired and towing doing a lot of towing and touring but as I only tow a few times a year and like the get up and go for every day driving etc I'm happy with my choice. As mentioned above I would buy a pajero before I would buy a Prado for every day touring/ towing, heaps more grunt and more economical........
