Hi All,
I am seriously considering changing my trustworthy V8 Disco for something with better economy but more importantly longer range. I have done a lot of research and most new-ish diesel autos fit the bill. On top of the list is the Prado mainly because of the standard 180 litre tank capacity. Then I read a post of a fuel comparison between a 3l diesel and 4l petrol Prado on a trip across the Simpson. The fuel consumption was almost exactly the same.
Now to my question.
If fuel consumption is taken out of the equation, what if any are the benefits of a diesel over a petrol engine? The only pros I can come up with are better availability of diesel in remote areas and possibly some advantage for wading through
water, but these may be offset by more frequent expensive servicing. Your input would be appreciated as now I am looking at both petrol and diesel Prados.
Thanks,
Doodle

So with a diesel you get better fuel economy, as a rule anyhow. Towing you would really notice the fuel economy thing.
The diesel in the Prado is a bit of a slug but if you wait a few months there will be a new hi tech common rail the same as the hilux.
Great economy, very clean engine. generally last longer than petrol engine.
Better engine braking maybe, depends on the gearbox a bit too, auto manual?
Not sure about the new Toyota but the new common rail Mitsubishi is only serviced every 15,000, 7500 if severe conditions.

Hi Notso,
Unfortunately my finances are limited to 2003 - 04 models, so waiting for a new model is not an option. I do think highly of the Pajero 3.2l diesel with the trip-tronic auto, but even with a long range tank it can't equal the Prado range.
Thanks for the reply.

We took one of each accross the
Canning Stock Route. petrol was available every where we went. We did however pass a freshly burnt 2 year-old petrol prado... spinefex apparently got caught around the catalic converter within ten minutes of an underbody
check... we heard it was too hot to be extinguished by fire exinguishers (I think they emptied a few!). We instantly became very nervous in the petrol prado, made it out fine though. for desert peace of mind we'd probably go for a desiel next time.

Yeah, but we've also seen pics posted here of a diesel variant doing exactly the same thing and burning to the ground.

Yep, a lot of the diesels have catalytic converters now so it's a problem with them too.

my understanding of the two is that the petrol engines run hotter than the desiel, I could be wrong, I believe the Turbo heats the desiel up any way...

Gday Doodle,
I have an 04 Gxl V6 Auto Prado and i drove both before i bought. I chose the petrol because the vehicles main purpose is highway use with the odd offroad trip each year. Being in
Cairns with all relatives down south, the vehicle does a lot of highway ks and is heads and shoulders above the diesel with overtaking ability. With this in mind and for my driving style the Diesel was not in the race.
If i was buying it to do a lot of serious off road work or a fair bit of towing i would have definately purchased the Diesel and installed a Dtronic. If i was looking at purchasing a new Prado now, i would buy the new model with the updated diesel regardless of its use. I have driven the current model hilux with this engine and was told by a Toyota service centre Manager that the new Prado engine will actually have more grunt than than the hilux because of a few mods. The difference between the current model diesel engine and the one coming out next month will be very very noticable. The fuel economy will also be better.
In my opinion (and thats all it is) when mated to automatic transmissions there is very little difference between the late model petrols and diesels offroad.
Cheers and Good Luck with the decision making.
Dave

Doodle,
Sorry mate i was writing my reply when you said you were looking secondhand.
Definately comes down to what you want to do with the vehicle and only you can make that decision. If not doing bleep loads of towing i believe the vehicles running costs are fairly similar.
Cheers
Dave

Hi Doodle,
If you've had a Disco, albeit a trustworthy V8, why change makes??
The Disco TD5 is seriously worth considering.
Cheers

Good question Disco Driver. I had the V8 Disco 1 for 8 years now and it hasn’t let me down. Mind you, I look after it mechanically. The only drawback is the 500km range and much less in heavy going. The TD5 is a brilliant motor and very economical and I haven't totally ruled it out, but I’m just thinking it’s time for a complete change. SWMBO and I love traveling in this vast country and will have time to do more. The biggest thing we tow is a CT which is less than a ton loaded, and only if we plan to stay in one spot for at least 5 or 6 days. Mostly we prefer a touring tent. We do get to some remote areas and I’m sick of having to take the trailer just for extra fuel.
I hadn’t even considered the Prado previously. In fact I never thought much of them until I started to research what would be the best vehicle for when I retire in a year or two at the most. The Prado came down to being one of the more reliable and economical vehicles for long term use. I originally did not even consider petrol until I found out the fuel consumption of the 2 Prados were basically the same. If the economics are similar, I’m thinking the petrol may be the better choice…….. or bite the bullet and wait for the new model!
I’ve driven many diesels but never owned one. Companies I worked for used diesels mainly for safety issues and because they had a lot of other equipment powered by diesel. Are there any other real advantages with the diesel?
Cheers,
Doodle

Thanks for all the replies.
My conclusion is, when it comes down to the current model Prado, I’d be better off with the 4l petrol engine - or wait for the new model for a diesel. Just about any other make of vehicle, the diesel would be first choice.
Thanks again,
Doodle

Doodle,
At the risk of starting a string of follow ups,(and for all you potential writers I'm not playing)I went through exactly the same thing last year, and finished up buying a 03 V6 petrol Prado. I wish I'd kept the figures, but when I calculated the difference in purchase price, servicing and fuel usage, I worked out I'd have to drive the vehicle something like 10 years at 15000km per year to make up the difference, if I bought a diesel. From memory the fuel usage is about 2litres per 100k more for the petrol. I am very happy with my purchase, and have used it off road a lot (incl. SW qld., and nthn SA towing a CT). The only thing that frustrates me is the idle speed - makes it difficult when going over rough terrain. There is certainly a higher risk with flammability of petrol.
Having the range is fantastic.
Good luck with your choice.
Craig.

Hi Doodle
I would be guided more by the condition and service history of the prado you intend buying. The deisel motor has an excellant record of reliabity. But toyota petrol motors often last as long as most diesel motors.If a turbo diesel goes bang you will wipe out 10 years of fuel savings.
good luck in your search
Pete

Main question is how are you going to use it.... The Petrol Prados are much
nicer to drive. Plus you can put a Petrol Prado on LPG, which will save you
on fuel bills around the town but makes remote trips a bit of the problem.
Running cost for diesel vs petrol will be the same - the cost of petrol will be
offset by the 5000km servicing of diesel....
