The Diesel Economy: I just don't get it.

The extra $10k you gain in resale outweighs any downsides to injectors. Most will pass the car on buy then anyway.

Leave out info like what? Engines shouldn't blow up - period!

Yes you are possibly over stressing about diesel engine rebuild, unlikely under 400 000 but it can happen with any engine. D4D Prado and Pajero will need injector changes as they are disposable. The Disco 3 should be good for injectors but small fuel tank and a host of other potential problems. Nothing too wrong with petrol prado just economy, towing and torque to consider.

Leave out info like what? Engines shouldn't blow up - period!

Like the fact that they had a chip fitted, but will swear black and blue they never did, despite that being the very first thing they removed from the vehicle before it got towed!

Or the fact that they new they had an issue and decided to drive the vehicle anyway.

Engines go bang, they always have and they always will. Engines modified for more power (chip) are more susceptible to going bang. Engines that don't receive the appropriate maintenance when a problem is noticed are more likely to go bang.

Clearly this is not always the case, but I know of a couple on this forum that those circumstances apply to, and I know that for an absolute undeniable undisputable fact!

Thanks guys, you are all assuaging my diesel fears. You hear all the horror stories and think "what if that happened to me?". From the comments from petrol guys here is seems like I can't really go wrong either way, just have to be aware of the higher fuel use in the petrol. I'd be using it as a daily driver for most of the week (probably 70% highway), and hopefully camping at least once a month with 1 or 2 big trips a year.

Does the resale difference close as the vehicles age? Seems like a lot of 90 series petrol and diesels are selling for around the same price nowadays.

Have a good look around on this forum and compare the amount of posts about problems with diesels vs problems with petrols . Then have a look at the amount of posts about diesel owners wanting to get more power out of their snail and the costs associated with that . There is no saving on the diesel . If you drove your diesel from Melbourne to Cape York and back , you will need to service it on the way there and on the way back . Now that's really saving time and money (sarcasm )

Oh I just spotted another item you'll need to add to the cost of the diesel . The 120 000 k timing belt change . That's every 120 000 . That won't be cheap . Not needed on the petrol v6 .

IMHO I think there is a few reasons;

The fuel economy of the older 1KZ diesel was not as good as D4D and closer to the petrol version
&
The Power produced by the 1KZ diesel was not as good as D4D and resulted in a bigger performance penalty to the petrol version

so there was not as much of a benefit going diesel in a 90 series as there is in a post d4d 2006 car.

Another factor is that lets say there is a 15% diff in resale price, no matter what series prado, 15% of a 50k car is $7500 difference where as a 15% difference on a 15k car is only $2250.

Hence the closer gap on 90 series Playdos.

Have a good look around on this forum and compare the amount of posts about problems with diesels vs problems with petrols .

Simple volumes - The number of diesels sold far outweighs number of petrols. I read somewhere (can't find the link again) that over 70% of Prados sold are diesel. That's 140,000 new diesel prados vs 60,000 petrols sold upto 2013.

Then have a look at the amount of posts about diesel owners wanting to get more power out of their snail and the costs associated with that .

Don't know why - 420nm of Torque is more than enough for me...

There is no saving on the diesel . If you drove your diesel from Melbourne to Cape York and back , you will need to service it on the way there and on the way back . Now that's really saving time and money (sarcasm )

Rubbish - Melbourne to Cape York is 3,937km by most direct route, and the service intervals are 10,000km for both petrol and diesel. You'd have to service neither, because we'd all service our cars before the trip!

Fuel for trip to Cape York would cost you $831.87 petrol and $777.83 in diesel - That's an extra case of beer and bottle of wine saved right there. (more if you shop at Aldi)

(Average fuel price Nationwide 2014 - 148.8 Petrol/ 156.8 Diesel source AIP)
(Average fuel consumption Petrol 14.2/ Diesel 12.6 source Fuelly.com)

Now for time savings - well. with the petrol's 1300km range and the diesels 1700km range - you'd have to fill up 3 times in the petrol and only 2.3 times in the diesel. We all know how long it takes to fill them up from empty even at the high flow pumps. That's an extra 20 minutes saved right there.

I don't really have any preference between either, and I don't intend for this to be another diesel vs petrol thing; I'm just confused as to why diesel is always considered the cheaper option when repair bills appear to be so much higher.

Cheers.

In all seriousness, this is an interesting read: http://www.4x4australia.com.au/drive...diesel/image-2

Especially the verdict: "While there are plenty of hypotheticals in this study, it does blow away the myth that owning a diesel 4X4 is cheaper than owning a gas-guzzling petrol 4X4.

It also shows that it pays to do a lot of studying at home, calculator in hand, so you can make an informed purchase decision on your next new 4X4."

r4ndll some good pints there.
On the current fuel costs Caltex vortex Diesel is currently 10 - 12 cents / L cheaper than E10 where i fill up.
that = a few extra boxes of beer and a bottle of wine or 2 for the wife.
not sure how long it will stay this way.

[maulbeagle Senior Member Find all posts View Profile Close maulbeagle]

if you use E10 your fuel economy will be even worse and cost just as much if not more in the long run.

It's generally the first owner that takes the big devaluation hit, if your buying second hand it's less of a factor.

G'day Andrew and guys
Fellas tell me please... my D4D is absolutely in perfect nick for a nearly 200K motor - good torque/good fuel economy (10.6/100k)/no smoke black or white - on start up recently noticing a little rattle for a short while (just like me and winter). Spoke to Baileys who say Injector readings above +-1.8 should be replaced!!??
Had injectors removed and checked then replaced 30K back (because I asked for that to happen) - my reading just this week fgter a service before our trip was No.1 +2.1/No.2 -2.2/No.3+0.6/No.4--0.7.
Also spoke with Denso in Brissie and they say +/- 3.5 is time to take some action.
Would be pleased to hear some opinions based on experience, not rumours and innuendos.
Reason for question - Off to the Simpson Desert to the Big Red Bash, towing a campertrailer and... I am a sensible common sense 4x4 guy who absolutely looks after his truck but will play when its time to play.
So I suppose the question is:
Will I get the injectors replaced because they rattle a little bit for short time OR will I let it all go and get on with havin' fun with my truck?? and stop sweating about it??
regards

Also a Pro-ma guy wants me to put an oil additive in to "stop the rattle" any ideas??

YMUS - which injectors did you put in when you changed them out?
Did you also replace the SCV at the same time?

Suggest you grab a cold-start report including volume to have a better picture. Then also run and post the same numbers when warm.

I really appreciate all the information guys, thanks. There has been a pretty even response in favour of diesel and petrol; I think I might just find the best vehicle available regardless of motor!
