Thread: Petrol v diesel economy

Back in the day, possibly incorrectly, I worked out that if the fuel mileage was the same then it took quite a few thousand ks before the diesel started to beat the petrol
Considering 2000-2010 model 4wds, (the models I am likely to afford one day), are they comparable or are the petrol models just to poor?
Some of their prices are good but there may be a good reason for that.
I do know my 3.2 by bighorn liked a drink but by the same token my current 2.8 lwb pajero is nudging 22mpg which isnt that great

My calculations are the same as yours. When you take into account the 'total cost of ownership', there are no savings in diesel, and a whole lot of potential costs if things go wrong (fuel pump + injectors).

With the modern common rail diesels, buy new and sell before the warrantee runs out.
If you want to buy second hand, buy petrol.
Wont be selling my 4.0 V6 Hilux any time soon.

diesel = more torque
apart from that its pretty much $ for $ nowadays

Their is only 20-30 cents odd difference between diesel and 91 around here,
then there is road tax and dearer registration so.....

Crate V8 in the Colorado, Yeah , yeah. yeah.

That'll change quite soon when our Comrade leader takes the tax reduction back on petrol, gonna be some knashing of the teeth when that happens!

Seen some of the V6 4 litre (VE) I think nissan pathfinders.
That's meant to be a good engine too.

I have been researching into changing to a 4dr wrangler, with the v6 petrol..
but...
again
Wherever you look there is good and bad, also they don't seem to be very prevalent on here and you would think if they are a good machine a number of blokes would have them.
Would only be looking at 40-50thou so 2014 to 20??
They are rather expensive.

Probably because diesel is so entrenched in our 4wd history and logic. Plus I can albut gaurantee that some of the patrols are way worse than they should be scaring them off.
Also suggest if the road tax was on the bowser, not on a separate ticket people might get it.
In aussie I think diesel is either real close to petrol or dearer.
Unless you really need it for water crossings etc, petrol isnt so bad

problem is how many different levels of road users there are wouldn't work for trucks and such which pay 20-40c a km depending on how many axels/ weight etc

Yes, Diesel is more expensive in AUS than 98, slightly.
Always used this app or website when it came time to fill up, would be good if we had one similar in NZ. Gives you the price of different fuels on a map.

I know a lot of farmers (I know) like diesel, as they can run their vehicles off their tractor fuel supply (negating some road tax in fuel prices ~ 20C/L) but "only for farm use" and "require" pump gas for road use

The workshop that services my ute told me a couple of his clients got caught out claiming gst on diesel while tampering with their speedo and got stung for the rucs they hadn't paid.

Modern utes go into limp mode if you even look funny at the odo - I haven't heard of a way around that one yet. I had a safari odo that was probably wound on the way in off the boat - I got it off a farm needing rust repairs and cheap as chips so I wasn't too worried at the time but the interesting thing was it developed a fault that the 10,000km number would wind over then click back to the previous. I was just careful to make sure the thing was a few k up each WOF and no one asked. Yeah it's only a toy har har doesn't do many K's... The next guy who brought it off me got pinged a couple of years after I sold it and they got a lot more strict on diesel odo's, he reckoned it was bloody painful. They made him repair it and get it certified, there was only two outfits doing it in NZ at the time (one in each island) and it was a month turnaround and it made his wallet pocket scream.

I can not confirm or deny that a waikato mechanic, a for a bottle of spirits per wof used to knock the k's back on nissans,
allegedly had the drill adaptor for the speedos, was only meant to be used to bring new speedos up to the current km with out re-certing.
who knows tho, battery drills are so hard to get right these days, forward reverse or neutral.

Type speedo correction into facebook market place and there are plenty of people who will make your ute speedo read what ever you want. Cant do a hilux or a navara most of them say.
