Im about to upgrade the company car, and with the price of petrol Im interested to understand the cost bennifit (if any) in having a diesel vehicle.

With Petrol you pay $1.76 a litre, Diesel is $1.20 ish ? but with diesel you have road user charges on top, taking those charges into account is it cheaper to have a diesel?

Being a company car some of you might say who gives a fuck, but the less impact to the company I can make reduces hassles I might get in relation to personal use, so its relevant to me.

The if Diesel, what to buy ? have to be a 4wd type thing or a comfy Double cab ute, I do big miles so comfort is important, speed, well dont care about that, handling I do though.

Appreciate your thoughts.

If you're buying a diesel get something fuel efficient.
Some of the big euro cars are now getting 50+mpg, so with road user charges on top works out about half the cost compared to a petrol car that averages 25-30mpg (like a big Holden V6 or something)
Big 4x4's etc are seldom fuel efficient when powered by deisel and you probably won't see any difference in running costs.
A mate has a Pajero and guzzles as much as a petrol car would, with road user charges on top it works out about the same.

My father went to welly the other day & back in his Jag V6 3.0L cost him $195 in petrol and averaged about 27mpg (10.5ish L/100km)
In a car such as a Citroen C5 Turbo diesel which manages 55mpg + road user charges of $34/1000km I think. He would have just about halved the cost to $100 or so.
Modern turbo diesels are just as fast as petrol motors, and last far longer......BMW and Merc sell more diesels in Europe than their petrol models.

Diesel 4WDs end up being about the same as their petrol counterparts, when TOC is taken into account. Have you thought about a Diesel Stationwagon as opposed to a utility vehicle? Much more comfortable, and the European Diesel's give nothing away to the equivalent petrol engined units in performance and tend to be much more fuel efficient in comparison.

Go diesel Quasi. I heard your Duc on the Naki run and it's obviously diesel too so you could use your company fuel card for this and save yourself some money.

Either that or one of those dashing hybrids.

I would agree with Simjen, I have run an Isuzu 4x4 for 7 years and its expensive in fuel and maintenance. Fuel economy is about 10 km per litre, oil & filter @ 5000 km, tyres $1200 @ 30000 km, lots of gearboxes to maintain!
Handling is ok in the isuzu but varies wildly across the different makes, you definately drive more slowly cause its a truck not a car!
The european new generation diesels are the way to go but you will need to decide on how much carrying / towing capacity you need.
My pick would be a mid sized (2 litre) car, economical to run, comfortable to travel in and capable of towing up to one tonne.

Let me know what you decide.

Hybrids are shit!
TopGear did a test as well as a few other mags on the Toyota Prius (shitbox) and found that it got nowhere near the Fuel Efficiency claims of the manufacturer.
A little diesel VW Polo was a better option in their opinion as it did a genuine 50+mpg with no effort.
Prius etc all have shitass low rolling resistance tires....much like the hardest possible cheap firestone retreads....so don't expect to go around corners!

Many moons ago the AA did a cost comparison and the big killer for the diesel was maintenance. Newer diesels may require less frequent and/or less expensive maintenance I don't know. But in their testing you had to run up about 100,000km before diesel became cheaper to operate.

As I say this was a long time ago and a lot can change, however I would still check out the maintenance costs vs a petrol vehicle.

It's always been said that you have to be doing over 40,000km per year before a diesel becomes an economical proposistion - and that's regardless of which political party is in power or if there is a war in the middle east.18 mths ago I would of said diesel was the way to go,but they have tipped the balance against diesel by upping RUC and registration costs.I used our Diamante for a few days a month or so back,I stopped pretty quick when I saw how much fuel it was using in my 200km per day travels.I hate to think what my Pajero would cost to run with the V6 option,it would suck way more than the Diamante with the same engine.

The Pajero gets 28mpg (sorry,old fulla here) on the open road,which is bloody good for a vehicle that size,my Vanette gets 40mpg,all the time - it doesn't matter if it's empty or loaded to the roof hauling a heavy trailer,slow and steady,typical diesel.That's incredable mileage,double what you'd get out of a petrol van and just shows how efficient a diesel is.But a diesel has higher maintenance costs - 5,000km oil changes,most of the Jap diesels use an expensive dual element oil filter,the fuel filter gets changed every 20,000km,if you are stupid enough to have one with a cambelt they need changing too of course.They take more oil each fill,more coolant.At some stage the injectors will need servicing - but if this is a company car you can flick it before then and let the new owner pick up those costs.

If handling is your criteria you'll have to get a car,and that means Euro,they make the best diesels.

There have been massive advances in Diesel fuel efficiency, engine longevity, and refinement. We don't get to see much of it because only the Euros bring Diesel's in and Kiwis are of course almost paranoid about buying European car. They seem to think that they are fragile or that people will think you're a wanker or a deviant.

Japanese passenger Diesels during the early used import era also put NZers off, because they tended to put Diesel heads on petrol blocks, and natrurally these had a limited lifespan that suited Japanese vehicle licensing requirements. 2nd hand ones over 100,000km tended to fail catastrophically.

Get LPG Fitted from new in a ute you won't loose too much space and now days the installers can fit them in some amazing places.

LPG is 0.70 per litre fuel accon will be the same as if you were on petrol and there is no power loss.

Kickaha
19th July 2006, 09:39
What about a vehicle with LPG or having it fitted? it's around 72c a litre

I would think it would be cheaper than both to run although that would depend on annual mileage as to how soon it would pay for itself

I think only Falcon and Commodore do one as a factory option

The Euros are just car blocks too - the Ford diesel is just the good old Kent block that first came out in the Anglia.I pulled the dead engine out of my Escort van and fitted a 1600 crossflow out of who knows what.Both bare blocks had the same length and height,bolted straight onto the gearbox,bolted on the diesel flywheel.VW Golf was the same,it was the petrol block.As an ex truck mechanic I am disgusted with all these small diesels - FFS,dry liners,alloy heads,cambelts - real diesel engineers just laugh at these things,none of them are made for a long life,the engines last about as long as a petrol engine.Euro vehicles have a much shorter lifespan than Jap cars - no way are they going to put a 20 year motor into a 7 year car.

Although my hilux surf is cheap to run, unlike the 4wds mentioned earlier, I have to get it serviced every 5000km. If your doing alot of km, then its likely to be getting serviced often if its anything like this. However it does not cost that much, but yes its a pain in the arse as Im a shift worker. I do know that when the hilux is replaced, Im going for someting smaller, lighter and faster. Preferablly it wil be running on petrol, unless the fuel costs have gone totally supid. Then I'll just sell the hilux and ride eveywhere on the magic. I reckon a diesel that could hold its courner speed and handle well would be a go. But unless your going offroad, stay away from those Remuwera tractors...

LPG tanks come in two shapes. Big cigars as you're thinking about and those like a spare tyre - they even fit them where your spare tyre fits, but that'll mean losing the spare type and having a spray can fillter thingy-a-bob.

Could go dedicated LPG with twin tanks, one replacing the petrol tank and the other where the spare wheel goes (or another spot). Then bolt the spare wheel somewhere else like tail lid, deck or even up front above the engine like the series Land Rovers have - you're not short are you?

Fuel prices at the moment: Petrol 91: 176.9, Diesel 127.9, LPG 86.9.

Motu
19th July 2006, 10:47
It's only a 5,000km oil change,the rest of the stuff is at the 10,000km interval.If you take it to a dealer they will have to justify the time they spend stuffing around for a 10 minute job,there will be a 30 min labour charge because that's how long it takes to get it in and out of the shop.You can do the oil change yourself easily enough - oh,but you'll get your hands dirty,maybe that's not such a good idea then.....

Oh,and LPG is a dry fuel,it will wear your engine out.






I think we need to dredge up these old wives tales from 20 years ago,most people will have forgotten about them,and the young bucks never heard of such a thing....oh and you must use a special oil...um,a diesel oil for diesels and an LPG oil for gas....um,or else you will destroy the motor,and um...yeah,your clutch will slip too,and your urine will turn yellow if you eat too much vegemite.

LPG is basicly 100 octane and at 70c a liter its pretty brain dead to figure out whats cheaper to run.

higher octane than that I think frosty....bout 150 or something....but the explosive force or energy produced by lpg is less than petrol...

Had an '84 Corlolla diesel yonks ago when commuting, had just about 400,000 on it when I split with the ex, only replaced cam belt and tensioner plus a set of glow-plugs the ex traded it in and it is STILL running around this area, must have 600,000+ on it by now..

I second that, '88 rolla wagon other than the odd head gasket it did 200,000 km towing a boat, bikes and being thrashed. Great wee car. With modern oils most jappa diesels will go 10,000 between services with no ill effects.

No, you don't . You want a proper Alfa, with a proper manual box. The Selespeed is a silly idea. Alfa only did it because poofy people kept whining about having an automatic box. And the Alfa engineers refused to listen. "Eef Juan Manual Fangio, he no usa da automatic, whatta you wanta heem for? Youa thinka you better than Fangio, eh? Whatta wrong weeth you, you noa can changa gears ? You a cripple ? "


So they settled on the Selespeed as a comprimise. Like all comprimises it satisifes no-one. On the GTV coupe Alfa refused even to fit the Selespeed - 'twould FIT OK, the engine's the same as the 156, they just wouldn't do it. You want an Alfa coupe, you changa da gears yourself. And very satisfying it is , too.

Not that I'm aware.
We are one of the few in the bay who do it and whilst we have a waiting list, its mainly due to supply of the kits.
If its a run of the mill Falcon/Camry etc we can have the gear within a day or so if available and fitted when we can do it.
We're have been doing one conversion a week for ages and it suits us as it does'nt tie up a guy when we have a shit load of other work.

I guess it can vary the demand elsewhere.

if you are wanting to save the company money in the long run then look at the price of the vehicle vs the gas it will save,

father in law had a 406 diesel, handled like shit and slow, $25,000 to lease over 3yrs,

we had a 206cc, heavy and slow handled ok $14,000 to lease over 2 years,

you've seen our current daihatsu, 3 years and it's depreciated maybe $4,000-$6,000.

you would have to get some pretty good economy to save $20,000 in gas over 3 years,

All this is pretty irrelevant though, because they are a company they can claim depreciation and running costs on tax, but also have to pay FBT etc if you are going to be using it for personal K's, and your work isn't a small company is it, I'm sure they have some boffins working there who can tell you what gives the company the best bang for buck when it comes to saving them money in the greater scheme of things.

We did a few brand new Camrys before they were delivered to the owners.
They were $3300 each.
We usually get about $3200 - 3600 for nearly all makes unless it needs a few extra things etc.
Did a V8 Lexus last week, $3800, but he wanted a 2nd hand tank.
Looked at a Chrysler Cherokee Jeep today, that could be in the 4s, well probably will.
The owner said, if its under $5000 go for it.

i run a 3.5l diamante on LPG - cost about $2800 to install in 2004, i've done 70000kms since then, it's just gone up to 85c/litre, but still costs about the 1800cc corolla work car. the diamante's for sale though, as i've bought an ST-X Navara ute - 2.5l common rail diesel, 5 speed auto (they also come in 6 speed manual), cruise control, 8 speaker stereo, stretched cab so that my 6'2 son can sit behind me when i'm driving. runs the same suspension height as the 4x4, without the extra weight to drag around. is running at 10l/100km atm, but it only has 3000kms on it. it's a fantastic rig - walks all over the 2wd hilux

Oh,and LPG is a dry fuel, it will wear your engine out.
Even on today's engines where they basically use the engines own fuel injection system instead of slapping another carb on the air intake?

I thought it might only be a problem with carb equiped engines because they might be running wet valves and LPG would bugger them?

That's very cheap. I've heard it's currently $5k.

Dedicated gas,dual fual is a waste of time,it's a compromise - and you don't want to compromise fuel efficiency,that's what it's all about after all.25 years ago at the height of the gas boom I converted my HG Holden to CNG,this was a really good conversion and I did all the little tricks to get my power up on CNG,things you just didn't bother about with a customers car....so this was one of the better conversions around.We put it on the dyno and I was devistated to find I had a 25% drop in power on CNG - you can imagine the state of 90% of the conversions of that time.I didn't do many conversions,I specialised in tuning them - the conversion guys would just slam the conversion together,take the money and the owner drove away.Then they came to me to get it running right.

All the stories about dry fuels,valve and bearing problems were just what we call urban legends these days.Sure there were problems,no denying that - but gas wasn't the problem,it's a great fuel.

Some yes.
Most of them seem to have long gone, well in my area anyway.

We've been doing conversions since the 70s when the old man was one of the first around doing them.
We also get a lot of LPG work related stuff from other garages who still seem mystified by it all.
Plus customers with their private cars.
Theres still shit loads of old Falcons/Holdens still chugging away on it.
You have to do the whole package, install, get it running sweet on it, iron out any bugs, and of course guarrantee it.
Mind you, today's EFI and electronic systems make tuning a breeze, if any needed at all.

Italian cars, there's some feral DNA that goes through them all. Even the old Fiat 850 coupes were like mini Ferraris.
Because they are designed by people who love driving not by corporations that love $

OK OK I heard you the first time.
