bollocks. its probably got a lot to do with fuel storage and vehicle maintenance. I know plenty of common rail tractors ,filled from farm storage tanks(apparently we are the worst) done over 10 000 hrs without problems

I don’t run gull petrol in my prado as I’m not sure how good The petrol is. Anyone know what there diesel is like compared to the other brands. ?

I had issues with gull petrol in my old Camry and got less kms per tank than other brands so avoid it for diesel as well. I use allied or bp for my ute. I also never use it for short trips like to pop down to the shops etc. It's also serviced every 10,000 kms. It was an expensive vehicle for us so take good care of it.

well you got to use a additive if you suspect fuel is not up to standard. What it is or was its always contermination. so manufacturer of fuel cant be lamed as lawyers will get them off with proof. To mitegate this you have to run your own additives or take a gamble russian roulette springs to mind. . Why do you think almost all old diesel with old pumps are gone? they have all been killed off by people who stated on here they never had a problem. they probably also claim the earth is flat. the ulsd-changeover was causing mass killing with fuel having close to nill lubrication. The reasons i do know now in full detail and you cant sue manufacturer as it was a act of god and they wont pay just like the swiss dont pay on earthquake damage or storm damage insurance. hence why i have 0 insurance

what kills new diesel is short trips and emission garbage its why vw have had a special software as per diesel gate scandal. bad fuel can aid that progress to nuke them of course because ultra low sulfur and wither summer diesel switch schrinks and damges seals They shrunk and go hard= leaking pumps . Sulfur is a lubricant and sulfur swells seals= why a old pump would never leak or almost never. ulsd ultra-low-sulfur is required for diesel cat-filters just like lead had to be removed from fuel from petrol. That is the reason for ultra low sulfur fuel= why you add chemtech or any other good diesel additive every now and then etc to your fuel

no, nz fuel is pretty good since they did the old "dob in a smokey diesel campaign" and of course the switch to low sulphur diesel. i think it was gull at the time imported diesel (most of nz diesel is made at marsden) which was cleaner and more economical to run, which a lot of people switched to.
most problems these days is due to water in the fuel tanks. old leaky tanks. however due to law suits etc the companies are usually pretty good. if you want bad diesel try aussie. huge problems.
one of the issues here is nz still has a lot of really old diesels whose seals don't work well with modern low sulphur diesel.

I have been using 2 stroke oil in my 2013 d40 navara since new, quiets the injector rattle, more power, and the better economy basically pays for itself (200/1 ratio, or 1/3 liter each fill), same as mercedes did on a major Europe road test of their vehicle range. Still never even seen the dpf light come on, at 70k now, but is always mixed rural and town use, very few short local trips. I always seem to get an extra 20 - 30km per tank (@ 400km/tank), out of BP.

I have a NZ New 2001 Merc Sprinter camper weighing in at 2400kg. It has the OM601 2.2l CDi engine making just 60kW/200Nm so it gets a fair hiding under normal use. It has 365000Km on it so far and is running like a train, perfect & smooth. NZ fuel hasn’t killed it yet.

Rubbish If you fully fill and drive until you are on E and then fully fill you will never have a problem as well a changing fuel filters on time, You only get problems if you don't change filters on time and half fill the tank which causes increased condensation in the tank.

Answer to the question, No it’s not the diesel that’s killing engines , it’s the piss poor servicing that kiwi’s give to their Diesel engined vehicles.

My argument for a long time is that modern Diesel vehicles are designed to run on ZERO sulphur fuel which is what is available almost world wide. NZ doesn't have that we have "low" sulphur fuel which plays havoc with modern diesels. The cost to improve our diesel is in the billions.

the sulphur screws with the catalytic converters but thats not what typically fails. the big issue with diesel is that its lube properties are now at minimum, so it doesn't handle any watering down or contamination like the old full sulphur diesel does. trouble is you still get gas stations pouring the fuel out of miss fueled cars into the gas station diesel tank (because its really expensive to send it away to be dealt with). and water from bad gas stations, or as we found, left over from the car manufacture.

So what about AdBlue diesels, common rail, turbo, should do the job using NZ diesel fuel ?

I heard a rumor that marsden point refinery might close down to fix the problem and import all our fuel. Either they spend billions or shut it down, so my money is on it shutting down.

Adblue is not added to the fuel it is injected into the exhaust system

afaik there is an upgrade they are doing soon. i think it was in the news last year.

They have spent a lot already but i think the technology is beating them. I hope the rumor is wrong.
When people like Elmer Yuen are talking of a potential hot war between the US and China while NZ analysts looking at the figures thinking it might be a good idea to close down only NZ's oil refinery. I sure hope the NZ analysts like walking and cycling or riding a horse; then again are the NZ analysts all driving Teslas now(and lost touch with the common folk)? Marsden Point is small scale and has high electricity prices etc.
NZ in 10th equal place on the global diesel quality scale. Places like Sweden and Germany have had low sulphur/ lower aromatics diesel for years.
NZ's low octane petrol better than Victoria's/ Aus low octane petrol.
