Thread: Low sulphur diesel

wow! how long have you had your vehicle? the Australian Government was fully aware of this problem and allowed for a rebate for any vehicles to have their fuel systems refurbished with compatible seals. I had my old pathfinder done foc must be 7yrs ago. Of course the rebate doesnt apply now.It seems weird that youre only experiencing the problem now.
btw, I dont think you can "keep out of caltex"......I believe they are the only diesel manufacturer north of Melbourne.

It is not only me, the diesel mechanics are full on replacing pumps now and not only Bosh.

HERE is an interesting reading about Canola based lubricity additives

its all the same stuff these days with 10ppm max sulphur so staying out of one you should be staying out of all.

interesting reading about the canola base product.....I primarily use a canola biodiesel 20% mix. I also have td5 which I'm assuming is unaffected by the lower sulpur levels. So it looks like a lot of older fuel injection pumps are going to suffer again. I would have thought that the replacement of seals prevously would suffice.

You can make up for the lost lubricity by adding 2-stroke oil to your diesel. I run 50ppm with 2SO on my puma.

Lol - I always find this stuff amusing. In QLD, all diesel you buy comes from either the Caltex Lytton Refinery or the BP Bulwer Island Refinery.

So unless you buy your diesel over the internet and get it posted to you...

We are now up to ultra, ultra low sulphur diesel (I think) - less than 10 ppm sulphur anyway (australia wide, not just QLD). Sulphur is not a lubricant (despite myths to the contrary), however it is difficult to remove it without degrading the lubricity of the fuel.

BP diesel should have an average cetane number which is higher than caltex diesel, which means it should be a better fuel (in terms of performance anyway).

All diesel sold in AU can have up to 5% biodiesel to improve lubricity (without marking it as B5). This will soon be increased to 10% as it has been in the EU.

And when this happens you can look forward to even quicker failures on injectors and pumps.

Chucaro, that 'article' is old !

There is a minimum mandated lubricity # (it's an actual scar test) for all diesel produced in Australia, and has been in place since 50ppm diesel was introduced.

Early on in the first trials of ULSD in Qld, well before the rest of the country got 50PPM diesel there were rotary pump issues reported, this was the basis for the added lubricant in diesel.

Plenty of us have been running rotary injector pump diesels now for years without issue, and the shaft seal problems have been around since the rotary injector pump was introduced.

It's a non issue.
