No mention of the various cetane numbers in the previous thread.
Australian standard is 46 or above.
But my 200 series requires 48 cetane.
My wife's VW requires 50 cetane.
BP is at least 48 for their diesel and typically 51 for the ultimate ( it used to be higher).
Shell guaranteed 49 cetane some years back.
Could never find out from Caltex what their cetane numbers were for Vortex. Phoned them up and all they told me was it was above 46.
No matter what brand, you are best buying from a servo that turns over a lot of diesel and has been recently built. I've changed my own filters since my first diesel in 1989 and have only ever found one drop of water and not had algae. I don't like supermarket dockets.

We have had our new diesel vehicle for less than a week and I have to say I'm concerned about "bad fuel" and miss-fuelling - I'm almost starting to wish we had purchased a petrol vehicle.

Firstly, you can get bad fuel in a petrol bowser just as easily.
Secondly, I have a diesel LC (1999 - so not high tech) and have travelled all over Oz from north to south and across the centre in all directions, and have had only one occasion where I needed to change an oil filter between services (5-7000 kms) - and that was travelling from Sydney to Brisbane - not out in the sticks.

Carry a spare filter, learn how to fit it, and get it changed regularly when servicing. Incidentally, I've done over 350,000 kms since I bought my old girl which has now done 502,000 kms.

Gerard,STOP RIGHT THERE!!.I've never had diesel.But after my previous thread & the advice & suggestions,I'm becoming more comfortable.This has been a MASSIVE saga,but I'm very happy (so far) with my NEW Colorado.Economy is great,driving comfort is great.Buy at reputable pumps,where the trucks stop,& be vigilant.Read forums & ask questions.Ask your vehicle manufacturer.Listen to people,but remember,EVERYONE has an opinion.Good luck with whatever your vehicle is.

If you're greatly concerned about getting bad fuel in your Common Rail diesel, then invest in additional fuel filtering, particularly a setup that stops water from getting to the fuel system.

There are numerous sellers of additional filtering systems for diesels. You need a minimum of 2 micron fuel filtering, and a filter capable of allowing a fuel flow that doesn't create restriction in the fuel flow rates. See Stanadyne Fuel Manager as a typical example.

CR fuel systems must be 100% protected against even the tiniest amount of dirt or water getting into the fuel system.

The simple reasons being, they operate at enormous pressures, and with such fine tolerances, that any water or dirt in the system immediately causes major and very expensive damage.

Cheers, Ron.

We have just returned from 6000 Klm trip around North Qld, my brother in law was leaving the day after us and we planed to meet in Mareeba.

He made it as far as Mirriam Vale where he had one piston holed due to dirty fuel.

He had an extra filter but I think it was 20 micron pre oem filter and apparently was not good enough for the job.

He now has a new short motor, hopefully it won't happen again.

Put the best quality filter you can buy it will be cheaper than a new motor.

That is one reason why I bought myself a petrol vehicle.
Cost analysis over 50000 kms tells me I'm no worse off expense wise and I don't feel nervous about it.
