Who knows?:D. Fraser's theory stands up as far as using OAT goes, but mine had glycol in it that was put there by a major dealer. This in turn sounds like it is different from what BMW put in the X5...Quote:

I've replaced like for like and gone with glycol. Until I can prove otherwise, I'll leave that there.
What is in yours at the moment Harlie?
Hard to see, looks blue to me.Quote:

So it could be the factory BMW coolant. Will have to ask the stealers I think.Quote:

Castrol net lube also specs Castrol anti freeze NF which is in this bulletin. Its colour is green/blue. Its a glycol coolant but must be a additive in it that the coolant level sensor must have to work.
Here is the product data

hmmm got me thinking about mine - its rather blue in colour, and I have topped up twice with a bit of demineralised water and nothing else as I didn't want to put green glycol in from the P38/classic or red glycol from the mrs magna.
Then again I have been very lazy and looking at the service history its done just over 100k in 4 years on its current coolant.
Ok, so the LR bulletin (woko post) states that Castrol Antifreeze NF is the go. It is a rebadged version of the dealer part PDA500310.
According to the LR bulleton it is a ethylene glycol ... with a silicate non-phosphate corrosion inhibitor
and the Castrol document adds Castrol Antifreeze NF is a nitrite, phosphate and amine free, fully formulated glycol coolant.
It is blue in colour. Some interesting research has revealed that not all green coolants are the same and not all blue are the same.
I was at Repco this morning (25% sale in QLD this weekend, top up on fluids for upcoming servicing). They mainly stock Nulon and reading the Nulon doco shows that NULON BLUE LONG LIFE does not match the description given by LR and Castrol. However their green Long Life Concentrated Coolant is a closer match. Quote Nulon Long Life Coolant is a low silicate formulation containing no nitrate, phosphate or amine.
So it is obvious that green does not necessarily equal green, and blue does not necessarily equal blue.... And I’m too chicken to change colour from what’s in there.
Big question – Where can we buy Castrol NF?
Mmm, seems that we are beholden to the OEM coolant to me.
Unless we can uncover what the magic potion is that it contains that keeps the low level sensor happy.
I have not had any problems since the OEM coolant has been reinstated.
I quiet agree....Green is not Green and Blue is not Blue.
Here's the QLD stockist for castrol. http://castrolthebighaul.com.au/stockists-qld.pdf They may not keep it in stock but they would be able to order it.Quote:

I have not been successful locating either in stock but the favoured Castrol only comes on 20 or 206L drums. As we need about 6L for a change only way $ viable is to split a drum 3 ways. Anyone in BNE area up??
The Valvoline is available in all sizes from 1 to 205L so a 5+1 would do it.
Or it is to the dealer as they will have a 205....
Penrite seem to have a product that meets the BMW specs for coolant;
