All sounds like a bit of a wank , just use what the book recommends, it's a little diesel engine not a friggin v8 supercar!

the manual does not really say; use 5 w-40 or 10w -30, it mentions a variety of oil weights for the climate i live in , so lets say max 40 degrees and mininum 5 degrees, whats the oil recommended for these temps ???

I would be using 10w 40 all year round if it was my engine, you live in QLD mate it don't get to cold or for that matter to hot either , not if your on the coast.

I'd agree with above. Unless you are getting below zero, a 10w 40 will be OK.

So not sure if this is the place to bang a question about the before mentioned oil cooler, but here goes.
Travelling back to the farm over Christmas, got back and notice oil residue down the side of my ute. Pop the bonnet and everything is coated in oil.
Now, no movement on the temp gauge, no warning lights, nothing. I look to the coolant bottle and its full of engine oil. Pop the radiator cap (once cooled) and she's full of oil.
Currently sitting at the Nissan sick bay with them fighting the people I got extended warranty through.
My question is people, anyone had this issue with the yd25 d22 and would there be any internal damage as a result of this?
My Nav is a 2013 and serviced as per factory requirements.
Any help is appreciated

Sounds like you have done a head and oil has got into the coolant or the oil cooler is leaking oil into the coolant?

Yeah my initial thought was the head also however speaking to different people they are suggesting a leak from the oil cooler. I'll keep you updated. The mechanic at Nissan reckons they have never seen an oil cooler fail on a d22

sounds like a cylinder head or cylinder gasket issue, the excess oil in radiator is blowing out of the overflow line , this is why its all over the place. oil in water only comes from certain problems such as mentioned or a cracked block.
lets hope its neither . good luck.

So got word today that the oil cooler was cactus which sent oil into the radiator. The bill comes to a smudge over 4K, which includes a new radiator, oil cooler, thermostat, cooling lines/hoses and labour. Let's bloody hope the extended warranty people come to the party!
Should I ask them to check the head whilst it's there?
Off to qld in March and I'd hate to have this happen again on Fraser.

well thats good news even though its a shame this happened. the price sounds abit steep just to supply /remove and replace those items, then again thats genuine spare parts for you. wouldn,t hurt to ask them to give the engine a compression test while they have your car seeing its a warranty claim.
