Hi Diesel 'n Dust,
Hmm, You've got me thinking now.
That's what the little service sticker says on the windscreen(15w-40)
Just went out to the shed and I have a 5lt that has 15-50W and its a HPR15. I think and I could be wrong here, they have changed the grading to do with, Is it the ash or something like that?
Mazcan,
Catch cans are usually used on the bigger diesels, 6 cylinders. The build up of oil vapor in the cranking system I believe is not real good for the turbos. There is a hose that comes from the rocker cover and goes to the the turbo side of the air cleaner box, this oil vapor is burnt in the cylinder chamber and cause some smoke at the tail pipe as burnt oil.
A catch can is put in this hose, the motor/turbo sucks the oil vapor out of the cranking system and it is pulled through the catch can that is full of something that looks like steelwool. This catches the oil before it is sucked back into the intake. The oil can be drained off.
More turbo high performance motors will have an oil Catch Can of some type.

I bought the can off eBay
Here at the time they were about 48 bucks.
Then I got some 22mm hose and a few fittings, clamps fitted it. Of cause you could get the fittings welded into the can,so there was a reduction from 22mm to 12mm barbs, this would allow a higher air volume flow through the can.
As I mentioned earlier I did notice the oil staying cleaner for longer.
It can only benefit the motor in the long run.
Hope this helps guys.
