Thread: 20k service on new 90 is too long

so oil and the design of its system doesnt play a roll in cooling, and therefore how much that would effect the break down of oil.....

Of course it does. But if you aren't overheating it, then it's all working as intended.

I feel we could be going in circles here.....since the system is designed as a whole, Im sure any engine builder takes both coolant and oil systems in to count for total cooling and if they feel their system is fine, then job done. Again, it wouldnt be the first time that a system has been tested in Oz.

What is the sump capacity of the Tdci?

No idea, but someone here will tell me.
My Isuzu was around 7 litres. Now 6. 16,000km intervals in a truck at 8T gross back in 1985.
My 2.2 tdi nissan work car is about 5 litres and 20,000km intervals. It is a 1.4 ton car though, not a 2.2T rover. It's not commonrail so doesn't run as clean as newer engines.

Current Peugeot/Citroën diesels only have a 5 litre sump and call for 20,000km OCI's with a low SAPS, full synthetic 5W-30 ACEA C2 oil.
These are fuel economy oils designed to protect the DPF and cat.

I think an ACEA E4/E6/E9 10W-40 oil (low SAPS so safe for the cat and DPF) may find it's way into the sump
I'm a little concerned with TBN retention with some of these low sulphated ash oils over 20,000km in city/stop start/short trip use, although it'd probably be fine where we are, it gets mostly 30km highway runs.

It only gets down to -7*C here so not too cold, a 10W will be fine at 5:45AM and it's pretty dry too, one of the drier areas of Oz, although I think our average annual rainfall is double of where Dougal lives, but to be fair he is in the driest part of NZ

I lived in one of the wettest towns for a few years. 2.5m a year. It got wetter out of the towns and closer to the hills.
Here vehicles last forever. There they would completely disappear into a mound of rust flakes over the engine block.

I had to run 5w30 in that nissan. Hydraulic chain tensioners wouldn't play ball in cold winter starts. But I have a spare engine anyway.

The wettest area in Oz I think is around Tully, somewhere above 3.3m/year.

Up where Roverrescue/Steve is I think it's just under 2m/year.

It's in the tropics, it's wet.

I'm guessing the west coast of Tassie is like the South Islands west coast, cold and wet, but not too many live there.
