Our current Puma Defender uses full synthetic and LR says 20,000 km services, but our indie British Offroad advises 10,000 kms, which I'm following.
So just interested.

Yep, full syn in the Tdi and the TD42T Nissan, which was supposed to have 5,000km oil changes.
At the time that was an oil change every 2.5-3 weeks, I kid you not.
12.5 litres and two oil filters.
I quadrupled that oil change interval easily with a decent syn oil, but I only knew I could with oil testing and observing trends.
The Tdi I ended up at stock intervals, it's bloody hard on oil. IMO a limited sump capacity for the loads involved and not enough oil cooling kill oil quickly.

I bet you were told you shouldn't use a synthetic oil in the Tdi as it was 'old school' and the clearances were too large?
Or It was too slippery?
Both are a nonsense.

Yep, that's pretty much what I was told. Something about full synthetic being for engines with finer clearances, from memory.
Interesting.

I sample engine oils at every change, diffs, power steering, AT and transfer get done regularly as well. Looking at oil samples is just one part of my job so I do it mainly for interest sake, but I also like the fact that I can get a possible early warning on any potential issues before failure.

I'm actually going to be changing my engine oil cooler as a response to coolant in the engine oil that I've noticed during routine sampling. I'm not 100% sure that its the cause but it seems to be a more likely source than a head gasket failure from what I've read

I absolutely respect anyone doing it for interest sake. (or if its part of your job).

Is oil nerd a thing ?

Thread update; I heard back from Pacific Land Rover yesterday and Land Rover Australia have agreed to pay 100% parts and labour for a new engine and anything else required - which is great news and a huge relief.

Parts are being sourced and then it'll need 5 days in the workshop, so don't have a date yet for it to be returned, but hopeful it will be this side of Christmas.

Fantastic news. That is a great outcome.

nerd tendencies can be applied to lots of applications, mechanical things being one of them
