One of the work utes just had a service. I saw a sample of the engine oil that was changed and it was like thick custard. It has done 20,000 km since previous service.
It is a Navara DX 2.5 turbo
I don't spend much time at the workshop as I'm usually out on field work. When I get more information I'll keep you updated.
Tho oil is thick like honey or golden syrup.
