Its quite surprising that Toyota Phil still approves CF-4 diesel mineral oil (of their own Toyota relabelled oil) to be used on the D-4D.

I mean they could have gone for something rated at CI-4.

Anyway, warranty ends this coming May and I'm free to use better oil (and filter) in future services.

i think its because of our euro2 fuel.
