Subaru 2.0 diesel '10 7200km Amsoil AFL 5W-40

Hello,
I think it is best UOA on that engine with closed DPF MY10+ (regenerated by fuel) so far. It seems to be better than this:

AFL was 3rd oil in this engine. The engine was flushed/cleaned (Amsoil FLSH used) while changing this AFL to another AFL fill to reduce factory Si as much as possible and see if it helps with copper somehow. Oil consumption has been reduced to 0,4L / 4kkm after engine flush (next sample 4kkm ready for UOA).

Comments welcome.. ;-)

Well, it looks good, but you already knew that.

I sure wish we could get that engine here in the states.

Another UOA from this Subaru diesel - AMSOIL AFL 5W-40 used again after engine flush (Amsoil FLSH) - look at Cu and Si levels! The car was driven very fast this 4kkm so Fe is higher a bit than expected. Fuel injectors cleaned with BG244 and Amsoil ADF diesel concentrate added to each tank - no fuel in oil, no issues with DPF.

Why not use Amsoil's Diesel oil?

We're afraid of DPF and soot there (due to higher saps of DEO) because the DPF in Subaru boxer diesels is regenerating using fuel and then it gets into oil and unfortunatelly it is designed for # of cycles. Warranty sais 5W-30 ACEA C2 or C3 is allowed only.
