Very excellent UOA for a 5,000 mile turbo engine. What laboatory did the UOA may I ask?

Ramatek here in Calgary Alberta Canada.

 

[TeeDub]

What ASTM test method is listed for the TBN??

 

[ktm_525]

doesn't say.

 

[Jaymus]

Why is the calcium so low? Because the engine is new and breaking in? The zinc looks great, makes me want it for my flat tappet engine.

 

[INDYMAC]

Ca is usually supplemented with Mg in GC. But I don't see any here.
