Ya, I heard several version also but one thing stands out. Whatever you do, do not run at constant speed, vary the speed or rpm. Hope that helps.

That's also my exact worry. I know Delo 400 15w40 uses Isosyn Group II+ base oil but are unsure of the CXJ. Since our diesel fuel here are of high sulfur type, I decided to play safe by using Delo 400 but change it slightly more often to counter the slightly lower TBN. Thanks for confirming my fear.

My engine oil has ALWAYS turned black after a couple of hours regardless of whether it's a new engine or not. At least that holds true for my previous 2 brand new engine, both Isuzu's and builder of the Duramax.

Now I know most people here are American and API is the world's most well known oil standard certification institute. But I have reason to believe the ACEA and JASO are more stringent on oil standard then the API. In another word, ACEA & JASO oil are probably better. From my reading on the net...
