By the way the shipment has arrived in the post office in North Hollywood. My friend is picking it up today or tom. Can't wait to get the filters. I'm having it shipped here together 8-10 (5 quart) bottles of Mobil 1 TDT.

Delo silver is a good oil, can definetly run longer than 3kms, It does have a TBN of 9.6

Delo siver can be considered semi synthetic as it has group III oil blended in with it. and it has greater than 1000ppm zinc so that's a good thing. If it's anything like the Delo 400 it probably has a good dose of moly and boron in it as well. Delo oils are for commercial vehicle use so they are stout.l
