Type of Engine Oil

What oil is specified for a VTEC? How long do the cams last?

Can you give details? There's plenty documentation out there that ZDDP ceased to be used because of cats. But not that a better alternative was found which was cat friendly.

Do you have personal experience that modern oils are just fine on all older engines?

Sequence iiiG for the US or MB229.1 sets lower wear liiits than all the previus ones

HOw would one know that it's the new oil that caused ones ancient engine to wear out? The major influence on scuffing wear is break in, perhaps somebody could devise a test to measure it & then test a lot of engines against it. Then they could call it a published oil standard and one could check if the oil one was buying conformed to it.
