Anyone familiar with this oil. I'm thinking of putting it into my 6.9

The 6,9 is not built for synthetic motor oil and it can do real damage. I hunted a rumbling sound in a 6,3 engine once and the only cure was changing the oil. I used this: http://www.kroon-oil.com/en/products/catalogue/seg_aut/krmo/62/automotive/kroon-oil-motoroils/bi-turbo-15w40/

The most complex systems can fail in the simplest way.

i don't believe in the lord! He's never bought me a Mercedes Benz.

Good oil if you can get it but not sure it would be so great for a motor of that vintage.

IMHO a diesel oil with a lot of zddp would probably be better.

Most oils like that rely on the additive package too much to allow for any real benefit.

Better off with a conventional oil like 10W-40
