Look under improved deposit control.

It's also API/SM and JASO MA rated

It's kinda sad that even an informational thread to provide more data as to how my engine is lasting 150K without catastrophic (read: bearing) problems, always matriculates into an oil pissing war.

I'm not forcing anyone to use what I use or do what I do. If you have the brains to buy an M3, then you are more than capable of figuring out your own maintenance routines. I'm just providing the community another data point to consider.

Anyways, like I said, if there is that much detergent inside the T6, then it is certainly working. Or, when do you predict my engine will grenade? Just passed 151K coming home from work btw.
