OK guys, cool your jets.

Switching to DT40 from another oil you have two choices: Do a "belt and suspenders" pre flush to remove every trace of the old oil, or just do a simple oil change and switch to the DT40.

We have many customers using the DT40, myself included, and none of the cars were pre flushed. To date, all of the UOA's look excellent.

And you really do not need to change your oil every 3K miles, 5K is just fine.
