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.

That is what I though as well. I will be changing this weekend hopefully. This will be my winter change and will probably have less than 2K miles when I do my summer change in April.
