Oil change and BPD system

[Arizona Dave]

I have about 5K miles on my new engine. Because I planned on dumping the oil three times during the break in, I used Rotella to keep the costs down.

This change is going to be Mobil1 TD. Are there any tips to getting a more thorough draining of almost all of the conventional oil out of the entire Bullet Proof system so that the synthetic has a fresh start with any residual conventional mixed in with it?

no worries, as soon as you unscrew the filter its gonna make a mess everywhere. I would just try and minimize the mess and not worry much about the residual conventional oil in the system mixing with the synthetic oil.

It'll clear out with a few oil changes. Don't worry about it.

Any specific reason for the Mobil1 instead of the T6?

If you're worried about mixing synthetic and conventional then mixing synthetic and conventional of the same brand would be a better option if I remember correctly.

Personally I wouldn't be worried about mixing brands or syn/dino as long as you're not doing it every oil change. Like PGreen said after a few changes the old stuff is as good as gone.
