It is an oil cooled turbo... where is the confusion ???
If you were worried about 'bad oil' getting into the turbo then you shouldn't have bought a diesel as they run dirty.
Oil and filter every 5,000kms and you'll be fine. As far as the 'quart bottle bypass' I commend you for trying, but I think its a bit much.
