Narrative:

In the morning; we had a short flight to ZZZ following a weather divert the previous night. On climbout the right engine oil pressure fluctuated low. The quantity indicated 15%. The QRH advised monitoring. We landed ZZZ without incident. Local maintenance found a serious oil leak and added 9-quarts of oil to the right engine. We ran the engine as prescribed and a significant leak was detected. The cowling and engine was quite oil covered. Company maintenance sent two mechanics on a road trip to replace the starter. The starter had been replaced the previous day and metal shards [that] we assumed were from the previous maintenance; were still in the engine cowling. I considered the evidence of the previous maintenance to be very sloppy. The following morning we reported in to reposition the plane to ZZZ1. The mechanics had fixed nothing [the previous night] but done two run-ups and determined the oil leak to be minor. During the flight [from ZZZ to ZZZ1] the engine oil quantity dropped 5% every six minutes and would have run out before ZZZ1. I made the decision to divert to ZZZ2. I was astonished that maintenance then expected me to resume the flight to ZZZ1 after adding oil [again]. I was also astonished that the chief pilot I spoke to; expected the first officer to fly the aircraft after my emphatic refusal to do so based on serious safety concerns poor and sloppy decision making and maintenance diagnosis. Aircraft sent on flight with severe oil leak after several hours of maintenance. Continued insistence that this plane was airworthy after precautionary divert.[recommend] don't keep pouring fluids into leaking systems and failing to properly diagnose or fix the problem. When a captain refuses to fly an un-airworthy aircraft; take that very seriously. Airline transport pilot. Reposition flight.

Title: A CRJ-900 Captain reports about a continuing Right Engine oil leak that led him to refuse the aircraft as a non-airworthy aircraft. After a previous short flight; nine quarts of oil had been added to the GE34-8C5 Right Engine with no other corrective action. That flight was followed by the Right Engine Oil quantity dropping 5% every 6 minutes; causing total oil loss prior to destination. Aircraft diverted to the nearest suitable airport.
