Aircraft
The aircraft had a history of oil consumption. The inbound flight was serviced and the Technician said it took the maximum oil allowed. He said it was at the limit on usage per flight but still within limits.  Thirteen minutes into the flight the oil level dropped 8 qts from 18.5 at takeoff to 12.5 and a few minutes later down to 12 qts. At the time I was PM (Pilot Monitoring) the Captain then transferred me to the PF (Pilot Flying) and ATC duties. The Captain contacted Dispatch and [Maintenance]. He came back from the conversation and said they agreed we should divert. After determining we would be overweight for landing; the Captain [advised ATC].  We landed at a descent rate of 200 FPM or less. The Captain and I accomplished all company procedures and checklists.  I didn't think it was necessary to file but due to [advising ATC] the Captain convinced me we should.
In talking to the Captain from the inbound flight we found that the aircraft had been using a significant amount of oil in the left engine. The Mechanic reported that he had put 7.5 pints of oil in the left engine it was indicating 18.5 qts. He told us that it was right at the limit on usage and we were legal to take the aircraft.At takeoff we were still at 18.5 qts. 13 minutes into the flight we were indicating 12.5 qts and at 25 minutes we were indicating 12.0 qts. I called Dispatch and we talked to [Maintenance] and I decided that we should divert.The landing was overweight at 149;000 lbs.; and the sink rate at touchdown was 200 fpm. I [advised ATC] due to the overweight landing. Upon gate arrival; I contacted Dispatch and made an entry in the [logbook] for the mechanical discrepancy; and one for the overweight landing.
A320 flight crew reported high fuel consumption after takeoff resulting in a diversion.
