Narrative:
Aircraft overnighted. The morning crew made a maintenance log entry requesting oil service. Contract maintenance (FAA a&P) svced the #1 engine with 9 pints. I believe gpm oil consumption monitoring program procedures were not correctly followed. External oil leak check should have been complied with prior to departing; as the engine had not gone over 20 flight hours without oil service. The #1 engine also should have been placed on an oil watch prior to departing ZZZ. The #1 engine has had a recent history of increasing oil use and is averaging a .52 pint per hour consumption; over the past 103.8 flight hours. Which per procedure requires further inspection prior to aircraft being dispatched.

Title: AN EMB145 L ENG OIL WAS SVCED AT A NON MAINT STATION BY A CONTRACT TECHNICIAN. LOGBOOK WAS NOT CHKED FOR OIL CONSUMPTION AND A REQUIRED LEAK CHK WAS NOT ACCOMPLISHED.
Narrative: ACFT OVERNIGHTED. THE MORNING CREW MADE A MAINT LOG ENTRY REQUESTING OIL SVC. CONTRACT MAINT (FAA A&P) SVCED THE #1 ENG WITH 9 PINTS. I BELIEVE GPM OIL CONSUMPTION MONITORING PROGRAM PROCS WERE NOT CORRECTLY FOLLOWED. EXTERNAL OIL LEAK CHK SHOULD HAVE BEEN COMPLIED WITH PRIOR TO DEPARTING; AS THE ENG HAD NOT GONE OVER 20 FLT HRS WITHOUT OIL SVC. THE #1 ENG ALSO SHOULD HAVE BEEN PLACED ON AN OIL WATCH PRIOR TO DEPARTING ZZZ. THE #1 ENG HAS HAD A RECENT HISTORY OF INCREASING OIL USE AND IS AVERAGING A .52 PINT PER HR CONSUMPTION; OVER THE PAST 103.8 FLT HRS. WHICH PER PROC REQUIRES FURTHER INSPECTION PRIOR TO ACFT BEING DISPATCHED.
