Narrative:
While en route from stl-dfw, aircraft experienced a vibration followed by an oil quantity (r-hand) fluctuation. This was followed by the r-hand oil strainer clogging light coming. Decision was made to divert to tul and appropriate checklists were completed. Engine was operated at reduced thrust and all indications were normal. No emergency was declared. Callback conversation with reporter revealed the following information: the reporter stated the right engine was never shut down, but left in idle power. The reporter said the engine was a P&west JT8D-9 and maintenance advised the engine was changed with no report of what failed internally.

Narrative: WHILE ENRTE FROM STL-DFW, ACFT EXPERIENCED A VIBRATION FOLLOWED BY AN OIL QUANTITY (R-HAND) FLUCTUATION. THIS WAS FOLLOWED BY THE R-HAND OIL STRAINER CLOGGING LIGHT COMING. DECISION WAS MADE TO DIVERT TO TUL AND APPROPRIATE CHKLISTS WERE COMPLETED. ENG WAS OPERATED AT REDUCED THRUST AND ALL INDICATIONS WERE NORMAL. NO EMER WAS DECLARED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE R ENG WAS NEVER SHUT DOWN, BUT LEFT IN IDLE PWR.
