Jan 23 (Reuters) - Ampol Ltd ALD.AX reported a 56% drop in fourth-quarter margins at its Lytton refinery in Queensland on Thursday, as Australia's top fuel retailer struggled with operational constraints.
The company in November completed repairs at the fluidized catalytic cracking unit (FCCU) at the refinery after it experienced operational issues.
Refinery margin was $4.60 per barrel for the three months to Dec. 31, compared with last year's $10.52 per barrel.
The company posted total refinery production of 1.54 billion litres during the quarter, higher than the 1.43 billion litres in the year-ago period.
