Ampol (ASX:ALD) has temporarily stopped operating its Fluidised Catalytic Cracking Unit (FCCU) at the Lytton refinery due to a slide valve issue.
The FCCU is expected to return to service in early May after repairs and the refinery will continue producing diesel and jet fuel.
There will likely be a reduction in gasoline production, but no disruption in supply to customers is anticipated.
The outage may impact Ampol's EBIT within a range of $30-50M, and further details will be provided in its Q1 trading update on April 27.
