Brazil’s base oils output fell to a seven-month low in September amid a sustained dip in production from the country’s largest refinery.A jump in Brazil’s base oils imports and a pause in exports of large cargoes to overseas markets likely cushioned the impact of the drop in output.Base oils output came to 45,900 cubic meters (40,700 tonnes) in September, government data showed..The volume was similar to the previous month and down from typical levels of more than 53,000 cubic meters/month in the year to July.Output fell because of a dip in production at the Group I unit at Petrobras’ Reduc refinery to close to 35,000 cubic meters, with heavier grades the most impacted..The volume was the lowest since end-2023, when the unit was resuming operations after an extended round of plant-maintenance work.An extension of the drop in output into the fourth quarter of the year could increase Brazil’s already-large reliance on base oils supplies from overseas markets to cover its requirements.Brazil’s domestic base oils output accounted for little more than 40% of the country’s base oils supply in the year to end-June..Brazil September base oils imports rise
