Suncor's September Oil Sands Production Averages 235,000 B/D

Suncor Energy Inc.

Suncor Energy has reported that production at its oil sands facility during September averaged approximately 235,000 barrels per day (bpd). Year-to-date oil sands production at the end of September averaged approximately 223,000 bpd. Suncor is targeting average oil sands production of 240,000 to 250,000 bpd in 2008.

During the previous two months, the proportion of sweet (low-sulphur) crude oil products was lower than planned due to an unscheduled shutdown of a plant which supplies a portion of the hydrogen used to remove sulphur from synthetic crude oil and diesel fuel. Repairs to the plant have now been completed and startup preparations are underway.

On a monthly basis, Suncor reports production numbers from its oil sands operation in order to provide stakeholders with a more timely review of operational performance. These numbers are preliminary and subject to adjustment. Monthly totals may differ from year-to-date total due to rounding, the impact of sales and changes in inventory. Production volumes will be confirmed when Suncor's third quarter results are released on October 29, 2008.
