Exhibit 99.1 ================================================================================ NEWS RELEASE ================================================================================ FOR IMMEDIATE RELEASE Contact: Larry E. Bell FRONTIER REPORTS THIRD QUARTER RESULTS HOUSTON, TEXAS, October 21, 1999 -- Frontier Oil Corporation ("FTO") today reported net income for the third quarter ending September 30, 1999 of $8.4 million, or $.30 per diluted share, compared to $9.4 million, or $.33 per diluted share, for the third quarter of 1998. Operating income before depreciation was $13.2 million versus $13.7 million for the same period last year. Frontier's operating income was $10.2 million compared to $11.0 million for the third quarter of 1998. This year's third quarter results benefitted from approximately $6.1 million of inventory gains due to the sharp increase in crude oil prices during the quarter. The Company's third quarter results were down compared to last year's third quarter due to a significant decrease in the light/heavy crude oil spread and lower by product margins due to higher crude oil costs. The refined product margin was $6.26 per bbl, compared to $7.14 per bbl in the third quarter last year. The light/heavy crude oil spread for the quarter was $1.89 per bbl, or $1.77 lower than last year's spread of $3.66 per bbl, and was the lowest quarter ever experienced by Frontier. Gasoline production increased 7% to 17,437 bbls per day, distillate production was up 10% to 13,115 bbls per day, and sales volumes increased 9% to 48,984 bbls per day. Refining operating expenses per bbl decreased $.48 per bbl to $2.87 per bbl for the third quarter of 1999 due to higher throughput, lower maintenance costs and lower turnaround accruals. For the nine months ending September 30, 1999, the Company had net income of $7.4 million, or $.27 per diluted share, compared to $14.8 million, or $.51 per diluted share for the same period last year. Operating income before depreciation was $21.5 million versus $31.0 million for the first nine months of 1998. Operating income was $12.8 million compared to $23.1 million in the first nine months last year. The 1998 results include a $3.0 million loss on the early retirement of debt. This year's results benefitted from approximately $12.7 million of inventory gains due to a sharp increase in crude oil prices. This year's results were down compared to 1998 results due to lower product margins and a significant reduction in the light/heavy crude oil spread offset by the benefit of inventory gains. High nationwide inventory levels of gasoline and diesel in 1999 kept margins through June at their lowest levels since 1995 although the third quarter showed significant improvement. The refined product margin was $5.28 per bbl compared to $6.40 in the 1998 period. The light/heavy crude oil spread for the nine months ending September 30 was $2.01 per bbl compared to $4.40 per bbl for the same period last year and was the lowest ever experienced by Frontier for a nine month period. Yields of gasoline increased 8% while yields of distillate decreased 3% in 1999 compared to the same period last year. Refining operating expense per bbl decreased $.20 per bbl to $3.14 per bbl in 1999 due to higher throughput and lower maintenance costs. The Company ended the third quarter of 1999 with $26 million in cash and a debt to total capitalization ratio of approximately 48%. As announced October 20, 1999, Frontier and Equilon Enterprises LLC ("Equilon") have signed the asset purchase and sale agreement and other commercial agreements related to the acquisition by a Frontier subsidiary of Equilon's 110,000 barrel per day refinery in El Dorado, Kansas.

In this regard, the Company also announced today the filing of its preliminary prospectus supplement relating to its offering of $190 million of Senior Notes due 2009.
