FOR IMMEDIATE RELEASE

May 04, 2005

                  GIANT INDUSTRIES, INC. ANNOUNCES RECORD
                     FIRST QUARTER 2005 NET EARNINGS

Scottsdale, Arizona, May 04, 2005 - Giant Industries, Inc. [NYSE: GI] today
reported net earnings for the first quarter ended March 31, 2005 of $10.1
million or $0.80 per diluted share. This compares to net earnings for the
first quarter of 2004 of $4.5 million or $0.50 per diluted share.

Fred Holliger, Giant's Chief Executive Officer, said, "We are pleased to be
able to report record first quarter net earnings for the second consecutive
year. Strong financial performances by our refining group and Phoenix Fuel
contributed to the record earnings. Net earnings for the quarter were also
positively impacted by a $2.1 million after-tax insurance reimbursement.
Refining margins at our Four Corners refineries and Yorktown refinery were
solid for the quarter and we believe that current refining fundamentals are
comparable to the same time last year. Operating income at our Four Corners
refineries was more-or-less even with the prior year level; however, Yorktown
operating income was approximately twenty-two percent higher than the first
quarter 2004 level."

"Phoenix Fuel continued to perform well financially as they achieved growth
across the board in the first quarter of 2005. Operating income in the first
quarter of 2005 were up in excess of seventy-five percent over the prior year
comparable quarter as wholesale fuel sales volumes increased in excess of six
percent and cardlock fuel sales increased approximately thirteen percent.
Phoenix Fuel continues to provide consistent cash flow and growth in the
markets that it serves."

"Retail operations profitability was negatively impacted by lower fuel
margins in the first quarter of 2005. Operationally, our retail group
continued to perform well as same store fuel volumes increased by more than
five percent in the first quarter of 2005 compared to the first quarter of
2004. Merchandise sales increased about one percent in the quarter over last
year's first quarter level. So far in the second quarter, retail fuel margins
have strengthened and fuel volumes and merchandise sales continue to grow
relative to the same time last year."

Holliger continued, "In addition to our strong operating earnings, we also
continued to strengthen our balance sheet. We recently completed the sale of
approximately one million shares of common stock with the net proceeds to be
used to redeem approximately $19 million of our 11% Senior Subordinated Notes
on May 5, 2005. As a result of these transactions, we will now have reduced
our debt from approximately $450 million to $274 million and improved our
debt-to-total capitalization ratio from 76.8% to 52.4% since June 30, 2002,
the month following the acquisition of the Yorktown refinery. As a result of
our past debt reduction initiatives, we have reduced our interest expense as
evidenced by the $2.4 million or 25% decrease in the first quarter of 2005 in
comparison to the first quarter of 2004. The redemption of the 11% notes,
mentioned above, will further reduce our interest expense on our Senior
Subordinated Notes by approximately $2.0 million per year. Obviously, we have
made great strides in improving our overall financial health and this remains
an important goal in the future. We believe the significant improvement in
our balance sheet, coupled with strong earnings, have now repositioned us to
pursue growth opportunities to further improve shareholder value."

5, 2005 to discuss this earnings release and provide an update on company
operations. The conference call will be broadcast live on the company's
