Exxon and Texaco, the two largest oil companies in the United States, yesterday raised the wholesale price of gasoline with other companies in the industry. Since yesterday, both gasoline prices have risen by 1 cent. The owner of an independent gas station that buys gasoline from any company must decide whether to pass on the increased costs to their customers. Both companies raised their prices in April. Under federal energy regulations, the price of petroleum products can be changed once a month. At present, the national average price of a gallon of ordinary gasoline is about 59 cents. Oil analysts attribute the rise in oil prices to higher gasoline prices as drivers drive more in warmer weather. The rise in prices represents a \"recovery in part of the rising costs\", Texaco said \". \"Exxon USA, a subsidiary of Exxon, the largest oil company in the United States, said it had reduced the price of jet fuel by 1. 5 cents per gallon Yesterday, Kaiser Aluminum and chemical became the last major aluminum producer to increase production with other companies.
