1Place eggs, oil and salt in food processor bowl. Cover and process until smooth. Add flour. Cover and process about 10 seconds or until dough leaves side of bowl and can be pressed together with fingers. (If dough is too dry, add a few drops of water; cover and process 5 seconds. If dough is too sticky, add a small amount of flour; cover and process 5 seconds.) Remove dough and press into a ball. Cover dough with plastic wrap or aluminum foil. Let stand 10 minutes.
2Divide dough in half. Roll one-half of dough with rolling pin into rectangle 1/8 to 1/16-inch thick on lightly floured surface. Loosely fold rectangle lengthwise into thirds; cut crosswise into 1/4-inch strips for fettuccine, 1/8-inch strips for linguine. Hang pasta on drying rack or lightly floured towels to dry. Repeat with remaining dough.
3In 6-quart saucepan, heat 4 quarts water to boiling; add pasta. Boil uncovered 2 to 5 minutes, stirring occasionally, until firm but tender. Drain pasta; do not rinse.
