Narrative:
On flight from casper, wy, to fort bridger, wy, via lander, wy, oil filler cover not properly tightened. After 1 1/2 hours in-flight noticed a few drops of oil on windshield. Checked oil pressures. It was decreasing rapidly. Made a precautionary landing on a straight and level stretch of highway 287. Taxied into a turnoff off the highway. Dipstick showed 1-2 quarts left, left side of air frame covered with oil. With assistance from wyoming sheriff and state police, got 7 quarts of oil at lander FBO. Cleaned plane, refilled oil (oil temperature had not risen), started engine, runup ok. Police stopped traffic (only 3 cars). Made uneventful takeoff. Proceeded to lander. Had plane checked -- ok. Proceeded to fort bridger, wy, with no further problem. Was flying in company with 39 other aircraft on a trip along the oregon trail. 2 planes circled until determined we were in no trouble. Problem was pilot error in not adequately securing oil filler cap.
