the engine has done 180 000. the car was running fine before i added the oil. do u think its jsut that i have overfilled the engine oil?

hi, im really worried and stressed here, seeking advice. i recently bought celica 94, when the dashboard indicated that it need engine oil, so i bought 4 litres of shell engine oil for normal engine. i put all 4 litres into the engine. the next day, when i started the car and drove for about 1 kilometre. there were huge amount of bluish smoke coming out, i really got scared. so i parked the car on the street. where should i do? does it mean the engine is useless?
