3 e mai ieftin, nu?
Eu pe ala l-as lua.

1 = Mobil Super 3000 ex 5w30
2 = Wolf Official Tech C3 5w30
3 = Castrol Edge 5w30
Cel mai iefin este Wolf (nr.2) desi datele tehnice par mai bune decat la Castrol Edge.
Nu am folosit nici unul din uleiuri pana acum, dar vroiam sa aud mai multe pareri inainte sa incerc unul dintre ele.

Nu e o alegere rea.

Cred ca asta o sa fac.
Multumesc!
