Hello. I'm from Bulgaria and reg to this micra forum with great pleasure . I byed Nissan Micra k10 with 1.2 engine 5 speed manual gear box. 1991 year is and this is my first car. I change all consumptives but can't change the oil in the gearbox .... The sting for speedometer is stuck and can't put it out to fill the oil . I go to 2 oil mechanics and they say can't change the oil because the sting is stuck . They spreyed with WD-40 and no result .. What can i do ? Thanks and sorry if my english is not verry well.
