Changed it allready 4 times in four years. First time I had some very dirty oil in it but no metal parts! Then I changed it again few thousand kilometers later and clear oil without metal parts. Now I change it every year before winter. Next time in a few weeks. At the moment I have Red Line mt-lv 70-75W gl-4 high performance for manual transmission.
Still it suffers from being difficult to take the reverse in the morning when cold oil. And still crappy shifting from second to third…
Also, I do have the feeling the lsd doesn’t work every time… on my daily route to word I take the same corner and sometimes the car really understeers and other times it corners very well and I could have taken it at a higher speed. So not much confidence…
Hyundai dealer doesn’t feel much, they say everything works fine.
