well everyone (almost) here has a different opinion in this subject ..
ill just put a list for you with the most recommended/used oils here :
All are 5W40
Castrol edge
Mobil1
Elf evolution /900sxr (not sure if they are the same)
Shell ultra helix
some uses motul 300v too /Motul 8100
fuchs race pro s
you can get from opieoils
P.s also millers but i cant remember which type exactly .
and if youll need gearbox oil too so go for ELF Nfp 75w80 (make sure its the new formula-that meets the requirements for TL4 boxes)
or Fuchs 75w80 -those seems to be the most used in these boxes(i highly recommend the new nfp one)
