2012 GC Overland diesel in NZ ,always had eight litres put in it since I have owned it,never a problem.Been using Penrite 5w40 Enviro will change to the 10w40 Enviro when next change is due.Also put in half a bottle of Penrite zinc additive ! The independant Jeep guy in NZ I know has been putting it in his two GC diesels for three years ,no problems yet ..he has Rebuilt a couple of VMs,said the width of the main bearing shells was very narrow and the main bearing locating tabs were nearly non existant.He said very little difference in VM motors
from 2012 to 2018.He has fitted a early motor into 2018 with no problems.
