yep...my nissan service manual only goes up to 80 000km...but if i look at the patterns and intivals....you only need to do an oil and filter change..... your fuel filter gets changed every 40 000km....so if that hasnt been done, do that too while you at it, check the basic things such as coolant, fuel lines, check air filter, sensors etc thats engine wise
how warm does it get down there??? for 150000 maybe 10w40? i cant remember if thats the one for older engines or fresh engines im not the best with oils....maybe someone else can answer
Penrite HPR 5 is my recommendation. thats 5 w 40 Edit, check all your pcv hoses etc too as part of your service
