just back from 6 week trip up north---not far bourke --lighnng ridge brisbane ---home via wellington and forbes done 5.500 k no problems except for using 10ltres of oil (oh dear)
using that much oil i would expect to see smoke but none noticed and no leaks either so whats up .
its an old LJ 2.2 diesel with only 169.000 ks starts and runs extra well climbed cunninhams gap with no problem so has power ----am using valvoline 20/50 oil. The handbook says to use SAE oil but not what grade .
intend to flush and change oil -----any suggestions ---can you still buy just SAE 40 we used in motorcycles 50 years back or is everything hi tech
