I prefer Penrite oil over any other oil,(engine,diff,gearbox,etc) but have recently changed to Castrol Super RX for the Prado and its as good as any i reckon. Have never tried any other oil in it but, i wanted something that was 15w-40 (Manual recommends 5w-30, which is really only fully synthetic and too thin for the Kimberley temperature) to cope with the temperature and conditions up here.
When chosing oil look for its API rating (i think) and see what car manafacturer recommends, match these two together and get as close to possible with viscosity and ya laughing. Believe me every Toyota dealer uses a different oil so dont think that it matters too much. Look for the letters CI, CJ, CD etc, the lower the letter in the alphabet, (CJ for example) the better the oil. The 2nd letter represents standards for a certain year for which that oil has to exceed. To do with emissions, soot, ability to self clean, etc all in all to make the newer high tec cars run
perfectly. I think the latest is CJ but not absolutely positive.
