I reckon it sounds like that oil would be too heavy.The Castrol website recommends 15W 40.

Hi Middy,
I use the Penrite 20/60 when I am towing the caravan in hot conditions in Central Australia and the NT. I have a Landcruiser 80 with aftermarket turbo 360K on the clock.
With the clearances I have with wear over 360K I reckon it works well. Any other time I use the Penrite 15/50.

i picked up some penrite oil at a good price once

got home and noticed it was 20/60 rather than my normal 15/40

Ah well i thought its only for 500km what could possibly go wrong?

shortly after the rear main started leaking, it improved after cvhanging the oil but still weeps. i blame the thicker viscososty for adding pressure blowing through the seal

Thick oils take too long to get around after you start up and will increase your fuel consumption. Better to use the thinnest oil that's recommended for your motor. The guy at Repco is wrong.

What qualifications does the Repco man have in relation to oils.
He might sell oil (salesman) but have no depth of knowledge about oil and its uses.
Phil G mentioned startup time when oil isn't getting to the engine parts and especially the turbo which does have its little sump supply for startup but relies on a good quick flow to lube and cool. The turbo spins thousands of times before the oil gets to the turbo, I wouldn't like to prolong this spinning with little oil aspect.
A 2.7 Terrano shouldn't be worn out at 190,000km and should use the recommended grade oil. Terranos last real good, don't put it at risk by using a heavier oil on the recommendation of who????????
