Oem's specify a lubricant that will be easily attainable and provide adequate engine life.
Clevy, so Toyota are capable of bringing an entire car into Australia but can't ship a lubricant to the country ?
That doesn't ring true, as a couple of cases in the trunk of each car shipped would easily last out the warranty period.
Where they may not be wanting to go there is that you could never convince an Aussie that 1qt/800 miles is acceptable oil consumption. GM had that problem with the V-6, emptying the sump between 10,000km OCIs...it hurt their credibility badly.

"Adequate" engine life isn't an argument that points to a pile of failed engines...have never said that it did/would, and I don't think too many have (unlike the pile of failed engines next to the racetrack on 50s).
Honda use the terms like "improved fuel economy while still providing adequate/acceptable life"...they are inferring that there's more durable ways of doing it, but this is "OK"...it's probably more than OK, as there's no point having another 200,000 miles in an engine when the car is scrapped...it's utilising resources more efficiently to use 1-2% less fuel over the life of the vehicle.
Food for thought, I've mentioned it before. With all the words in the English language why is it when you look at literature like the owners manual or you see written material about 20 grade oils they use words like "adequate and acceptable" when they refer to the protection provided by 20 grade oil. I mean we have words like "best, better, superior", why aren't they used? Probably because those words aren't the truth.
EG: If you went up to school on open school night and little Johnny's teacher said, Johnny's work is "adequate", or Johnny's work is "superior" compared to the other students which would you rather hear?
I see we're thinking along the same lines.
