I think the Australian market might have been a little conservative about 20 years ago

1998 - 2002 Honda Accord J30A1 USDM -Export

5W-50 -40 to 0C
10W-50 -20C to 30C
25W-50 0C to 40C

Conventional 6000 km maximum
Synthetic 12000 km maximum

The chart doesn't go there but I'm guessing you would need a 60 grade for over 40C.
 
Penrite's chart for our '05 CRV specifications in Australia show similar grades.

They also show 5w-30 for the engine in our '22 MDX.

Up to 0°C? Appears to be a typo, makes no sense at all except for vehicles
specced for 10W-60 (older BMW M cars) and even that seems overly wary.
.

10W minimum above 0.
15W minimum above 30C.

I'm assuming the concern about the winter rating was because of potential for shearing. I think they may have offered some wide spread conventionals there that we didn't see.

Somehow I doubt they are that sophisticated, but even if they are then I'd say it was deposit formation not viscosity loss.

Possibly. I know it used to be common in the USA for manufacturer's to only allow 5W-30 to 30C. 10W-30 was required above that. I assumed the reason was VII shearing.

The only manufacturer that I've ever seen give a reason for avoiding wide-range multi-viscosity oils was GM and the that was because of piston ring sticking.

Consensus here in the early days was to use 10W-30 Conventional or 5W-30 Synthetic. I suspect with modern "Conventional" Group II/III Blend it's obsolete advice today.
