What do mean by “hard to warm up”?
For Jap car, HTHS no need higher than 2.6 for 0w-20

IMHO.
Simply,  during my 1st cold start in the morning,  the engine will be off as it is sort of like in EV mode. 
There could be lubrication but the engine coolant temp takes almost twice the distance to reach 75°C operating temperature - I use coolant temp as an indication for engine operating temperature. 
Higher HTHS of course higher is better.  🤣

Hybrid...no need to warm up...just move off...no worries..Singapore is not that Cold,the Toyota Hybrid System is tested in Sub Zero Temperature.

IMHO
Within 1km, I need to go over an a-bit-steep flyover. 🤣

There is a balance btw efficiency and protection.

Only turbocharged engine needs > 2.6.

Not many 20ct with HTHS > 2.6

The HTHS is more like good to have. 
Important for me is lubrication and engine to reach operating temperature as fast as possible. 
My Atkinson-cycle engine is a bit nightmarish during movement during cold start.  🤣

Will check it out.  If got Shopee retailer name for SHU 0w-20,  even better. 🤣
The challenge could be unique to me because I drive down MSCP after cold start.  
AFAIK, Atkinson-cycle engine are not design for power at lower RPM.
Thus when the engine kicked in, it will try to go higher RPM which is, well, harsh and noisy.
And a few hundred metres later, I need to climb that abit-steep-flyover. 

I am trying to find information on whether during cold-start, will the oil pump ( electronic? ) works by splashing the engine oil ?

No worries,the Engineers at Toyota already tested this Engine,it is used on Tens of Millions of Toyota Hybrid Worldwide,not to mention,our Comfort Taxis also using it..all clocked over 300,000Km with no or little issue.

If you don't use much,try pumping 98 Petrol,Engine seems like quieter for my Hybrid.

I use lots.  But will experiment with ron98 sometime  in the near future.  I suspect it could be more fuel efficient.

if your oil pump dont work, there will be no lub in your engine.

piang liao lah

 

dont think so much

I also don't want to think too much, but the car is letting me know. 🤣
