"Americans who have not been do not know what hot is. It is not Florida summer hot. It is not Bahamas hot. It is very very very hot. In this weather a 15w40 is your minimum oil viscosity."

Hmmmm. As a transplanted Californian who lived in Pampanga (elevation approx 500ft. MSL) for five years, I disagree. Some people might even say "bs"

. It's humid and quite warm much of the time at the lower elevations, but not Arizona or Colorado river, CA hot. Climatologists might describe it as the moist tropics. Folks from the gulf states and Florida would be right at home. Yes indeed, stop and go driving is the name of the game. No need for any special oil, but if you got plenty of $$$, synthetics would be luxurious. My $0.02

The owner's manuals on both cars offered “thick” oils as options, providing they are used within their proper temperature ranges. If heavy weights fry pumps, why would auto manufactures even suggest that they are an option?

There are cold cranking specs that state when its too cold to use a particular oil, because it can't be pumped. If you stay within those recommendations, your oil pump will be fine.
 
The nonsense about not using 15w40 in a small engines is just that, nonsense.

For years 15w40 was the RECOMMENDED oil by Volvo for it's 4, 5 and 6 cylinder engines in operating conditions of 40 deg. F and higher. My 9 HP John Deere even lists 15w40 as a recommended summer oil.

Heavy duty fleet motor oils are an excellent low cost choice for tropical climates. Any engine which can run on 5w30 at 3 AM in Canadian in the winter is not going to have any problem pumping 15w40 in the tropics.

I owned a Toyota w/ a 4 cyl 22R engine 20 years ago. I used 10/40 oil in it and it ran fine but consumed 10/30. 10/40 year around. 100 deg summers and 30 deg winters.
