ok la.. this is what the correct one.. 
the thicker oil are not protecting ur engine.. it just how to solve the problem.
valve seal problem, oil decreasing too much, tappet issues and etc..
low cc engine normally like viva used w30.. either 10w30 or 5w30.. BUT not 0w30
the low the xW number , the oil is very thin.. thats mean.. DO NOT USED 0w30 on VIVA... no one in malaysia used 0w30 on their viva..
high cc engine better used 40,50 or 60 - because the engine generate more heat during running.. the number mean the engine oil operating temperature.
0w,5w,10w,15w,20w is as what u explained above but it also tell the level of the oil it selves.
if u using 0w50,0w20 on the normal and low cc engine (except hybrid car), ur car will KO faster.. aircond also sometimes cold and not (because engine also drive the aircond), more leaks.. head leaks, white smoke, SLUGGISH and etc..
ok this example ;
20w50 - for old car.. > 10years which is have white smoke (valve seal ) problem
10w30 - for low cc engine (kenari/kelisa/viva) but this car also can used 5w30..
10w40 - recommended for car > 5 years but it also can be used on new car, also can be used on old car if the user maintain to used it.
5w30 - recommended for new car
5w40 - recommended for new car which prefer performance
0w20 - hybrid car
0w50 - high performance car, new engine,good maintenance...
HOW do you know that there's no people using 0w30 on VIVA? DO you do a statistics YOURSELF? HOW do you know that using 0w30 on normal and low cc engine will make the car KO faster? or it's just based on your own assumption? the thicker oil are not protecting ur engine.. it just how to solve the problem.

Like what the rest of the people here know that the W stands for winter and makes no differences in our hot climate. If you say that the lower the winter number, the thinner the oil goes, WHO DOESN'T KNOW that? does it matter when the engine has reach optimum temperature?
You work in PROTON doesn't mean you know everything and please stop saying other people STUPID whereas you're the one who we're laughing at.
