Hey guys, this may be answered, but......
Let's say we are comparing both EO are the same.
Which viscosity would you go for with our 1Malaysia climate? 5w30 or 0w40?
xw30 (be it 5W, 10W, etc) should be thinner than the 0w40, right?
as low as possible specified by your engine manufacturer specifications.
personally i will got -10 viscosity over manufacturer specifications.
in other words, as hot as our Malaysian weather is, we don't have constant 40 Celsius ambient temperatures which warrants thicker viscosity.
and yes xw30 is thinner than xw40.
i run 0w20 on my inspira and 0w30 on my iswara/kancil/sentra
for further information, please spend time reading the information on first page.
