Correct, each oil is different. Example is the GC 0w-30 is more of a 5w-30!

However, people in really, really hot climents, don't need a 5w as the tempature never gets to a level where it becomes a factor at startup.

Which is why some people run a 5w-30 in the winter, and then a 10w-30 in the summer!
