Difference between oil weight Options

[hs2g]

I was wondering what the differences are in the oil weight. Like 10w40, 10w30, 5w30 you get the picture. What do these numbers represent? And since I live in minnesota I hear running a lower weight is better durring the winter season?

BTW what oils does everyone use? I would use synthetic buy they are too pricey for me, so i'm using Valvoline Maxlife.

Well the different weights work better for different temperatures... Heat makes oil less viscous... so in hot wheather u use heqavier weight oils so they heat up more and become thin enough to run through the whole engine and lubricate better. In colder climates you use oil with less weight because they dont heat up as much as in engines running during summer etc so the less wieght ensures it heats up and becomes just as viscous as heavier hot oil... 40 or 50 weight is normally good for hot climates
like texas and some states during the summer
but normally 30 or 40 weight is average
u would use 20 weight in winter
maybe even 15 weight. All the information is online for you to find. Just use google.
