Is 10W-30 Syn Oil Obsolete

Don't know what you're talking about - I belive 10W-30 is THE no. 1 consumer grade in NA.
10W-30 syns are good, b/c they often don't need VII's to make the spread, and can actually more often than not, pump and flow as well as a 5W-30 synthetic - the numbers for two are often VERY close...

10W-30 synthetic = popular AND good
Sounds like we have a winner!

Last article I read(this year)from a trade publication still had 10W-30 the number one selling oil.
I heard the same reports and believe 10w30 is the most popular grade overall.
10W-30 synthetics are really good oils in that they require little VII to be multigrade, so they do not tend to shear down as much and are less volatile.
In most climates above 0F (-18 C) 10W-30 will perform adequately, and in high temperature engines and conditions I would imagine it holds up somewhat better than 5W-30 for staying in grade and not thinning as much at high temperatures. Typically they offer an HT/HS viscosity closer to 3.3 than the 3.0 of 5W-30, and stay in grade.

North America encompasses everything from +50C temperatures in the Sonora Desert to -50C temperatures in Alaska and northern Canada, 10W-30 is a good choice for anything over about -20C but in this area anyway the local Quick Lube place tells me they use 5W-30 and 5W-20 the most with requests for 10W-30 only during the summer.

That's gotta be it right there.

10w30 is my winter use oil in one vehicle (15w50 during the summer) and 10w30 year round in two other vehicles.
