Not all 5w30s are created equal!

I'll start by giving a quick primer of oil viscosity. Let's take 5w30 for example.

The W stands for Winter. It does not stand for "weight." So 5w is determined by the oil's performance during a set of tests by the SAE J300 standards. A very long time ago, it meant that oil could be pumped as well as a SAE 5 oil at those temps, but now it's a bit more sophisticated. Just know that those tests are done at very cold subzero temps like neg25C and even colder!

The second number (30 in this case) is a range of viscosities measured at operating temp (100C). Viscosity is usually measured in cSt (centistrokes). The 30 specifies a range of these. So there are "thick" and "thin" 30s.

Now, back to the topic on hand. Viscosity works on a curve. Just because two oils have similar (remember, they just have to pass the test, some exceed the test by a lot!) viscosities at one temperature doesn't mean they'll be the same at all temperatures.

Here's a great chart showing the difference. According to the most up-to-date specs on the manufacturer's websites (12/08) here's how they stack up. I took two of AMSOIL's greatest competitors and a one conventional oil to illustrate the viscosity differences in the cold!

How did the AMSOIL ASL 5w30 perform? Rather well I think. Mobil1 EP stayed close, but as the temperature dropped, the performance gap widened. Pennzoil Platinum faired well, but nothing compared to the AMSOIL ASL 5w30. What about the Valvoline All Climate? It was the token conventional oil in the test, and like the old saying goes, "Don't bring a knife to a thermonuclear warhead fight."

I don't know about your climate, but here in the midwest it does get cold! Even when it's not subzero, the AMSOIL ASL 5w30 still had a better viscosity thanks to it's superior viscosity index.

Special thanks to the viscosity charter found here.
