No it isn't. Look at the Pour Point and Cold Cranking numbers. None better. Pick the 0w-XX and all will be well. AMSOIL is VERY popular in cold climates.
Tim, lets look at some numbers of Redline 0W-20 versus Amsoil 0W-20
Pour Point for Amsoil 0W-20 is -65 Degrees Fahrenheit or -54 Degrees Celcius
Pour Point for Redline 0W-20 is -76 Degrees Fahrenheit or -60 Degrees Celcius
Lets look at some 40 Degree Celcius Numbers which is about 100 degrees Fahrenheit
Amsoil 0W-20 has a 40 Degree Celcius Number of 49.1
Redline 0W-20 has a 40 Degree Celcius Number of 43
What are these numbers telling me, since most of the wear in an engine is during the 1st 20 minutes of driving or maybe until the car is fully warmed up, since Redline 0W-20 has a lower Pour Point it will flow faster on startup, and during the warm up cycle since it has a lower 40 Degree Celcius Number it will flow faster and lubricate the parts in my engine quicker than Amsoil 0W-20
Tim, the Wear Statement I made, came from Gary Allan who is an Amsoil Salesman like yourself.
I almost forgot to mention the HTHS Number, that's High Temperature High Shear.
Amsoil 0W-20 has a HTHS Number of 2.8
Redline 0W-20 has a HTHS Number of 2.7
