Engine Oil

[Kracka]

LOL @ everyone claiming they have billion times more wear protection. Marketing hype at it's finest. The 3/4 ball wear tests mean nothing, it's a test that was designed for testing gear oil, not engine oil.

(sorry in advance for the goofy formatting, I bolded M1 numbers to make it a bit easier to read)

Mobil 1 10W-30 Amsoil XL 10W-30
Viscosity @ 100ºC: 10.7 10.5
Viscosity, @ 40ºC: 65.3 63.6
Viscosity Index: 154 155
HTHS Viscosity: 3.26 3.2
Pour Point, ºC: -39 -40
Flash Point, ºC: 230 232

When you compare these actual technical specs (i.e. not laboratory tests paid for by Amsoil) you can see how nearly identical these oils are.
