[Shotimes] Oil data chart - additional info

[Donald Mallinson]

Steve,

There is a brand new flyer out from Amsoil that lists the 
latest API comparative testing.

Basically, in all but one test, Amsoil beats all oils in the 
test in all categories: Thin Film Oxygen Uptake, High 
temp/high shear, NOACK Volatility, Pour Point (cold), Total 
Base Number, Cold Crank Simulation, and Four Ball Wear test.

The oils tested were all 10W-30:
Amsoil ATM synthetic
Castrol GTX Drive Hard
Valvoline Synpower synthetic
Mobil Drive Clean
Pennzoil with Purebase
Quaker State Synthetic
Quaker State Peak Perf.
Castol Syntech synthetic
Valvoline
Pennzoil synthetic
Mobil 1 Super Syn multi vehicle synthetic.

(synthetic oils indicated, others are Petroleum based).

The only oil that beat Amsoil in one test was Pennzoil 
synthetic in the cold crank simulator where Pennzoil was 
3538 CCS Viscosity and Amsoil was 3590 (lower number is 
better).  Next best oil was Mobil 1 Super Syn at 3967 with 
the worst at 6458 (plain Valvoline) (over 7000 fails the API 
test)

There was no clear 2nd place winner, and Amsoil beat the 
others clearly in all but that one test.  Pretty impressive.
