AMSOIL vs. Mobil 1:
AMSOIL set out to examine the specifics of the overly broad
"Nothing Outperforms..." Mobil 1 claim. AMSOIL 5W-30 Synthetic
Motor Oil (ASL) and Mobil 1 SuperSyn 5W-30 Motor Oil were
analyed in five key bench tests measuring motor oil performance:
NOACK volatility, flash/fire point, pour point, four ball wear
and total base number (TBN). As Shown in the charts from the
AMSOIL outperformed Mobil 1 in ALL FIVE areas!
AMSOIL vs. Royal Purple Motor Oil:
Protection Against Wear - The Most
Critical Component in oil protection!
The Four-Ball Wear Test (ASTM D-4172)
evaluates the protection provided by
engine oil under conditions of pressure
and sliding motion. The size of the scar
left as a result of the test determines
the amount of wear protection the
the wear scar, the better the protection.
The ASTM-D4172 test
results (see link below) reveals that Royal
Purple 5W30, 5W20 & 20W50 causes nearly 3 times
the wear scar when compared to AMSOIL.
Now let's see what is behind Royal Purple
Formulation & how the technology compares with
AMSOIL, which has half the wear scar as Royal
