They Say Nothing
Outperforms Mobil 1? Wrong!
 AMSOIL INC. set out to examine the specifics of the
overly broad "Nothing Outperforms..." Mobil claim. AMSOIL 5W-30
Synthetic Motor Oil (ASL) and Mobil 1 SuperSyn 5W-30 Motor Oil were
analyzed 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 below, AMSOIL outperformed
Mobil 1 in all five areas.

 NOACK Volatility
The NOACK Volatility Test determines the evaporation loss of lubricants
in high-temperature service. The more motor oils vaporize, the thicker
and heavier they become, contributing to poor circulation, reduced
fuel economy, increased oil consumption and excessive wear and emissions.
A maximum of 15 percent evaporation loss is allowable to meet the
API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL
5W-30 Synthetic Motor Oil lost an extremely low 4.9 percent of its
original weight during high-temperature service, maintaining its
superior protective and performance qualities,while Mobil 1 SuperSyn
5W-30 Motor Oil lost 9.17 percent of its original weight. |
 Four Ball Wear
The Four Ball Wear Test determines the wear protection properties
of a lubricant by measuring the wear scars produced by four metal
balls in sliding contact under the test parameters. The smaller
the average wear scar, the better the wear protection provided by
the lubricant. As shown in the graph, AMSOIL 5W-30 Synthetic Motor
Oil completed the Four Ball Wear Test producing a smaller wear scar
than the Mobil 1 SuperSyn 5W-30 Motor Oil. |
 Flash/Fire Point
The Flash/Fire Point Test determines the lowest temperatures at
which application of a flame will cause lubricant vapors to ignite
(flash point) and sustain burning for five seconds (fire point).
Lubricants with higher flash and fire points exhibit more stable
volatility characteristics and are safer to use and transport. As
shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil has higher
flash and fire points than does Mobil 1 SuperSyn 5W-30 Motor Oil. |
 Pour Point
The Pour Point Test determines the lowest temperature at which a
lubricant flows.The lower a lubricant's pour point,the better protection
it provides in low-temperature service.As shown in the graph, AMSOIL
5W-30 Synthetic Motor Oil has a lower pour point than Mobil 1 SuperSyn
5W-30 Motor Oil. |
 Total Base Number
Total Base Number (TBN) is the measurement of a lubricant's reserve
alkalinity. The higher a motor oil's TBN, the more effective it
is in handling contaminants and reducing the corrosive effects of
acids for an extended period of time. As shown in the graph, AMSOIL
5W-30 Synthetic Motor Oil has a higher TBN than Mobil 1 SuperSyn
5W-30 Motor Oil. |
