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.
