Amsoil vs. Mobil 1 SuperSyn |
|
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.
