They Say Nothing Outperforms Mobil 1?
Wrong! Wrong! 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.
