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,
outperformed Mobil 1 in all five areas.
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
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,
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.
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,
5W-30 Synthetic Motor Oil has higher flash and
fire points than does Mobil 1 SuperSyn 5W-30
The Pour Point Test determines the lowest
temperature at which a lubricant flows. The
lower a lubricantís pour point, the better
protection it provides in low-temperature
service. As shown in the graph,
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
lubricantís reserve alkalinity. The higher a
motor oilís 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,
5W-30 Synthetic Motor Oil has a higher TBN than
Mobil 1 SuperSyn 5W-30 Motor Oil.
