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
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 pro-vided by the lubricant. As shown
in the graph, AMSOIL 5W-30 Synthetic Motor Oil completed the Four Ball
Wear Test producing a smaller wear
Flash/Fire
Point
The
Flash/Fire Point Test determines the lowest temperatures at which
application of a flame will cause lubricant vapors to ignite (.ash point)
and sustain burning for five seconds (firepoint). Lubricants with higher
flash and fire points exhibit more stable volatility characteristics and
are safer to use
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
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
