AMSOIL versus Mobil 1 Comparison Shows AMSOIL Is Better

A Message from Al Amatuzio, President and Founder of AMSOIL

Mobil 1 was introduced after AMSOIL had paved the way for synthetic motor
oils back in the '70s. When it was introduced, it caused great concern among
many of our Dealers. But in my President's Message at the time, I assured
everyone that having Mobil 1 on the market would only help us sell more oil.
Mobil confirmed everything we had been saying about synthetic oils, and our
products and claims instantly became more credible. Since then, we have always
been compared to Mobil 1. When people think of synthetic motor oil, they think
of AMSOIL and Mobil 1, not the other Johnny-come-latelys that have come on
the market more recently. I have always said that Mobil 1 is a good motor oil,
because compared to the run-of-the-mill motor oils on the market, it is. I have
also always said that AMSOIL motor oil is better, again, because it is. Mobil
makes their oils to run at normal drain intervals while we make ours for
extended drain intervals, and therein lies the difference. Their oils don't have
to be as good as ours, so they are not. To prove that point, we ran a number of
comparative tests on our 5W-30 (ASL) and Mobil 1 Super Syn 5W-30. The
test results confirm what I have said all along, "AMSOIL makes better motor
oil." These test results show significant differences between our oils. Look at
the results of the NOACK Volatility Test. Which oil is going to last longer in
service? Look at the difference in total base numbers. Again, which oil is going
to provide the longest lasting protection? Look at the Four Ball Wear Test.
Which oil will protect against engine wear better? In every category we
tested, AMSOIL proved superior. Lower pour point, higher flash and fire
points, AMSOIL tested best. So when I hear the claims that nothing
outperforms Mobil 1, I have to say, "WRONG!" They may have good slogans
and marketing hype, but when it comes to superior performance, I say nothing
beats AMSOIL! Once again, you always get more value when you buy AMSOIL
lubricants. These and many other tests prove it!

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.

The Four Ball Wear Test
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.
