AMSOIL - "Our Company makes the Best Synthetic Lubricants in the
world, period, and challenge anyone or any company to prove us wrong! That
won't happen because our competitors know it's true."
Here is a quote from A.J. Amaturio, President of AMSOIL,
as written in the monthly AMSOIL Action News regarding AMSOIL and Mobil 1.
Test results below.
"As most of you are aware. Mobil 1 was
introduced after AMSOIL had paved the way for synthetic motor oils back
in the '70's. When it was introduced it cased great concern among
many of our Dealers. But in my Presidents 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-lately's 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
and Mobil 1 SuperSyn 5W-30. The test results are published in this
Action News, and they confirm what I have been saying all along.
AMSOIL makes a better motor oil.
These test results show significant differences between the oils.
Look at the results of the NOACK Volatility Test. Which synthetic
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 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!"
A. J. Amatuzio, CEO AMSOIL President
To determine which oil is best, 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.
Mobil will not recommend or guarantee 25,000
mile/1-year drain intervals like AMSOIL 5W-30, 10W-30 or 10W-40 or
35,000 mile/1-year drain intervals like AMSOIL 0W-30 Severe Service
Synthetic does and that is a fact. No-where on the Mobil bottle does it
state 25,000 miles/1-year or 35,000 miles/1-year.
Mobil 1 has run the tag line for their advertising
stating "nothing outperforms Mobil 1". Mobil makes a good oil, but
I'm here to tell you that it does not outperform AMSOIL Synthetic Oils.
They can come out with all the catchy advertising buzz words to market
their oils, but in the final analysis, buzz words don't add one thing to
their product's performance. The only reason AMSOIL has continued
to grow and prosper competing with large corporations like Mobil is that
AMSOIL products have consistently performed better.
