We now have the independent lab test data
comparing Amsoil to Mobil 1 SuperSyn

VS

I'm sure you have seen the "nothing outperforms Mobil 1" tag line Mobil uses. Mobil makes a good oil, but as the below tests show, the bottom line is -  Amsoil outperforms Mobil 1.

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. 

Take a look at the following five key tests of an oils performance ability. You will find a description of each test and the important function it serves. AMSOIL 5w-30 synthetic motor oil surpasses Mobil 1 SuperSyn in every test.

Click for larger image	NOACK Volatility The lower the number the better. This test determines the evaporative 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% evaporation loss is allowable to meet the API SL and ILSAC GF-3 specifications. AMSOIL 5W-30 Synthetic Motor Oil lost an extremely low 4.9% of its original weight while Mobil 1 SuperSyn 5W-30 Motor Oil lost 9.17% of its original weight.
Click for larger image	Four Ball Wear The smaller the scar the better. This 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.  AMSOIL 5W-30 Synthetic Motor Oil  produced a wear scar 50% smaller than the Mobil 1 SuperSyn 5W-30 Motor Oil.
Click for larger image	Flash/Fire Point The higher the number the better. This 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. AMSOIL 5W-30 Synthetic Motor Oil has higher flash and fire points than does Mobil 1 SuperSyn 5W-30 Motor Oil.
Click for larger image	Pour Point The lower the number the better. This test determines the lowest point at which a lubricant flows. The lower a lubricants 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 1Supersyn 5W-30 Motor Oil.
Click for larger image	Total Base Number The higher the number the better. Total Base Number (TBN) is the measurement of a lubricants reserve alkalinity. The higher a motor oils TBN, the more effective it is in handling contaminants and reducing the corrosive effects of acids for an extended period of time. AMSOIL 5W-30 Synthetic Motor Oil has a higher TBN than Mobil 1 SuperSyn 5W-30 Motor Oil.

Mobil 1 leaves a wear scar 50% higher than AMSOIL.

Mobil 1 will not recommend or guarantee extended drain intervals.

AMSOIL does guarantee it's 5w-30, 10w-30 and 10w-40 synthetic motor oils for 25,000 miles/1-year before changing.

AMSOIL does guarantee it's Series 2000 0w-30 synthetic motor oil for 35,000 miles/1-year before changing.

Amsoil has continued to grow and prosper competing with large corporations like Mobil, because AMSOIL products have consistently performed better.

Here's a special excerpt from A. J. Amatuzio, President of AMSOIL, regarding AMSOIL and Mobil 1:

"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!"
