Amsoil Synthetic oil, the First in Synthetics since 1972

AMSOIL - "Our Company makes the Best Lubricants in the world, period, and challenges anyone or any company to prove us wrong! That won't happen because our competitors know it's true."....... A. J. Amatuzio, President and CEO.

Why is AMSOIL the best synthetic oil in the world?

Amsoil from 1972 has delivered a stellar lubrication product line with the highest level of performance, from wear prevention to fuel mileage savings in a product of vastly longer drain capabilities. Amsoil is proven to be the best oil available on the market by independent laboratory comparison tests.

What this means for you is unheard of convenience, the greatest fuel economy you will ever get from your vehicle and piece of mind knowing the very best lubrication technology is protecting your vehicle beyond other synthetic oils and well beyond petroleum oil.

Do you think that oil is oil so who cares what I use?
Do you buy the cheapest oil you can thinking you're saving money?

Respectfully, know that petroleum oil does not save you money...

yes, it's the cheapest oil to buy, BUT NOT TO OWN

Like anything of quality, the benefits quality
delivers are why we buy quality

Amsoil has for decades compared the performance of their lubricants against the competition by hiring independent labs to performance test oil that the labratory buys off the store shelf.

Other oil companies don't publish their oil performance comparing theirs to the competition, why is that?

Amsoil openly publishes their results, reports such as these are readily available to read;

'Motor Oil Comparison',

'Motorcycle Oil Comparison'

'Gear Oil Comparison'

'Two Stroke Oil Comparison'

'Compressor Oil Comparison'

Magazines tests such as this one doesn't hurt either

Amsoil has never been sued for publishing it's competitor's
oils embarrasing performance results.

This can mean but one thing. The results are true

Producers of regular commodity grade motor oil would like you to think that 'oil is oil' so shop for the cheapest as it's all the same anyway! And they're right actually, regular motor oils do tend to be the same in performance capability except regular grade oil producers leave out the rest of the story! With the information available on this site you will come to know that;

There is a W I D E range of lubrication performance between great and regular commodity grade oil.

Advertising hype is everywhere with everyone claiming to have the best oil there is. This is very confusing on the surface, but you can determine very quickly if your oil of choice is a premium product or like 95% of the rest of the market, a commodity grade product no better than every other commodity grade product.

Here's the question to ponder...
Does the manufacturer of the oil you use now openly compare
their products' performance to their competition?

Is the answer no?... with Amsoil the answer is yes...

Speaks volumes about product performance and confidence in your product to do so don't you think?...

"Lubes' n' Greases" Automotive Editor David McFall, once with the American Petroleum Institute recently tackled the issue of extended drain intervals in his March 2003 column, criticizing the standard 3,000-mile oil change and referring to the American motor oil market as "shackled."

Update, "Lubes' n' Greases" December 2003: Addressing the ethical aspects of keeping drain intervals shortened, David McFall declares, the current stance of the oil industry “comes at a high environmental price.” December 2003 column
