AMSOIL is Best Synthetic Motor Oil: Comparison Testing

AMSOIL Synthetic Oil vs. Mobil 1

Ok, the numbers are in. Mobil 1 STILL can't match AMSOIL (even with their new Extended Performance product). In testing done August of 2005 vs. 10 brand name petroleum and synthetic oils, AMSOIL came out the clear victor, even over the new and "amaaaaazing" Mobil 1 Extended Performance oil. You can see the information for yourself in a moment, but here are some highlights:

• Mobil 1 EP Evaporates 38% Faster Than AMSOIL
• Mobil 1 EP Allows 18% More Cold Start Friction
• Mobil 1 EP Allows 22% MORE Wear

In addition, on the TFOUT test, the "Thin Film Oxygen Uptake Test" (ASTM D-4742), which provides a very good correlation to the long drain capability of an oil, AMSOIL passed the 500 minute cut-off mark with flying colors, while Mobil 1 EP missed the mark at only 469 minutes. Of course, 469 minutes is significantly better than most of the competing oils, so you've got to give Mobil some credit. But, the AMSOIL product could absolutely have continued longer. Unfortunately, since the test specifications limit the test run time to 500 minutes, we were cut short of seeing just exactly how far the AMSOIL synthetic motor oil could really go.

Either way, it is irrelevant. AMSOIL offers considerably better protection against wear, better cold temperature performance, less high temperature evaporation and longer guaranteed drain intervals. Moreover, at Preferred Customer pricing, you'll pay roughly the same price for AMSOIL (including shipping) than you'll pay for Mobil 1 Extended Performance at your local auto part store.

So, let's see ... about the same cost, enhanced wear protection, easier cold starts, less evaporation, longer drain intervals. Boy, that's a tough one ... I'll have to think about that for a little while. I think I'll take the Mobil 1 ----------------- not!!!

Don't take my word for it. Spend some time browsing our website. It won't take long to recognize that AMSOIL offers the world's best oils, and we've got the specs and test data to prove it.

Why Wouldn't I Choose a Name Brand Oil Over AMSOIL?

First off, although there are a number of good oils on the market today, there are quite a number of companies whose integrity should be looked upon as tainted at best. Specifically, when companies such as Valvoline and Quaker State (Quaker State is the manufacturer of Slick 50 Engine Treatment) utilize such deceptive advertising in regards to their additive products, how much weight can you put on advertisements for their motor oils?

Of course, using a brand that is well known and that you can get in town at the auto parts chain store brings with it a certain amount of familiarity and trust. These oils are ones that people have been buying for years. Our dads and grand-dads have used them for years. Why switch? If it aint broke don't fix it, right?

Well, I guess it all depends upon your perspective. For years people washed their clothes in the river on a wash board. Then the washing machine was introduced. Why switch? That wash board has been providing clean clothes for years. Your parents used it, your grandparents used it. It's been in the family for decades and has served you well. Is it really worth switching?

I say it is, and I also say that the comparison between AMSOIL and other oils is very much akin to the comparison between that washing machine and a wash board. The wash board will do an adequate job of washing clothes, but it can in no way compare with the clothes washing ability of the modern washing machine.

AMSOIL offers the absolute BEST protection for your vehicles and equipment.
