AMSOIL Synthetic vs. Mobil 1 EP


Ok, the numbers are in. Mobil 1 STILL falls far short of 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 champion, even over the new and "amaaaaazing" Mobil 1 Extended Performance oil. You can see the account 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 drain interval capability of an oil, AMSOIL passed the 500 minute cut-off mark with ease, while Mobil 1 Extended Performance 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 comfortably have continued longer. However, 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 of minor consequence. AMSOIL offers significantly better protection against component wear, better cold temperature performance, less high temperature evaporation and longer guaranteed drain intervals. Moreover, at Preferred Customer pricing, you'll pay virtually the same amount for AMSOIL (including shipping) than you'll pay for Mobil 1 EP in town at the auto parts chain store.

So, let's see ... similar pricing, enhanced protection against wear, 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!!!

Listen, I've got nothing against Mobil 1. It's an excellent oil - especially the new Extended Performance Product. But, if you're going to pay that kind of money for an AMSOIL oil (Mobil 1 is typically more expensive than most other "down at Jimmy's Auto Parts" brands), why not get the best your money can buy? You'll never go wrong choosing AMSOIL, and we've got the test results to prove it.

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


First off, even though there are a considerable number of decent oils on store shelves these days, there are quite a number of companies whose integrity should be looked upon as somewhat questionable. 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, selecting a well known name brand that you can get off the shelf brings with it a certain amount of familiarity and trust. These oils have been around for years. Our fathers and grandfathers have used them for years. Why switch? If it aint broke don't fix it, right?

Well, I guess it all depends upon your outlook. For years people washed their clothes in the creek on a wash board. Then, here comes the washing machine. 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 like the comparison between that washing machine and a wash board. The wash board will do an fair 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.
