Mobil 1 Extended Performance vs. AMSOIL

Ok, the numbers are in. Mobil 1 STILL can't match AMSOIL (even with their new EP 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 synthetic motor oil. You can see the specifics 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 change interval capability of a motor oil, AMSOIL passed the 500 minute cut-off mark with no problem at all, while Mobil 1 Extended Performance fell just a bit shy 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 certainly have continued longer. Nevertheless, since the test specifications limit the test run time to 500 minutes, we were cut short of establishing just exactly how far the oil could really go.

Either way, it is of minor consequence. AMSOIL offers significantly better wear protection, better cold temperature starting, 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 Extended Performance down at Jimmy's Auto Parts.

So, let's see ... same price, 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'd like the Mobil 1 ---- Yeah Right!!!

Don't get me wrong. I'm not trying to bash Mobil 1. Many people use it and swear by it. It's a good product. But, it's also a commodity product. Only so much quality can be built into a product that has to sell "off the shelf" next to lesser priced synthetics - especially when so much money is also being funneled into big name NASCAR sponsorships and ad campaigns. Go with the best. Choose AMSOIL!

Why AMSOIL & Not Pennzoil, Valvoline, Mobil 1...?

First off, although there are a number of good oils on the market today, there are at least a few companies whose integrity should be looked upon as a bit 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 oil 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 at your local auto part store brings with it a certain amount of familiarity and trust. These oils have been around 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 point of view. For years people washed their shirts and pants in the river on a wash board. Then, some "lazy" individual invents the washing machine. Why switch? That wash board has been working well 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 similar to the comparison between that washing machine and a wash board. The wash board will do an acceptable 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.
