AMSOIL Dealer Offers Discount & Best Synthetic Oil Comparison Testing

Compare Over 600 Synthetic & Petroleum Motor Oils

Most people investigating AMSOIL synthetic oils want to see objective comparisons between AMSOIL and other synthetic oils on the market. Even though AMSOIL's testing is all independently verified and is without challenge from any competing oil companies, there are still those who may not trust the numbers - no sense hiding what we both know to be true.

So, we've published a PDF document that compiles all of the technical specifications for over 600 different oils (AS PROVIDED BY THE OIL MANUFACTURERS THEMSELVES). This data is taken directly from the manufacturers technical data sheets and compiled into an online database by TheMotorOilEvaluator.com.

We are publishing the data here in a 40 page PDF document with permission from TheMotorOilEvaluator.com

Please feel free to download the document and compare the specifications yourself. This is the best, most comprehensive, motor oil comparison testing information you will find anywhere on the net. Just look to the "big red bar" at the top of this page for the link to the comparison document.

AMSOIL Synthetic vs. Mobil 1 EP

Ok, the numbers are in. Mobil 1 STILL doesn't compare to AMSOIL (even with their new EP product). In testing done August of 2005 against 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 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 change interval capability of a motor oil, AMSOIL passed the 500 minute cut-off mark with ease, while Mobil 1 EP came up shy at only 469 minutes. Now, 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 easily have continued longer. Unfortunately, since the test parameters 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 a great deal better protection against wear, 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 EP at your local auto part store.

How Does Mobil Respond?

Well, to be quite frank, they don't. Search for yourself. Search Google. Search the Mobil website. The closest I could find to an official response to AMSOIL's claims was an "Ask Mobil" page on their website. See the following link to see what Mobil said:

Guaranteed Drain Intervals?

Well, if you're using Mobil 1 EP, the answer is not as clear cut as you might think. If you're looking to use Mobil 1 EP for the full 15,000 mile/1 year "guaranteed" drain interval, you may want to take a look at the fine print. Mobil is explicitly clear that their Mobil 1 EP mileage guarantee ONLY covers vehicles that are outside of the vehicle manufacturer's warranty period. Otherwise, if you're still covered by your vehicle warranty, don't expect Mobil to have your back if you choose to extend oil drains with their oil. Not gonna happen. AMSOIL, on the other hand, offers a completely guaranteed 25,000 mile/1 year drain interval that covers you REGARDLESS of whether your vehicle is still under warranty or not. With AMSOIL, you're getting the highest quality oil AND a top-notch guarantee.

Which Will YOU Choose?

So, let's see ... about the same cost, 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. Most 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 "in town at the auto parts chain store" 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 a Brand Name Oil?

First off, although you can find many fairly good quality oils these days, there are those 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 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 down at Jimmy's Auto Parts brings with it a certain amount of familiarity and trust. These oils have a long track record. 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 unmentionables in the creek on a wash board. Then, some "lazy" individual invents 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 no different than the comparison between that washing machine and a wash board. The wash board will do an average 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.
