A little history...

I was a diehard Mobil 1 synthetic user for nearly 8 years until I discovered the benefits of Amsoil. One day I attended a car club in St. Louis and and listened in on a conversation between a couple of older car enthusiasts talking about the best oil to use. I was intrigued by their talk of Amsoil. At the time, my engine was having a bad oil consumption problem that a lot of 2001 LS1 engines had during that year for my year car. From what I heard and read, if the problem was bad enough, I would end up bringing the car back to the dealer and have them rebuild the engine under warranty. That was the VERY LAST thing I wanted to do. My engine ran perfect other than the oil consumption of about a quart of oil every 1,500 miles of expensive Mobil 1 5W30 synthetic. I was literally losing sleep over this. So after doing some research, it was determined that the Amsoil Series 2000 0W30 was the best stuff that Amsoil seemed to produce. I've yet to see any oil from any oil competitor out there to show any test rusults to proove that they are better. Because of this, Amsoil proudly put the test results on the back of every bottle they sell. Here's the parts you need to do an oil change on a 2004 Hummer H2. To do an oil change on a 2005 Hummer H2 is basically the same set up. If you change everything to Amsoil, you should get more miles per tank. In my LS1 powered vehicle, I noticed a 3 MPG increase in fuel economy after changing over the engine, transmission and differential to Amsoil. The increase in fuel economy I received in 1 year could buy me nearly 5 Amsoil oil change's worth of oil. If you want the ultimate in filtration, then install a dual bypass filter kit on your Hummer. That thing filters down to 1 micron. Anything above 5 microns causes wear to engine components. With the dual bypass filter, you can virtually eliminate oil changes.

I received a free catalog in the mail, looked it over, found the product ID of TSO to be the oil of choice. I ordered 6 quarts of the TSO and an Amsoil SDF oil filter.

I drove 3,000 miles on this oil while checking the oil stick periodically. To my astonishment, the oil consumption went away. I never thought this could be possible using a quality synthetic oil. I was always told that synthetic oil was thin and that it would go around pistons, etc.

"After seeing the extensive tests using taxi cabs that was performed comparing conventional oil (what the majority of the world uses) vs. Amsoil, you COULD NOT PAY ME to put that conventional oil in any of my cars ever again."

After a year of being an Amsoil customer, I was so happy with the results in my car and other vehicles I and family members owned that I finally decided to become and a dealer for it and now I have this web site to help others.

After break-in on the rear-end differential, I highly recommend Amsoil's 75W90 gear lube. GM recommends that the differential lube is changed after 7,500 miles. You don't need any additives. It keeps gears quite. This is some of the best stuff you can find on the market for rear end differentials. Unlike other differential fluids require the hassle of you changing it frequently, Amsoil's rear-end differential fluid is LOW MAINTENANCE which makes it perfect for Hummer owners as it does not require frequent changes.

I encourage you to study this entire web site and study it well. While you are looking over the site, get a free catalog sent to you in the mail. DO THIS NOW. There's a lot to read. It took me several weeks to read all of this information and absorb it all. I had no idea that this oil was so important. You'll get one heck of an education here. Believe me!

I just can't believe that this oil has been around all of these years and nobody told me about it sooner. I had no idea that tons of NASCAR people used this stuff in their cars and world records were being won as well. It's mindblowing that more high performance automotive shops have never heard of Amsoil and don't stock their shelves with it. From what I heard, there are tons of race car people who swear by this stuff. When it came to protecting my engine and prevent an engine rebuild of my LS1, I would have paid as much as $30 per quart if I had to.
