Amsoil?

[Samckitt]

A guy I work with is a dealer for Amsoil & he is always pushing the stuff. I have an 03 Silverado 1500HD 4x4. He has tranny fluid, transfer case fluid (both automatic fluid), & differential grease. What is the consesus of this stuff. Is it worth the price difference, is it better?

I use the Racing 20-50 in my track car and am converting almost everything else over to it when the maintenance change intervals come up. It's a good product and what sold me was the metals analysis (parts-per-million) results.

Cheers,

I used it in my boat. I had a 120 Force engine that you had to mix the oil and gas in. 1 quart of their 100-1 ratio would do 24 gallons of gas. I ran it like that for 9 years and never had a problem with it. Traditional oils would blow thick blue smoke and muck up the stern and transom area and just make a mess of everything. The Amsoil would burn a thin white (almost like a light steam) and my stern and transom would stay clean the whole season. From my experience, it's remarkable stuff.

I am also a dealer. I have a 1994 GMC Sonoma with 265K on it, original motor and rear end. Just had the trans rebuilt for the first time. And it's got a custom steel bed on it and carries a 50 gallon tank on the back filled with water and pesticides. Not to mention the 5.5hp Honda motor, 300 yards of hose, the sprayer frame, etc..


Doesn't burn a drop of oil and still has 150 psi in every cylinder. All Amsoil.


Also have a 1994 2500 truck with 234K on it, same deal.



Stuff is amazing. I'll never use any other oil.

My family has been using Amsoil for more than 25 years with no problems. We have put it in alot of different engines from cars to lawnmowers to motorcycles. I personally love using their oil, especially as much as I drive (25,000+ miles a year). Basically, I change oil in my Mustang once a year. Otherwise it would be every 4-6 weeks. I definitely recommend it.

Amsoil was a sponsor on my Cuda. A friend of mine that works for Castroil had recommended them when I discussed oil with him. He said it was an excellent product. When we sucked the oil line shut from the reservoir to the pump, we lost oil pressure at about 180mph. the engine didn't seize or blow..but it was fried..made a believer out of us..

I use it whenever possible. My dad is an Amsoil dealer and he runs it in everything he owns. He has a GMC van with a Chevy 350 motor that has over 300k ORIGINAL miles on it. Of course he is meticulous about maintenance like spark plugs, air filter, etc, as we all should be doing.

So my dad recently took the old van in to a dealer for some small issue and the mechanic commented on how smooth the engine runs. He asked when it was last rebuilt, and was skeptical when my dad told him it NEVER had. He asked my dad how often he changes the oil, and he was in total disbelief when my dad replied, "Every 25,000 miles, religiously." The guy said, "You mean every 2,500?" My dad explained to him that it was indeed every 25 thousand miles, and how it is only necessary to change Amsoil when it becomes contaminated. It really doesn't break down or deteriorate, except under VERY extreme temperatures. my dad runs Amsoil's dual-bypass filter that removes the most microscopic of particles, and he performs oil analysis every so often.

Even with a regular filter, Amsoil recommends oil changes only every 10-12,000 miles, or every 6 months. Truth is, the oil itself will last much longer than 6 months, but most people don't have the ability to analyze it for contaminates that may have come from the engine, so Amsoil is playing it safe.

Amsoil is standard equipment in a lot of high-end European sports cars that see extreme rpm and temperatures. (I used to go to a Porsche dealer to get mine when I lived in San Diego.) Trucking companies have used (and reused) it for very high mileage uses for a looong time. "Synthetic" is all the buzzword around engine oils these days, and while all synthetics are far better than regular oils, most of the companies making them are relative newbies. Amsoil has been refining their synthetics for 30 years, they are already well-established and have nothing to prove, therefore you won't find them at your local parts store. (They prefer to keep the cost down on as much as possible on an already expensive process by distributing their product through a nation-wide network of local dealers--you can usually find one in the yellow pages.) The price is actually amazingly low when you consider what a perfect product it is. They are in a league so far above all the others, that most people don't comprehend the difference. If you have a high-dollar engine that sees serious duty and you to protect it to the max, and you do your homework, it's an obvious choice.

Its good stuff, but I hate network marketing (think amway).

You can pay them $20/yr and order directly from them and avoid the network marketing scams.

I have used it in my bike, my wifes truck, and my car. Don't have any testimonials on how long my engines have run with it, but will say that it made my bike shift smoother and easier once I put it in the primary and trans.

I used it in my two stroke aircraft engines with great success for years. Highly recommended.

I do mobile detailing out of my 2004 Sierra 1500. I put about 25,000 miles a year on a truck.
I also have a 6x8 utility trailer with a honda generator and power sprayer on it. Both of these have an automatic low oil shutoff. They will run even when the oil levels are low.

Like everyone else says, it's as good as gold, really.

Interesting. Where can you buy those filters? My truck just turned 100K a few days ago and it got a fresh installment of Amsoil. But I used a regular Fram oil filter.

my teacher at school is a dealer and a friend and myself are also dealers and i think the stuff works great.

however, at least here, you can buy Amsoil at NAPA. they may not carry the full line of products (i went to see if they had an Amsoil filter for a friend's camaro and they didn't have any filters in stock), but they can usually get them within a day or two - at least that's what the guy told me.
