I've used Amsoil exclusively for about 5 years now and I have been very happy with it. I ran Amsoil 20w50 on the 911 and I run 5w30 on the Mazdaspeed3. We run it in our son's 2002 Ford Focus with 200k miles on it. Heck, I even run it in our lawnmowers and everything else that uses oil.

I use Amsoil 75w90 synthetic gearbox fluid in the Speed3 too.

I am an Amsoil dealer as well, and my old bike a BMW 2004 RT had 104,000 miles on it when I was hit and when the valve covers were off at each service (6K for each service) the internals looked like new. I run it in all my rides and knock on wood have never had a failure or any kind.

I think that if you do your prescribed maintenance and oil changes you should achieve the same results. I can bet that we all know somebody that has never changed their oil or do it when they think about it and never have issues.

A view from the other side........

For the record, I have never used it and I am relatively happy.

I've used it with no problems. Have 2 local parts houses that stock it. But when I'm off working I use Mobil 1. Not going to start an argument here by saying synthetics are better. I just prefer them.:D

Its good oil - nothing fantastic. The use a sound synthetic base oil and a nice add pac from Lubrizol. Back in the day they were pretty darn good but like any company (Lucus, STP, who ever...) they became more about the sale and less about the technology.

One thing is true, their reps are committed (or should be!). I never met a more fanatical bunch in all my life. They do present like a pyramid scheme when it comes down to it.

Bless their hearts!

I have hundreds of thousands of miles on several cars without using a drop of Amway oil.

Yes... It's rule #73.

Though not all of their products are API certified, use of them will not necessarily void your warranty. Federal Law (Magnuson–Moss Warranty Act ) would require the auto manufacturer to either specifically state in the warranty that "use of non API oils will void your warranty" or would require the auto manufacturer to prove that the use of the non-API oil caused a failure that would not have otherwise occurred. Additionally, Amsoil warrants their products and will cover any damage caused by their product.

Do all these amsoil trolls in all the car forums sell ANY oil?

I had one approach me in a gas station while I was filling up the 993. He handed me a catalogue. But their stuff is crazy expensive.

It depends on how much they pimp it. There are Amsoil dealers who do that as their "job". And some of them do quite well at it. I guess if you stick it out long enough, those in the pyramid above you die and your commission percentage goes up. You really only need about two layers below you in the pyramid to be bringing in some steady beer & car money.


I don't push it. If a person wants it, I sell it to them.
I have a few repeat customers, and I sell enough that the commission covers my annual dealer fee. That's about it. I'm on a bottom layer because I have not "recruited" anyone into the cult as my dark apprentices.

My F-I-L was one and several of the family members bought oil from him and when he passed away nobody wanted to do it so I said I would do it. I don't advertise it and only have family and a few friends that buy it.

Whats the matter with swepco oil?
Finn

Motul is stupid hard to find, especially in a 5-40w. I have it in the Boxster, but I had to pay Callas to change it in after a Mobil 1 run. The car was in for other repairs, so that's why I opted to bite it.

When it becomes time, I will find something easier to find.

BTW, Pelican sells Liqui-Moly, Swepco and Redline. I don't know anything about LM.

Liqui-Moly doesn't make 15W50. The choices for me are getting thin. As far as I know it's Redline, Motul and Mobile 1. None of them grown on trees.

Wouldn't the 993 use a 20-50? They make that in a dino. If you're using synthetic, you would't use a 20-50.

No, it's had Mobil 1 15W50 its whole life. I'll only use synthetic. It gets pretty hot here.

Have you done a temp test on how syn 40 (high number) does vs. the 50?

No. All I know is that at 77k miles I'm using about 1 qt. per 2000-2400 miles and I figure that's good enough for me. I have heard of some folks using the Shell Rotella diesel stuff or adding the EOS, but I don't know that I want to mess with what's worked pretty well so far.

Maybe Lubey can shed some light on this. Seems to me that you go down one grade when you designate synthetic. 40w would flow faster, but maybe faster is not better when in comes to oil coolers.

I guess I'm just uninformed about synthetic weights in air cooled motors.

Viscosity is viscosity.
Per the SAE, a 40 weight oil must flow at between 12.5 and 16.3 on the kenematic scale, whether it is dino or synthetic.



Something to think about when comparing oil brands and types:

Group IV (4) and Group V (5) base oil (synthetics) are chemically made from uniform molecules with no paraffin and don't need Viscosity Additives. However, in recent years Group III (3) based oils have been labeled "synthetic" through a legal loophole. These are petroleum based Group II (2) oils that have had the sulfur refined out making them more pure and longer lasting. Group III (3) "synthetic" motor oils must employ Viscosity Additives being petroleum based.

Group V (5) based synthetics are usually not compatible with petroleum or petroleum fuels and have poor seal swell. These are used for air compressors, hydraulics, etc. It's the Group IV (4) PAO based synthetics that make the best motor oils. They are compatible with petroleum based oils and fuels plus they have better seal swell than petroleum.

As more and more large oil companies switched their "synthetic" motor oils to the less expensive/more profitable Group III (3) base stocks it has become much easier to identify which are PAO based true synthetic.

Most, including Castrol Syntec, have switched to the cheaper/more profitable Group III (3) petroleum based "synthetic" motor oil.

AMSOIL Synthetic Motor Oils that are labeled as "100% Synthetic" are PAO based true synthetic motor oils. Unfortunately, even Amsoil has yielded to the rising costs of PAO base stock and those oils which are not labeled as "100% Synthetic" are often either Group III or blends.
