have used amsoil in motorcycles and still will, but being from the uk originally i am continually surprised at how often oil is changed in north america, for example, mobil 1 in uk is rated for 25000miles, usa 15000miles and canada 15000km's!! i asked a rep at a race meet and he didnt know why the difference, the engine is the same in a bmw for europe as the usa but in europe it wont go for first service for at least 20,000miles, even cheap ecotecs are the same, i can't see a manufacturer risking their motors with such high miles between oil changes while under warranty if it wasnt safe to do so, and euro models usually have a much harder life as most are used with standard trans so they get revved higher and there is more engine braking too, and some of the same climate extremes depending on country etc, i used to run mobil 1 in a jetta tdi with over 400,000 miles on original motor and the oil always looked good still after 10,000 miles!, synthetic definately withstands extreme heat better for sure and will benefit any engine,

So thats 2 full pages of nothing but positive comments about AMSOIL and synthetics. So whos running conventional then? If you use conventional and have never tried synthetics tell me what you've got, meaning: Year, Make, Model and Engine. I'll find what you need and let you know what the cost is. Thanks to everybody who has posted!:thumbsup:

I'd like amsoil a lot more if they ditched the MLM scheme and stopped silencing critics through bribery/sponsorship of online car communities. The vast majority of message boards that have a lot of this amsoil propaganda get sponsorship through amsoil, and any dissenting opinions get censored.

I have no problem with the oil itself. Im sure it's on par with any other average synthetic motor oil, but the amsoil gestapo really turned me off from buying anything from them. Add to that all the fake, cookie cutter corporate "guerilla marketting" tactics they employ and it just leaves a real bad taste in my mouth.

That said there may be a place in my garage for some of that z-rod oil, but that's more because thats a niche that's been underrepresented by the more mainstream oil companies than because I think amsoil is somehow empirically superior to other synthetics.

we are not receiving any "sponsorship" from Amsoil. There are ways to speak a differing opinion without problems and then there are those that cannot. If a guy gets banned it's not because they speak against a sponsor, it's how and what they say.

Differing opinions are fine, we just ask that you keep it respectful and not pure bashing.

Thanks for joining the discussion and I was wondering when someone would bring this up. So why does AMSOIL have dealers? I had the opportunity to have this very question answered by the owner A.J. Amatuzio last year. His response was "If I could only have had 5 minutes with every potential customer to explain the benefits of using AMSOIL. I could help people understand the difference between synthetic and petroleum oils." He realized that wasn't possible so he set out to train and educate those interested in offering a superior technology.

I am sorry you have gotten a bad taste in your mouth about AMSOIL. Like anything there are good dealers and bad dealers.

As for "I'm sure it's on par with any other average synthetic motor oil" Since AMSOIL created the first synthetic motor oil to meet API requirements virtually all other oil company's have came up with their own synthetic oil. That alone does not mean that all those oils are equal. This is confirmed not only with pricing but also on the recommendation of service life for the oil. Not until last year did AMSOIL have a motor oil that was not meant for extended drain intervals.
They released OE that is designed for manufacture recommendation which varies from make to make. Some say 3k and others say much longer.

Thanks again for your post. We had only covered a very small part of AMSOIL as a company so I'm glad you opened up the discussion. I look forward to being an AMSOIL dealer that you can get information from and trust. I am excited to get AMSOIL on your shelf but I'd rather see it protecting what I'm sure you like very much.

Choosing the proper viscosity is more important than choosing a standard or synthetic. Improper viscosity selection will lead to premature bearing and other wear component failures no matter what type of oil is used. This is especially true for cold start and cold operating environments.

I use amsoil ATF and in the race engine and I like it.

Why do most rear end carrier and gear suppliers require the use of a conventional gear oil over synthetic.

Bryce I truely do not have a for sure answer to your question. What I am pretty sure on is that conventional gear oil usually requires additional additives. I can only speak about AMSOIL's lube and say that it's a all in 1 package no additives neccesary. AMSOIL does offer a product you can add to gear oil though!

Diesel truck owners you will want to see this!
 

Here is a study AMSOIL just did for diesel application regarding fuel economy. Very interesting and will save owners lots of $$$. http://www.amsoil.com/performancetests/g3086.pdf

reminded again!
 

Once again i'm reminded why I use AMSOIL in my vehicles.
http://sphotos-b.xx.fbcdn.net/hphoto...45838801_n.jpg Excuse the mess its winter and cold. But this is my wifes 2012 subaru that AMSOIL has not had a filter for so i've been using WIX filters. Changing them every 5 thousand miles. I'm running the oil 15,000 with 3 filter changes. They now have the AMSOIL filter so I will be able to change the filter and oil at 15,000 miles. This saves me time by instead of changing my oil at 5,000, I check it. I use far less oil in a year and one oil filter. This is just better for everybody. If you change your oil more often then that seriously consider trying this.
