Amsoil

bigfig · Oct 17, 2004

I was wondering...my neighbor brags on Amsoil Syn. all the time. I have used it and it is expensive. I was wondering if there was some rating system for determining which synthetic is of a higher quality than other synthetics? Someone on the board mentioned a group 3, 4 and 5.Is there a website somewhere that gives the ratings of synthetics or does someone know what other synthetic would be on the same par as Amsoil or is there one better than Amsoil? My neighbor puts Amsoil in his vehicles then he tries to run them 30k or 40K miles just changing filters, which seems dumb to me because a filter can't get out a lot of those oil pollutants. Then again I have a friend who only buys recycled oil (real cheap skate). I'm wondering how they get all that black stuff out of the oil to make it new again. Wish I had a filter that could do that.
Any helpful comments appreciated.

In short, go here http://www.bobistheoilguy.com/ for everything you'd ever want to know on oils and grease and more. That is the premier website for oils. It also gives you links as to where you can have your oil tested to be sure.

Another place is http://www.caranddriver.com/article.asp?section_id=27&article_id=3631&page_number=1
which sheds some light on the synthetic differences that currently exist because of loop holes and less than ethical marketing.

I know that when the naval fleets are at sea that they do not dump used oil. They reclean it and it comes out looking just like new.

I have used many types of synthetics: Mobil 1, Castrol Syntec, among others. I now use Amsoil in everything and won't be switching. It isn't much more expensive than any of the others, except that I need to have it shipped.
They have a new Series 3000 5W-30 diesel oil that is in my B2410 for the winter.

Is Amsoil an Amway product ? If so who makes it ?

Gee, never heard that before. But no, they are not the same. Not even close.......

They make there own oil but buy there basestocks (PAO) from the top suppliers in the world. Additives come from Lubrizol.

There XL series come from Petro-Canada I think.

True, I believe a group 3 can be called synthetic when it should not be. Only Grps 4 and 5 are true synthetics.

Try this like, it explains a little about what the oil cleaners do.

Maybe your friend also has the AMSoil bypass filter system which would filter to a much lower level than the standard full flow filter.

Was just curious because of the names being similiar and some references to the way Amsoil was marketed. I have not used Amsoil because of not seeing it for sale locally and the price. Most say it is good stuff though.

No, he just uses a spin on filter on the engine block and pushes it 20-30K miles on Amsoil. He's TOTALLY convinced he doesn't have to worry at all. I, on the other hand, think he has lost a few marbles. It may be good engine oil, but engine oil still gets polluted by contaminants and that is the whole purpose of changing it.
