I don't care who uses Amsoil, but here are some things that everyone needs to consider before putting Amsoil down:
1)Amsoil stands behind their products for the mileage stated on the bottle and doesn't try to get out of it like Mobil which says "but always follow your manufacturers reccomendations"
2)Amsoil has had very few actual "pay-outs" for the product not standing up to the stack as stated on the bottle. And they do pay out.
3)Amsoil can only recommend an oil for an application and not state that it is API certified because all of them but one is not.
But don't you think that a private company that keeps beating its sales year over year and growing at a very large rate is doing something right?
I mean if they were cooking engines and making false claims the FTC would have closed them down or they would be bankrupt, but they are still here after 30 years, still growing and don't have one FTC complaint on file!
4)An auto manufacturer can't deny warranty because a specific certified/non-certified oil was used, only if that oil failed to lubricate. So if you engine blows up because of a manufacturing defect they can't deny the warranty because you used a non API certified oil only if they prove that it was definitely the oils fault! In which case you would be covered by Amsoil and would receive your payout so long as you didn't abuse the oil in anyway.
If you don't want to use Amsoil or a non API certified motor oil because you aren't comfortable, thats fine. But don't put brands like Amsoil down just because they choose not to certify all their oils (except their XL series), and take this money an reinvest in tweaking their products.
As someone who has used Amsoil for quite a few miles I know there is nothing better both in the way my vehicle feels/performs and the UOA's I have showing it is tough stuff.
Ok... Who's next on the soap box?
