Any one of the Amsoil products may be fine. We don't know, because we don't have independent verification (like API certifications) and they refuse to test their so-called better oils according to standard tests. So it is an unknown oil. They can change it any time they like. User history with the old recipe may not carry over to the new recipe.

They test their less expensive oils (so cost of testing isn't an issue) but they advise that those oils won't run manufacturer's recommended change intervals. Lack of confidence in their own product? Or just trying to keep the myths alive? Maybe both.

Why use their fuel system cleaner when Techron is available almost everywhere, and has been tested by the engine manufacturers and recommended by them (even though they don't generally sell it)?

I just get tired of oil companies that spend more on internet marketing than testing. Look at the test results they promote on their website. Shameful. Lots of claims, relying extensively on word of mouth referrals. People who say it is great, without data. And the cycle just continues.

I don't see the same intent to deceive from Snap On or Mac.

Final point: Why are you promoting this product and selling it on this board without having a supporting vendor membership? That is very disrespectful IMO.
