Then there are others ranging from adequate to down right dangerous to the engine or equipment it's being used in. If you have a machine that you use any old oil, used oil, or the cheapest you can find then you probably won't be interested in anything else I have to say
I won't criticize any other brand to make AMSOIL look good, but if an inferior product doesn't meet minimal standards and is in fact engaging in fraud by claiming something they aren't, then I feel they are fair game and should be exposed.
I ran across an interesting website dedicated to informing the public on the sensitive subject of automobile motor oils. As far as I could tell they show no bias or favoritism toward anyone. It is: wwwpqiamerica.com, stands for Petroleum Quality Institute of America. The site rates oils and oil manufacturers from good, meeting industry standards, to down right junk in an unbiased pull no punches way. I found the site quite refreshing in this day and age of BS advertising. I was surprised to see brands I'd never heard of and some of the "TRASH" being sold to the unsuspecting public.
Check it out and see how well your favorite stacks-up.
Speaking of quality, my association with AMSOIL has been virtually nothing but a quality relationship and a positive influence on my life. Sure there have been times when issues happened; the website gave me trouble, or this or that system wasn't working quite right, or my order was messed up. For me though, it boils down to – the overriding attitude from company personnel, quality of the products, ethical business practices, and dedication to Dealers and customers. It is far above what I observe in everyday life. If they say something will do xyz, you can bet it will meet or in most cases exceed the claim or standard. I've seen AMSOIL products go beyond expectations to many times to recall. AMSOIL is dedicated to me, as I to them and the "VERY HIGH" quality products they produce. I thank God every day for the ability to pass on information about these great products and this extraordinary company.
