Well you are wrong, Joe. I have been using and selling Amsoil for over 26 years, and I know a lot about oil. It was the first full synthetic oil in North America to be approved by the Society of Automotive Engineers for extended changes in automotive use. It mostly exceeds, but always meets the required standards for any application. I use their products in everything from chainsaws (mixed 100 to 1 ) to a backhoe, and I wouldnt use any other oil in all my cars. Just go to the web site and read the literature to find out for your self.
As an example, Amsoil is the only company that produced a fully FAA approved synthetic oil for piston aviation engines. The oil was far superior, in my airplane, to any other oil available by the major companies by a very large margin. I am talking about more power and a 50 degree drop in operating temperature. The only reason Amsoil stopped producing the oil was because of the cost of the insurance. It had nothing to do with the product.
Multi level marketing has good examples and bad examples and I have always felt free to sell the product the way I wanted and I couldn't expect more than that.
Before changing an engine to synthetic oil, the engine should be broken in, ie., the rings should be seated. A person should always use the filters designed for the synthetic oil, because there isn't much point in running a premium oil if you are running crappy filters.
I have successfully switched too many high mileage engines in good condition to count, and all that has to be done is to run an engine flush ( using a clean new filter ) before filling with the new synthetic oil and a fresh high quality filter.
I can tell you that every jet engine today runs on synthetic oil. The formulation is slightly different because the operating parameters are slightly different. They do a spectromatic analysis of the oil approximately every 100 hours ( approximately once a week ), and the oil used by the company worked for would typically remain in the engine until the hot section had to be removed for overhaul. In one engine I am personally familiar with, this was over 24,000 hours.
Synthetic oil is better, you pay more and all your parts last longer.
