It is just how they start their manufacturing process and has little bearing on how they actually perform. Also, many oil companies will not publicly disclose their API test results. So how does Amsoil get the numbers on their website? That is a good question because it isn't from the ANSI created API required tests, I checked with every company. The only company willing to give almost all test data was Valvoline (I wonder what everyone else is trying to hide). Last, you really can't believe what is on the Internet for synthetic oils for one reason, most everything is in some way connected to Amsoil. They have saturated the internet, even making websites without their company name (the authers names are identical to those in the Amsoil websites).

That is because the API standard is controlled by the oil industry.

Amsoil is against the oil industry's testing methods and corrupt business practises 9aka the bullshit 3000mile oil change).
