Tom your right on the money here.4by4bygod said:There is something called a group II oil, which is a mineral oil that's been refined and hydrotreated many times over, making the molecules pretty similar. That's how castrol is made, and they won a court fight, being able to call their oil synthetic too, just like the PAO's.
You also have ester based oils, which are good at absorbing heat, but will also swell your seals. everyone went to PAO because it's cheaper than ester, and of course the group II's are cheaper still. redline is an ester base, and amsoil used to be.
pretty much any PAO , ester , or mineral basestock blended with solvents and detergents can be called a synthetic nowadays, thanks to the castrol court case. The trick is to study the different types of basestocks, and how they react under combustion temps.
