Hey Brad I hope you feel this is on topic because I was going to start an oil thread asking about synthetic oils. I have been reading about different synthetic oils with different base stocks Amsoil is supposed to be POA base stock oil with ester base stock being the best and POA being second best but much cheaper. My transmission builder uses amsoil in his 1500 hp nitrous engine on alcohol and is very happy with it. Maybe some of the chemists will chime in.
