I dont know much about the PS company, that is all i used to use before i decided to try amsoil but i feel amsoil has a better product now that ive used it a little while and actually experienced the difference.. The PS doesnt affect combustion for easier starts as much as the amsoil does, at least the way i use it.. But it does work for keeping your fuel moving when things get chilly. I just keep my additives at home in the garage and fill up on my way home from work when i get there roll inside and add the treatment! so much nicer than dealing with the inevitable spills and dealing with caps and measuring when its -10 and the wind is whipping around you at the fuel pumps.... Long Live VW and AMSOIL!
