I have use the cheaper compatible brands for a 1000 mile flush, and then put some of the Amsoil PSF in there. It seems to work well in the Honda/Acura systems and is specified for it.
I have used Bardahl (turkey baster method) since this is the only PSF available here besides dealer's. I remember once I got some Pyroil PSF in US and it smelled exactly same as the Canadian dealer's stuff. Overall I have gone trough 5-6 bottles of the Bardahl stuff and winter time I do not get any nasty sounds from the PS pump.
