Amsoil ASE 30wt 4-stroke is rated API SL,SJ/SH Diesel CF ($7.00/qt)
Amsoil ATM 10W-30 HP Oil is Api SM/CF, SL, SJ ... ($10.00/qt oil)
As there is a price difference between ATM and ASE.... is ASE a GRP III and ATM a GRP IV?
Can they be used interchangebly in larger lawn equiptment engines as both overlap the API SL,SJ ratings?
The reason for asking is two fold....one I am interested in knowing this information as I am not an oil expert and secondly is that Amsoil ATM HP is available at Murrays down the street....ordering online adds $10.00/2qts for shipping.
Thanks
