i have used everything from the 15-40 fleet type oils, straight 30wt hd's, and the type 3 synthetics as well as mobil 1 ss in my lawn equipment. i used to change them several times a season as they see quite a bit of use. recently went to amsoil atm 10-30. i plan on changing at the end of each cutting season right before winter storage. buy it localy for 5.85 a qt. penzdude
