Hard to find yamalube. In the manual they recomend grade 1: 10w30, 10w40, 5w30 SAE: SE,SF,SJ,SH,SG,SL and grade 2: 15w40, 20w40, 20w50 SAE: SH,SJ,SL. Looking for the best alternative: diesel/sn or gasoline.

Just talked to a tech in Canada and he did not recomend using 15w40 diesel oil in my outbord engine: "deposits will be everywhere". shoul I use Delo SDE 15w40? or not! Thank you
