Why is it that the KT series and Magnum series still call from 30wt oil only? Upon installation into my JD 317 I used M1 10-30 for now since its cold out but I'm wondering about the summer time. What would make oil consumtion go up since its all a 30wt oil anyway at operating temps?
If need be I was thinking of running Rotella 30wt in the summer. "OR" Amsoil Small engine 10w-30/30wt oil
