Needing to do an oil change on my TT with Kaw 29 dfi engine. We just moved and I can't find my manual at the moment. What oil do these engines call for? I bought it last year and it was serviced before I bought it, so this will be my first service on it, would have liked to have done it before mowing season started but been in the process of moving for a couple months. Any quick help on this would be greatly appreciated as I'd like to get it changed. Have filter already, just not sure on oil.
