I am a new to me owner of a JD 318. I will probably want to change the oil soon. Not sure what the previous owner used for oil. I’m wondering if any of you 318 owners are using the Amsoil 10w30 30 small engine oil? If so any issues like leaks? Any oil consumption? My other option would be is to use JD TorqGard 30W conventional. I will only use this in the spring and summer for mowing.
