My thread about overfilling the Kohler engine, led me to some other questions;
Do you have a particular brand of oil you prefer?
Viscosity? Detergent or non detergent?
I use straight 30 weight in the older engines that only run in the summer months.
10W30 is what I use in the JD that is run summer and winter.
