I happened to be working on a kohler 18 hp as I read your post and the manual states that syn oil is good for colder climates. Iím putting full syn in because the owner starts it and immediately throws throttle full open. Itís in a Snapper ZT mower. Iím impressed with the quality and design of this engine, first one Iíve worked on etc. Our local dealer support is terrible since owner change so I got the 100 page tech manual and went to work on it.
