Oil change intervals can be as short as 3,000 miles or as long as 15,000 miles on some new cars. Even the oil manufacturers recommend that you follow the oil and filter change frequencies shown in your owner's manual. So you should also do in your mower manual.
yes. i change every 100hrs which is what my mower manual says to do. i use synthetic though. if i were to use regular i would do it more often. it's not about being dirty it's about the oil not breaking down. would you be fine to run regular oil 100hrs? yes but it will be more broken down at 100hrs than synthetic oil would be.
