Btw, for the guys who are changing oil now as part of the spring chores, you should do it in the fall instead.
Oil will become acidic as you use it. If you leave that in the engine all winter, it's not ideal. If you do the oil change in the fall, you leave fresh oil in the motor and you avoid that issue.
Maybe it isn't significant, but it can't hurt. Besides, there is enough to do in the spring, just make it part of winterizing instead.
I know the OP just hit 10 hours, so it doesn't apply there.
