What is the special maintenance schedule. Nothing in my owners manual about that.
You're right, that was my mistake. I see that's not part of the SD manual. At one time the severe use cycle was followed if using E85. Maybe over time they realized this wasn't necessary or these newer engines don't need that requirement. I haven't looked for years since I stopped using E85 altogether.
