The more enlightened companies state these things correctly in the owner manuals, but with H-D you have to go in already knowing your rights under Federal law. Look up the Magnusson-Moss Warranty Act and you will find that you do not have to have them do the maintenance, and you do not have to use their fluids and parts. If they want to limit you to having the maintenance done with their products and by them, they can only do so if they provide those parts and services free of charge. Don't hold your breath waiting on H-D to provide free maintenance.
It's funny how different companies do these things. Just picked up Momma's new 2010 Edge yesterday, and looking through the maintenance and warranty booklets it was very refreshing to see an honest presentation of your rights. Sure, they "recommend" having your dealer perform the maintenance using Ford parts and lubes, but they come right out and say that you are not required to do so.
