Morning all, I have an email from my dealer that my 06 mountaineer is due for a 50000 mile tune up, they're almost right on with the mileage guesstimate but before I spend the $$ I need to know what it consists of and if it's worth the money.

 

that info should be in your manual/maintenance guide. If you don't have it, you can go to www.motorcraftservice.com and click on owner guides on the left, enter your vehicle info, and download a PDF of it.
