Our dealer in Tulsa says that the version of the warrenty we purchased allows me to change my own oil (keep oil and filter receipts and note milage and date when changed) and other repairs covered by a 3rd party insurance company can be done by any ASE certified mechanic. I'd have to read the details to see if we have to call a 1-800 number to get the repairs pre-authorized first. repairs at our dealer are $100 deductable. If we wanted repairs with no deductable, we would have to return it to the dealer to have it repaired (a 200 mile trip).
FYI
