OK - FWIW I own a very nice ERA cobra and service others,...i also own and automotive shop that provides
oil changes as well as full service autorepair. Our lube bay is three pits with techs working underneath and we plan for about 10
oil changes per day (approximately one per hour). We could do them a lot faster but we really want to be know for our Quality.
If you are going to do this (or anyone on this forum) - here is what you should do and know.
1) Like any good shop - they should be happy to purchase any
oil you like. I stock just about every major brand. They will be happy if you let them purchase it b/c they are no doubt going loose money just doing the oil change itself. Getting the oil from their wholesaler will help them lose less money. This goes for the filter too.
2) Schedule an appointment - no one needs to be rushed when working on a speciality car. I never allow more than one "special" car in the shop at a time.
3) You should be allowed (with someone guiding you in) to pull the car in and out of the service bay - esp if the shop has a pit. YOU DON"T WANT SOMEONE driving that car into a ten foot hole in the ground.
4) Ask (and be willing to pay) a ASE "high level" tech to do the oil change - For 'special" vehciles like these - only my Master Tech performs such repairs.
I hope these pointers help - I think if you can find the right place you should be able to give up oil changes for ever.
Good Luck and PM me with any questions.
