Workshop manual for Porsche Boxster and oil changes

I have a 2006 Porsche Boxster. I would like to do my own oil changes after the warranty expires. This shouldn’t be rocket science, should it? I mean, are there special tools I would need to change the oil on this car? One of the problems I have is that I can’t get a workshop repair manual or maintenance manual. Do you know where I can get information on changing the oil and doing other minor maintenance procedures on this car? Thanks for your help.

Use your most valuable tool, the internet. Tons of info out there, especially at a Porsche Boxter owners forum. Also try you local library. Buy an owner’s repair manual though, search online.

Open cap in the service tray in luggage compartment.

Hey Kathy,

There are a couple great forums out there for technical help for the Boxsters.
I’m on Renntech and on 986 forum.

Both should have a FAQ on how to change the oil in your car.
There are a lot other great sights from members of the Boxster community, with step by step pictorial instructions, like on Pedro’s Garage website.

If you can’t find this one useful, let me know, and I can find plenty of others for you.


Unfortunately, the Bentley manual is for the older (986) version, not yours. Might be worth checking with them on when the 987 manual’s coming out.

Thank you for the information.
