Going over the Porsche recommended maintenence (and having just completed my 40k service) I'm wondering what else may need attention. Specifically, lubrication points like sunroof, hood hinges and latch, door hinges, etc. A lot of these things are documented by other manufacturers as part of regular service, but I see nothing recommended by Porsche. One thing they do recommend with oil changes is Keropur. https://www.porsche.com/china/en/acc.../fueladditive/
Anyone use Keropur?

 

Sounds a bit like Marvel Mystery Oil. The link you posted is for China. It probably is not necessary if your are using a U.S. brand Top Tier gasoline - the detergents in them prevent deposits.

 

There was a really good video posted a few months ago showing a Porsche Senior Tech doing some of these additional maintenance items from Loeber Porsche. Search for it, or maybe someone remembers and can post it here.

 

Here are some of the things I would do:
Clean Throttle Body
Clean Battery contacts and coat them with anti corrosion nano coating.
Clear drain lines
Clean and lubricate all rubber seals and grommets on doors, sunroof, engine bay, etc.
Re-torque wheel lugs or center locks.
Send oil for analysis.
Remove front bumper and wash clean radiator fins.
When replacing interior cabin filter, clean whole system with proper AC system cleaner spray.
Lubricate top of the Struts.
Lubricate all hinges and front hood and rear struts.

Regarding fuel system cleaners I use Chevron Fuel System Cleaner two tanks before oil change.

 

Thanks. Curious what you use for pivot points like hinges. I lubed the hood hinges and strut contact points as well as the frunk latch pivot points. I lubed the sunroof rails, but still get some squeak on closing. It seems like most of these things are designed to be maintenance free, i.e. no lube recommended, but they seem to work better after some lubrication.

 

I used to use T-9 but recently changed to Wurth HHS-K, PTFE Dry Lubricant, True Glide for sunroof rails and Rubber Care Silicone Free, replacing Gummi Pledge.
Wurth products are only available for corporate accounts but you can purchase T-9 off Amazon.
