A PSA for any who might not have been aware of a Porsche issue regarding incorrect info in Owner/Driver manuals (digital and printed) for 4.0 six-cylinder 718 models. The owner manuals were issued with incorrect information regarding the oil and the water access for adding the respective fluids. I know that 2021 model year 4.0 six-cylinder 718s were affected but I don't have information about other model years. Check your owner's manuals to be sure.

The manuals for both of my 2021 718s (GT4 & GTS) have the incorrect illustrations for the oil and the water top-offs. The filler illustrations are reversed, incorrectly showing coolant fill on the right and oil fill on the left, opposite of where they actually are.

Porsche finally issued a supplemental manual (in 34 languages!) a year or so ago after reports of owners adding water in the oil and/or oil in the water.

I've attached a scan of the three pages in English from the 34-language "Supplement to the Driver's Manual" correctly showing the Coolant on the left and the Oil on the right as they should be. Again, please note that this is for six-cylinder 718s only.

The cover of the supplement manual only states "718 Models" so I don't know what other years might have the incorrect info. It does say inside that it pertains to 6-cyl cars only.

I've attached the image scans of the supplement manual along with a PDF of the scanned pages.

Yikes, shades of the 1972 911 oil filler door door that looked exactly like a gas flap! Good PSA, thanks!

I should have posted this last year when the supplement was finally made available - it slipped my mind to do so.

Not sure why it took so long for Porsche to get the corrected supplement to customers but I guess better late than never!

My 2022 owner’s manual has the correct and updated location for topping of the oil for the 4 liter, 6 cylinder Cayman and Boxter models.
