A guide to engine oil capacities and dipsticks, 78-84

The following guide is the result of research used to answer an important question; what is the correct engine oil capacity for an early 928?

Seemingly simple question, however the answer was surprisingly more complex. See, from 1978 to 1983, Porsche specified 3 different oil capacities and offered 3 unique dipsticks!

The purpose of this guide is to condense specifications gathered from various Porsche publications, suggest a singular practical engine oil capacity, and identify dipsticks.

The scope of this guide is Porsche 928 from 1978 thru 1984. Engine oil capacity remained unchanged thru later years.

Thanks Jim - as always, great information!

Jim, you’re like a membership to the Jelly of the Month Club: you’re the gift that keeps on giving. :cheers:

I'm glad you found this info useful.
This started with the wrong combination of oil capacity and dipstick, which led to an over-oiling situation.
Lots of blue smoke, and an 'oh sh#%' moment, easily rectified once the situation was understood.

Resource updated to reflect Porsche is no longer offering any workable dipstick solution for 78-84. All NLA.

Also, before and after this resource, I continue to be astounded by the disparity in oil capacities people are using for their 928!
