Reported cause
I change mine every 5K and while it doesn't look terrible, it does look like it is due to be changed.

if more Porsches suffer engine failure, then there are no more trips to the Porsche dealer parts desk and no more future appointments for jacked up oil change bills.

Suggestion
Long oil change intervals, along with "permanent" automatic transmission fluid have to do with European environmental restrictions - not engine duration (think carbon foot print).

For the newer models in which they still might have some liability to cover parts/labor, well you best be changing your oil frequently, or we'll void that warranty too.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

This link is still up for maintenance intervals on
Porsche.com
, it was last updated in 2010.
For m96 engines they recommend 2001-2004 Boxsters (assume its intent is to address single row IMS?) oil to be changed every
12,000
miles or every 2 years.
For m97 engines they recommend these 2005-2007 engines have their oil changed every
20,000 miles
or every 2 years (???)
For 2008 engines (last year of m97) they bring it back down to
12,000 miles
BUT they want the oil changed at least
annually
for the first time.
For 2009 engines (no IMS), they cut the oil change to
10,000 miles
but want it changed every year.
Huh???
You would think Porsche would be doing its buddies at Mobil 1 a solid (= $$$$) by halving these interval recommendations. But no....
How can the factory and just about every expert and enthusiast community be at such opposite ends?
p.s.
This is not a discussion of your favorite oil, your favorite filter, why the other guy's oil sucks, etc. Simply trying to understand Porsche's position here.
The older cars were likely all out of warranty in 2010, so they don't really care if you change the oil. They can sell more Porsche replacement parts that way.
For the newer models in which they still might have some liability to cover parts/labor, well you best be changing your oil frequently, or we'll void that warranty too.
The updated 2016 chart will probably have "At your leisure" listed for the M96 intervals.
Wait a minute... if more Porsches suffer engine failure, then there are no more trips to the Porsche dealer parts desk and no more future appointments for jacked up oil change bills.
Maybe Porsche and LA Dismantlers have some hush hush deal on the side? (kidding).
These water-cooled engines aren't all kicking the bucket at 100K miles. Some forum members here like Floridabill who apparently follows strict dealer service, are well into the 300K mileage territory.
The water-cooled engines do not require engine rebuilds as a regular part of this ~80K-200K mileage which seems like a way for Porsche to keep selling parts and scheduling service for Boxster/996 fleet.
Especially if the cars still look great on the outside.
If Porsche have determined that the used buyer in a good % (whatever that number may be) will not consider a brand new or CPO Porsche, and their only way to bring in revenue for these drivers is to sell them parts/service wouldn't they have an incentive to keep the engines properly lubricated?
Personally. I have always thought that oil is cheap compared to engines, especially Porsche engines. I change mine every 5K and while it doesn't look terrible, it does look like it is due to be changed. It may not be necessary, but it certainly makes me feel better.
Long oil change intervals, along with "permanent" automatic transmission fluid have to do with European environmental restrictions - not engine duration (think carbon foot print).
I read a good link about it when I was changing the transmission valve body in our Touareg. No way in hell does auto trans fluid go forever. By claiming the fluids don't need to be changed, it allows them to pollute more in other ways and get a pass.
I'll see if I can find a credible source.
