doesn't ( most ) everyone here have the maint schedule saved to their desktop?!
i sure don't need a dealer to tell me much, but if and when i do, i count on it being costly.

The manual that's in my car says major maintenance at 30k miles as well. However, the current PCA website says every 24k miles for 01-04 Turbos. So I assume sometime in the last 10 years, Porsche shortened the period. See attached link.

What's confusing with my car, which is a 2005, this website says 2005-2007 every 40k miles. However, the 05 Turbo S is the same car as the 01-04 Turbos, not the 07 version, so I would think I should follow the 24k mile schedule. I'll find out when I schedule the maintenance.

me, i'd stick with the 30/60/90, but would NEVER try to get 30 k out of plugs ( if the car is TUNED / MODDED! ) one look is all it'd take to know changing them at 15k or so is the wiser choice. its a pita but how do you want the car to run?

tuned turbo's eat spark plugs.

Not me.

Since both of my cars get driven quite a bit and thus get their oil/filer serviced rather often I don't necessarily go by the service schedule for other things. I have the SM/tech check and see what's either due or close to being due and have that done along with whatever else I'm having done to the car.

I always do all the fluids and filters the first weekend of ownership. I take note on exactly the fluid levels, put a couple hunderd miles on then come back to see what it's consuming. A china marker is good for this, as you can just wipe away the mark when you've verfied nothing out of the ordinary. Usually I do my next oil change at 3k miles, and send it out to be analyzed, I'll also check the coolant for exhaust. After that, I follow the OE's recomendations. That said, if it's a vehicle I track I cut the fluid change intervals in half. I might not need to change everything, but I like to start my ownership with a clean slate.

that makes sense, particularly if your car has *relatively* high mileage. then one could throw the book away, and service as needed. that's what I've been doing on this one since 90k miles. my last one i babied and it never made it past 40k or so.

No changes 30K for plugs. Do coils also!

What is the result of plugs being left in a stock car too long?

I have seen some hard to get out most are not=a little blaster or kroil goes a long way. Some Fords etc really can get stuck especially with suggestions of 100k service life on plugs.

As others have said Turbos are hard on plugs.

The other concern is corrosion developing at the threads and to the point that upon removing the plugs the head threads are damaged. While these can often be salvaged one wants to avoid this if at all possible for it could require the head be removed if the thread can't be salvaged with the head on the block.

If you look at old/used plugs you can see discoloration starting at the plug tip end and extending up the plug threads. This is from the pressure of combustion forcing combustion gases into the space between the plug and head threads. (To keep this gap to a minimum is one reason why thread lube should not be used.)

These gases are corrosive and encourage corrosion between the plug thread metal and the head metal.

In the case of the plugs and heads, the plugs are the sacrificial items in the plug and head combination. The much less expensive plugs are scheduled to be replaced to avoid the risk of damage and premature replacement of the much more expensive heads.

Plugs removed at 30K with coils and the plugs were in very good shape. Hardly any wear, gap checked and was just a minor bit off. No unusual burn signs. Actually they looked like they could go another 20K or more. when replacing new plugs some techs use anti seize for aluminum.

100k between plug changes is insane.

"02996ttx50

i agree, it's on par with the madness of gear oil functioning well near 90k miles

PAULUNM

Or a 10k mile engine oil interval.

You guys sound so cheap. You are talking about an expensive car. How much are plugs and oil? I mean come on. Anyone who is saying 10k+ oil change is crazy. I'd rather know my car is as fresh and up to date as possible in relation to maintenance. What does that cost me? 150 bucks for spark plugs and oil. It's a joke.

In the long run, someone who changes the oil more often, that engine will last longer and less wear and tear.........END OF STORY.........its a proven fact.


Imagine your body with a liver that didn't filter the blood as often, you are a dead man lol.
