Porsche has made many unsubstantiated claims about how long you should go between oil changes; only problem is used oil analysis says the even the best full synthetics are pretty much dead by 5-6K. Change it sooner, your engine will appreciate it, and ultimately so will your wallet.

It may just be me but that seems to be a lot of sludge for 10k miles done in 6 months of driving, which I would think means you must have a lot of freeway type miles. The sludge would IMO be more likely seen in a vehicle with a lot of stop and start miles. So just curious, What oil are you using?

But if you've been on this forum enough to post 200 times...you should've read at least once that the service manual is wrong.

They also state the IMS is a lifetime bearing and they were pretty much wrong about that in most cases as well. The best and cheapest line of defense is to change the oil early and often. 3-5k miles or at least every 6 months.

Fresh oil . . . the cheapest insurance you will ever buy for a Porsche or any other vehicle. Do it yourself and save money while learning more about your car.

Why every car does not have magnetic drain plugs is beyond me.

I suppose its one of those things a manufacturer can do to make sure the engine does not last too long.

Its like leaving a handful of abrasives in the engine and not doing anything about it.

You pay all that money for clean oil a couple times a year so why would you not also want to filter out all the abrasives out of your engine that never make it to the filter.

Magnetic plugs are cheap compared to replacing bearings or much worse.

Aluminum particles unfortunately are not magnetic and you rely on the filter for those, but aluminum is softer and causes less wear on the harder high load parts so their effect is not as much of a worry.
