Caymann S Oil Filter

[DG624]

I was looking (I can only afford to look) at the new Cayman S and the literature stated 20,000 mile oil changes due to improved filtration. Now That, I may be able to afford, a quality oil filter. Does anyone know what is new and if the filter is usable on a Carrera? I seems that this is long over due...who really wants to change 12 quarts of oil if you don't have to?

Change oil every 20K miles, engine takes a crap right after warranty period is over, owner forced to pay $$$$ to replace engine OR guess what?

PCA will make owner a heck of a deal on a NEW car....Brilliant marketing strategy

I know I saw this...I was trying to look up more info at the Porsche site but just ads. I may have to ask the dealer.

I wasn't questioning your statement...

It was my lame attempt at humor.....

We went to a little Cayman party tonight and I asked one of the salesman I actually like about the interval. He said if you actually drive the car on a daily or semi-daily basis the oil should be changed about once a year. He said the 20k interval would be about the same as following the "normal" driving condition requirements in any car manual. Fine if you cruise at 65 all day but not acceptable if you actually drive in the real world.

I think this could be good if there is a factory solution to oil changes every 6 months. If you get a chance take a look at this car...looks great especially from the rear. I was starting to think my car is more speedster than Carrera.

I bet the dealer would charge over $200 for an oil change on one of those bad boys!

Would you buy a Cayman coming off lease with 36K miles that's had 1 oil change?????

A lot of the modern German cars now go beyond 10k miles between oil changes. The reason is synthetic oils, decent filters but most importantly engine management that does not contaminate the oil with things like gasoline.

You can put any filter on your old car, there is still things getting into the oil (chemically) because your engine just doesn't run as clean. So, keep up the 5k mile oil changes!

What's the big deal? Porsche started pushing 15k Oil Changes back as early as `89. They say that the tolerances on the motor are so good that contamination is almost nil. Most chemists will say that contamination is the biggest reason to change your oil.

Search for the "oil bible" in this forum. It's an exhausting but informative read. There is nothing to be gained by stretching out oil change intervals. Engine heat breaks down long chain molecules - it's all very technical but the bottom line is "more often is more better".

Personally, if I've already sold my house to buy a Cayman, I'll also have the money to spring for an extra oil change or two...

My office overlooks the local dealership which has two Caymans... I rarely have lunch at lunch hour any more.... beautiful cars.

I think the air cooled engines may have more tolerance at startup...I would like to reduce the waste oil and still have protection. I think an oil analysis is the only true measure. I guess the answer is nobody knows of any new filter technology with this car.

My wife's BMW 525 has the same type of oil change scenario. We went to a "welcome to your new BMW" gathering at the dealership right after we bought it and there were many, many skeptical questions about that infrequent interval. Their head service manager insisted that with the new synthetics that BMW uses and with the technology that allows the car to analyze your driving habits, the car basically decides when it's time for an oil change. If the car is driven harder, it'll tell you sooner that you need an oil change. Drive it easier and the interval will go up. Interesting stuff.

By the way, the molecule chain breakdown, does that apply to the synthetics also?

I have no specific knowledge of the filtration used on the Cayman, but in general European engine oil filters are much less efficient than what is used in the US. That is one way to extend the oil filter life. The filter is so open that it does not plug.

I owned a BMW back in '86 and they had the service interval lights that would go from yellow to red. Red = time for oil change and other indicators for service intervals. My warning lights always hit red around 3500 miles.

When I began doing my own oil changes and maintenance, I would swing by an independent shop and have them re-set the computer back to yellow. Were the lights helpful indicators? Yes but that all they did, no magic...Iv'e always changed oil in my cars at 3K anyway.

Well sure, but that was literally 20 years ago. That was the stone age relatively speaking.

Agreed.....

Yes, but at a slower rate than dino. It all makes sense. I'd change it at 5k anyway, if I'd buy a new car that I would plan on keeping beyond 100k miles. Now of course, which new car buyer plans on that?

You'll always win if you treat your car like you'll have it a long time. Resale, repairs and reliability.

Otherwise, none of us would use never seize on exhaust bolts....
