These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

24 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 6Original post

Quotes source post: 6045932

um, i would have to disagree with that. There are no blanket statements and my oil analysis at 8K miles comes out clean as ever. I've sent in oil at 13K miles and it's still clean. The frequency of oil change is totally dependent on driving environments and how you drive the car.

POST 7Original post

Most Porsche are driven fast as well as they were designed for. 20.000 km are too much. My mechanic sent several samples to the lab and the results were that more than 10.000 km seem to wear the engine parts. Jake Raby, Autofarm, and other Porsche specialist advise to change the oil at least once a year or 10.000 km The oil is the life of the core. I live in Madrid. Now we have 30�F and in summer the mercury rise till 108�F . We don't have snow (once or two days in winter as max) , and don't need to storage the car, so we can use everyday. Cold starts, hot conditions, driving fast... 20.000 km? too much... I respect what you are telling us, and don't want to argue, but I have a different opinion about oil.

POST 9Original post

I consulted an oil expert and advised me to use Mobil 1 5W50 Considered 0W40 too thin Mobil 1 5W50, Motul Xcess 8100 5W40 was another option

It's somewhat interesting sometimes when people start a thread and ask a question which would take about the same time to go out, grab the manual, and READ it. I guess clicking a mouse is easier than READING?
