Suggestion

I was thinking of using 90 weight oil so it takes longer to break the oil down, instantaneous engagement of the Variocam at about 2,000 RPM less than before, and push the new oil change interval to about 85,000 to 95,000 miles......any thoughts?

Interesting enough, for the 997, which has essentially the same engine, the oil change interval is 20,000 miles.

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.

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

  • Rennlist: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I know that oil is a touchy subject and I normally stay well away from it, but I came across this link at another forum and I thought that it might interest some here - I hope it hasn't already been posted. http://www.lnengineering.com/oil.html

POST 2Original post

I read the first couple of paragrahps and found this: "Detergent oils contain dispersants, friction modifiers, anti-foam, anti-corrosion, and anti-wear additives. These detergents carry away contaminants such as wear particulates and neutralize acids that are formed by combustion byproducts and the natural breakdown of oil. " The additives he refers to are not necessarily contained in DETERGENT oils, yet most of them do. Non detergent oils may have these additives as well. Detergents only carry away contaminants when the oil is removed or drained from the motor as detergents hold contaminants in suspension. Detergents do not neutralize acids, calcium carbonate compounds do and have nothing in common with detergents. Acids are not formed by the combustion byproducts and the natural breakdown of oil. I think the author needs to have a better understanding of the subject he is writing about. Anyway to keep my interest beyond the first few sentences. I hope it gets better.

POST 3Original post

Hello, to avoid a lot of wasted time these links may add to more understanding about engine lubricants https://rennlist.com/forums/993-forum/342882-oil-again-mobil-1-15w-50-new-formulation.html https://rennlist.com/forums/911-forum/341405-oil-question.html Regards

POST 4 / ORIGINAL POSTEROriginal post

Nice thanks! These sort of things don't normally make it to my radar screen, as I basically let the dealer do whatever Porsche recommends, but this one might be worth watching more closely if the trend continues.

POST 5Original post

Oh Wayne, what have you done????? Popcorn machine at the ready!

POST 6 / ORIGINAL POSTEROriginal post

I know - I didn't want to do it, but I thought that the article was interesting. I normally try to stay away from this subject entirely, but I figured that it was worth throwing out there to get comments.

POST 8Original post

Pass the butter.....I think I'll need the extra large for this...

POST 9Original post

man..... that's going to need more then just butter!!!!!!

POST 11Original post

That's a good one! Here's another article (old one, though) on OIL that might spice up things a little... Are All Oils Created Equal?

POST 12Original post

Hmmm - I was going to make a new post asking what the first oil change on my soon to be delivered 996 should consist of, but given the tone of this thread maybe I'll do a whole lot of searching first. That said....what's the general consensus for a northern west coast climate? Is it true I only *need* to change my oil wvery 10,000 kilometres? What about transmission fluid? Brake fluid? Thanks

POST 13Original post

I change mine by the manufacturers recommendations (15000 miles), and have the drain oil analyzed at a lab every time. So far the oil is fine, and wear is well within design tolerances. Vancouver is much like the Bay area, so I would recommend the same change interval for you.

POST 14Original post

Is 15000 miles really the recomended interval ?!? seems kind of long. What actual oil do you use? Thanks - actually I am going to post a seperate thread ?

POST 15Original post

POST 16Original post

Oh GEEZ guys....how bout we agree to eat what popcorn we've already made and move on to another subject? I'm getting sick of Orvel Redenbacker.

POST 17Original post

Has anyone ever heard of and/or used Penrite Synthetic 5 ? The results from this oil test that was posted on one of the threads are pretty impressive.
