I like to smear some on a clean white paper towel, then you get a better idea of if and to what extent it is comtaminated with particulate matter that's visable to the eye.

New fresh, clear oil is always better, but usually dark colored oil will still lubricate, cool and work just fine.

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.

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

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

POST 1 / ORIGINAL POSTEROriginal post

Just changed the transmission oil. My car has only 23k miles and look how filthy the oil is! Good news is there's no metal shaving or debris in the oil. Porsche recommend changing the oil at 90k miles. Go figure. The shifting is much smoother with the fresh oil. In contrast, the fresh oil looks like cooking oil in color and consistency. - Ahsai

POST 2Original post

holy cow! Makes me wonder what is going on with mine at 40,000 miles....

POST 3Original post

I just had a transmission service (with rear & front differential service) yesterday at 81k My mechanic saved a small plastic cup of the oil to show me, it was like coffee, except with a golden black sheen to it. No metal shavings but there were some slightly-goey clumps though. And he showed me the new oil, just like what Ahsai described, like cooking oil.

POST 4Original post

Has anyone figured out a good source for Mobilube PTX for the transmission?

POST 6Original post

Looking at drained oil in a pan doesn't really have any significance at all, only that it looks darker than unused oil. Heat and contact with metal parts, bearings, bushings, condensation, oxidation, etc. will all cause oil to look darker. New fresh, clear oil is always better, but usually dark colored oil will still lubricate, cool and work just fine. I like to smear some on a clean white paper towel, then you get a better idea of if and to what extent it is comtaminated with particulate matter that's visable to the eye. Magnification can pick up smaller stuff. Bottom line, it's usually not as bad as it looks.

POST 7Original post

Anyone use redline tranny or diff oil? When I replaced both in my 300zx, the shifting got noticeably smoother...

POST 8Original post

POST 11Original post

Have it analyzed! http://www.blackstone-labs.com/

POST 12 / ORIGINAL POSTEROriginal post

I agree it may not be as bad as it looks. The shifting is much smoother now though. I have Porsche ssk so it's quite sensitive to anything not smooth. Also, the ssk may put more stress on the transmission than the stock shift. It's a simple DIY (check out renntech for instruction). Both my plugs are 10mm hex. The most time consuming part is pumping the oil back in. I used a hand oil pump. 30 pumping to get 1L in and it needed 2.7L. - Ahsai
