Topic The proper redline is the MT 80w90, not the 75w90. Do you know for sure which you used? |
What bits do i need to change the gear oil in a 2000 S 6-sp? grant - Wednesday, 17 April, 2013, at 8:47:13 pm |

Thanks for the tips. I like the idea of turning a wheel. Now, why do you suggest only Porsche gear grant - Friday, 19 April, 2013, at 6:25:06 pm |
If you elect to use a non approved gear oil you can pick any one you want. Since you choose... MarcW - Friday, 19 April, 2013, at 6:58:37 pm |
That's a rather extreme position. grant - Friday, 19 April, 2013, at 8:40:09 pm |
Like I said you can use any reasoning you want to select a fluid. If you think the Audi... MarcW - Saturday, 20 April, 2013, at 11:15:29 am |

I have no religious adherence to Porsche branded stuff. Ok, its guaranteed to be good, and its safe -i agree, but its not guaranteed to be the best. Look at their oil recommendations - those are clearly inferior, driven by CAFE.
At minimum i plan to buy the Audi fluid which is identical. It must be, Audi made the 5-sp box in the first place, not porsche.
The friction modifier makeup can be significant. We know that people looking to improve the performance of aging synchros often use a different fluid with different cocktail of friction modifiers. One one of my cars i'm very much in that boat.
I also don't recall even asking about fluid, but someone offered a strong opinion. So i'm asking for rationale. Seems fair. I might learn - or not.
Let's be real. Porsche brake f;uid - ate super 200. Porsche PS fluid = pentosin CH11. Porsche auto tranny fluid = Esso Lt7441.
If you were being serious, then, no, you cannot choose any one you want. It really must be GL-4 since the synchros are brass. Since i will be tracking the car, ultimately nearly exclusively, i'm also most concerned with hgih temp stability and low wear, not with slick shifting nor low temp performance.
Finally, note that the OEMs are also thinning out their tranny fluids. While they cant yet mess with 75w90 (or it would not be so), they are lowering the Cst values for auto transmission fluid - again in the name of fuel economy. This is not good for high temp wear one little bit.

MObile 1 is GL-5 (not 4+5) and has always had issues with balky synchros (which we have) grant - Saturday, 20 April, 2013, at 8:29:17 am |

No, I don't remember exactly which it was Boxsterra - Saturday, 20 April, 2013, at 5:24:37 pm |
OK, thanks. Incidentally, i subsequently found that: grant - Saturday, 20 April, 2013, at 5:48:22 pm |
Verify this: 6 speed fills to bottom edge of fill hole. 5 speed 11 mm below. *NM* Laz - Friday, 19 April, 2013, at 5:15:48 pm |
Are you asking or reminding me? Yes, that is correct grant - Friday, 19 April, 2013, at 8:48:41 pm |
More a restatement than anything else. *NM* Laz - Saturday, 20 April, 2013, at 9:01:52 am |
