I've read on other threads and the popular recommendation seems to be to use GL5 type oil in the 914 tranny. I thought that GL5 was for newer transmissions and shouldn't be used on trannies with soft metal (brass, etc.) parts. Doesn't the 901 tranny have brass bushings or other soft metals?
So, straighten me out, please. Which oil should I use in my transmission?java script:emoticon(':blink:',%20'smid_17') |

Where's a good place to buy this stuff? The few places that sell Brad Penn online, don't carry GL4 80w90. I even tried Brad Penn's website and only listed 1 store front store that doesn't carry it and a few website that don't carry GL4.
Should I just give in to the Swepco? |

GL5 in a 901 (914) manual 5 speed transmission.
If you can't remember this, then just think that a larger number is better. Five is better than four. If you still aren't sure, open your hand wide, and count the fingers. GL what???? GL5. If you are missing a finger because somebody punched you in the nose when you were picking it, then go ahead with GL4. If you still have all your fingers, count them and go with GL5.

GL-5 is recommended for the 901. My local vintage Porsche shop agreed. I used Coastal (generic) GL-5 oil from Autozone and it works fine. I couldn't find Swepco 201 locally.
