G50/50 Lube
I went looking in the archives to find the lube folks are using in the G50/50, but did not find an answer. What are using? SWEPCO, if so which one?
Thanks, Bill |

Does it have a limited slip?
I use Mobil 1 LS 75-90. I tried Mobil 1 Delvac but I the diff didn't like it much.

Bill,
My G50/52 has the limited slip differential and I used Mobile 1 Delvac. I'm not sure what was in there before I changed it. I noticed no change in performance or problems. Here is a link for the source I used: http://www.lufteknic.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=lubricants 1 Gallon of Delvac 75W-90 was just about right. Just make sure the oil meets the Porsche specifications: API GL5 for mineral oil or Mil-L-2105B for synthetic oil. Mark

Both LS and Delvac are rated GL-5.
Many swear by Delvac. Maybe I got a bad batch, I don't know. I was fairly certain that the Delvac was going to destroy my diff; it just wasn't slippery enough.

Bill, post your results when you do the change. I'm curious to see how Delvac works out for you...
