As the title says, what LSD fluid are you using in your street ti? I was lucky enough to pick up a small case 3.45 LSD from Dan and will plan to install it this weekend. I looked through various threads, but there was no clear answer other than fluid weight. I figure our responses can help other folks with similar questions in the future. I see 75-140w for LSDs, although a 75-110w is used by some folks to keep heat down. 75-90w seems to be the spec for non-LSDs, although some folks are using it in their LSDs without apparent issues. Dan mentioned he used Redline, which I have used in my non-LSD diffs. Not sure if a LSD modifier needs to be added to Redline. What do you use? Whatever you use, do you hear any difference when you are driving? I ask as I tried Royal Purple when I could not find any Redline at one point in another non-LSD BMW and I experienced a whine when underway. Not sure if was due to the fluid change or if the properties were different than the BMW fluid. I went back to BMW fluid and the whine went away. Never was really sure what went on there. Also, can you mention if you are running a LSD or a Torsen diff and if a LSD, is it a small case 3.45 or a E30 or other variant? Anyway, thanks for your feedback!

Not sure what fails but he has mentioned that in other threads. I've mostly used Mobil 1 and amsoil both have held up well at ~20k mile oil change intervals. 75w-110 is what I've been using in the Ti with small case LSD. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 04-08-2014, 06:11 PM | #6 | Senior Member Join Date: Feb 2012 Location: Sacramento, CA Posts: 2,451 | Hi Dave! Yes I read the same threads for Redline "shockproof" which caught my attention. I wondered about the use of 75-90w for our LSDs. there is a speed shop in town I'll head over to later this week and they carry Redline, Royal Purple, Valvoline and a few others where I can read the labels. Old school... I'll open up the case hopefully this evening and inspect the inside. Thanks again for all responses thus far. __________________ 1998 318ti Sport - "Cali" Schwartz II/Schwartz sport interior, Cali top 1998 318ti Sport - "Max" Schwartz II/Schwartz sport interior, S52 1997 318ti Sport - "Tiny" Schwartz II/Schwartz sport interior 1995 318ti Active - "Blanca" Alpineweib III/Schwartz leather interior Other Current Bimmers: 2006 530i / 2000 2.3L Z3 / 1997 1.9L Z3 / 1999 540it 1997 318ti Sport - "Huera" - RIP 1995 318ti Active - RIP 1995 318ti Sport - "Tiny" Sold 1994 325i Sedan - "Jade" - Sold 1991 318ic - "Bert" - Sold 1985 635csi sold 1984 533i "Max" Sold 1984 318i sold BMWCCA #160411 SUPPORT 318ti.org!
