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.
