Re: Gear Oil

[Caxambu@domain.elided]

I am running this blue $38/gal. Swepco 80-90wt gear oil in my '69 Spider's 
tranny and differential. Came highly recommended to me too, from local 
racers, same story about the Porsches, etc. It DOES leak out, more than the 
90-wt cheap stuff (Sta-Lube?) I had been previously been filling them with, 
from the local auto parts chains, thou maybe less than straight synthetic. 
Also weeps out the fill plugs, where it did not before. Also, the gearbox and 
diff are very noticibly louder, the gearbox more of a scuffly bearing noise, 
esp. at idle, the diff more of a one-note whine at 70MPH. Shifting is maybe a 
bit better, but I wonder how much changing the oil brand is going to help an 
old gearbox. With a new gearbox maybe there'd be more of a difference. Swepco 
does have an informative web site http://www.swepcousa.com/
