Dave,
I'd be interested in your take on the Schaeffer line of gear lubes that specifically say they are non-corrosive to brass and non-ferrous metals, and enhanced protection for copper.
Just marketing ?

Thank you amsoil for inventing a great oil and keeping the other makers competitive.
Alright enough about mobil 1 and amsoil.
Dave that's some interesting info and I didn't know you worked for a trans company which is pretty cool.
Which gear oil do you use and why? I undertand you like 4 in the box and 5 in the diff which makes perfect sense to me and that's what I've always done unless someone else is putting their oil in. As mentioned the porsche shop I think just put in some GL-5 so would you advise draining it and putting in something else or just shift slow. I'm serious about my shift style I'm mad slow

In a perfect world we could get a set of synchros that are made with braking surfaces (carbon?) that bite harder to allow the use of synthetics better. But our transmissions are just too old and few for that.

I'm going to ask my mechanic to check out this thread and see if he has any input. He's been tearing into various transmissions for years, usually race cars so his input could be useful.
Rice,
Is there someplace you'd recommend for having UOAs done?

I use Blackstone because it's cheap and I'm just looking for the basics, plus I like the layout of their reports, but I've heard Spectra provides a more detailed (and more accurate?) analytical report

I'll drain the oil in 14k mile car and have the OEM oil analyzed and in about 6 months to a year I'll have the red line oil analyzed in the 36k mile car. I'd expect the redline to look better but if it doesn't then that will definitely clear up all the redline mysteries.

The S2000 has carbon synchros, and it shifts very nicely. Good thing because you're constanly working the gearbox in that car.
