Fluids

["Brad Meilink" <bmeilink@domain.elided>]

Can someone point me to a link which details the current oil(s) recommended
for a 87 Spider?  I'm not having any luck finding the Shell Fire and Ice
10W/50 motor oil recommended in my owners manual.  I just bought this car
and want to change all the fluids.  I've got Redline 75W90 coming from
Centerline for the gearbox.  What should I use in the differential?  Someone
said to use Mobil 1 15W/50 in the engine, but at $4 a quart it is a bit
steep.

Any and all advice welcome.

Thanks,

Brad
