I have an 85 Spider and I should change the transmission oil. What are you guys using? Synthetic? thanks, Ezra

Search the site and you will find many good discussions on this. Study before you buy.

The one I am ordering is Redline Oil, 75W90NS, part number SS118, $10.95 each from Centerline Alfa Romeo (888) 750-ALFA

For a regular nonsynthetic, any decent quality 80W/90 or straight 90 should be fine. Some folks find synthetics improve the synchro action, others don't.

syntetic vs dino makes a difference in cold weather.
I had shell spirax which was good until the cold weather set in.
I had changed to red line synt so that I could shift in freezing weather.

I've read on the forum that some gearboxes will leak with synthetic oil when they do not leak with regular oil.

Synthetic: redline 75W-90 NS (non-slip). Can be ordered from Centerline
Regular: Shell Spirax 80W-90 HD. Can be ordered from IAP

IAP also carries Redline 75W90NS. You will need 2 quarts.
