Hello to all. Its time to change my transmission oil ! The manual writes " AGIP SP FE LS SAE 75W/90" Shell advices "Spirax S5 ATE 75W-90" Agip ( ENI ) I found 2 recommendations: "ENI ROTRA LSX 75W-90" or "ENI Rotra MP 80w-90" Any ideas which oil is better from the 3 above ?
Just to confuse things, I'll give you another option: Ravenol VSG Gold 75W90 It is the only GL-5 oil I could find that was specifically recommended by its manufacturer for transaxles. Been using it in my TR with no complaints. https://www.ravenol.de/en/products/usage/d/Product/show/p/ravenol-vsg-sae-75w-90.html https://www.amazon.com/Ravenol-J1C1109-SAE-75W-90-Gear/dp/B00QL31M3O/ref=sr_1_2_sspa?ie=UTF8&qid=1547168328&sr=8-2-spons&keywords=ravenol+75w-90&psc=1
use redline MTL and nothing else! https://www.ferrarichat.com/forum/threads/redline-mtl-big-improvement.573814/page-2#post-146849349
Yes, those LS specs seem OK (and does say good for transmissions), but more focused on the limited slip aspects rather than the transmission aspects. The data sheet on VSG seems a bit more expansive for the transmission issues and specifically mentions "better when cold". I haven't noticed any limited slip issues with the VSG, but please give a report back later if you try the LS. If I had some limited slip chatter noise when slow-speed turning with the VSG, the LS would be an option that I would consider. Not GL-5 so that's off my list for a TR/512TR (even though some pro F shops use it).
if you want something that works MTL is way to go. maybe in texas you dont get the notchy second gear grind we get in the northeast cold
I have over 109k on my 512 TR original tranny I use the Mobil one 80-90 Never had any issues what so ever
