Differential fluid

[Journeycastro12]

Hey all replaced the differential fluid in my commy a couple months ago and recently when I go around corners it’s locking up way too early, and causing “chittering” I think it’s called. I’ve heard it could be because I used the wrong fluid, so I’ve gone and got some new stuff. It says in the manual I need Castrol SAF Carbon Modified 75W-85 GL5, but nowhere locally sells that so I’ve gotten Penrite SAE 75W-85 API GL5. Before I bother since I did keep the receipt, and Can swap it hopefully, should it be fine??

You need Penrite gl5 full syn 140.

It is full synthetic gl5 penrite but not sure what the 140 means

140 is thicker and hangs on the gears better. What you have will be ok. What you have is probably factory spec. I'm on my phone and can't be bothered looking up the factory recommended oils.

Ahh okay, it is an lsd but there’s so little information on them it’s so annoying

if its LSD then just get the nulon LSD additive which helps, chatter usually happens when a non lsd fluid is used
