Hi Guys,

I have some stock of Redline 75W90 that is 6+ years old ...
Is this still good to use, I'm planning to run it in my Cayenne front and rear diff.

( I been getting around to do the change for a while now lol .. 5 years haha )

Castrol site says to use - Syntrax Long Life 75W-90 I'm sure I can find it somewhere too

Factory calls for Burmah SAF AG4 ( Castrol ) ( I have some OEM fluid as old .. but I think Redline might be a good fit )

Thx

I sure hope so. I just filled my GMC van with Amsoil that was much older than that!

You can call Red Line and speak to Dave the tech guy there about your Red Line oil.

i am in the same boat! i store my oils in the hose but have some MT-90 + MT lite in the garage for a while. i guess viscosity improvers are active during temperature changes but with the small spread + fact RedLine is true synthetic little if any are used!

I have never seen any additive precipitation in Redline products, but it is always a good idea to warm up any lubricant and shake it before adding, especially after having been in storage.

So you're saying to take a bath with it right? Seems like a good way to warm the bottles up and shake 'em up. banana
