So i read so much post and didn't find my anwser. I got a 350z turbo and i put redline 80w90 Gl5 1.50quarts so my question is did i want a additif for differential ? Or just oil is best ?

 

Welcome, but it helps to provide a bit more information. What kind of differential is in your Z? Is it one of the OEM units or does it have an aftermarket LSD?

 

I dont know :/ but its a lsd i think is the oem 2003 with edition brembo brake

 

Well, it's difficult to know what kind of parts are on your car if YOU don't know! If it's the stock VLSD (viscous limited slip diff), than 3 1/2 quarts of GL-5 80-90W should meet Nissan specs. There's no friction modifier or other additive required.

 

1.50 quarts

 

Sorry- thinking of the gearbox capacity.

 

Thanks but its 1.50 quarts differentiel oil gl5 80w90 no additif its perfect ?

 

No, you don't need an additive for the diff.

 

Thanks a lot

 

Yep
