I have tried them both, And if i remember correcly i liked Red Line better..
But "People say" that Motul 300 is better..

I do alot of trackdays and ALWAYS drive my car hard.
And i think that Motul made my gears grind more than Red Line MT 85

What do you think and say?

 

Motul is trash idc what people say. It makes gears grind and the trans is so much more rough with it. I will say though at the track I had 0 problems so I guess what's why people like it


But say when I take off in the mornings I can not get into 1st until a complete stop for a second. 1st to 2nd is always iffy and rough. But once it warms up its all good lol


Next time I'll be going either redline

 

Redline 100%

IMO OEM or Redline, and I have been using Redline for the past 2-3 years, I just think it is in a league of its own when it comes to tranny fluid for the Z.

 

The other critical issue to consider is the lubricant rating. A synthetic GL-4 lubricant like Redline MTL85 is designed for use in syncro trannys. But I've heard of other Z owners who put a GL-5 lube in both the gearbox and diff. GL-5 utilizes high pressure additives, which can erode soft metals like brass and shorten the life of a gearbox.

Just make sure you get the Gl4

 

nissan

 

I've heard mix reviews about redline aswell and people switching back to oem nissan fluid.

 

So im not the only one that thinks Motul is overrated =)

 

Redline.
No issues 10k miles later still smooth even on cold winter starts
