Hey everyone its about that time to change my Transmission / Diff oil. I was curious to know what brands everyone uses and what the pro's and con's are. I'm the second owner of this car and I honestly can't believe I have put over 10k miles already only having it for a little over a year now. Thanks for your inputs.

 

CASTRO SYN.......

 

Redline.

 

Redline in mine

 

Amsoil, and let me know if you need someone to do it for ya.

 

Redline is by far one of the best. But Lucas differential oil is also really good. I personally used Lucas on customer's M3s who want more of a high performance oil. Some of them said they actually felt a huge difference, the driving was smoother. But then again I never put them on the Zs so I don't know how they feel. But if you want to put the best of the best, Redline is your answer.

 

I use Redline in mine.

 

I use...

Redline - Tranny Fluid

Amsoil - Diff fluid

Both = FTW!!!

Major difference in my shifting and response

 

I uses

Eneos, or motul for oil.

Motul diff.

 

PM me on what you charge for labor!

 

just make sure to put GL-4 in the tranny and GL-5 in the diff...... per the service manual.

 

Used mobile 1 synth for diff.

 

Motul for all our fluids in our Z, engine, transmission, and diff.

 

I use Royal Purple 75W90 gear oil in both.

 

Amsoil for me for engine, diff, and transmission (manual). I used redline from 30k-60k btw, no problems to report. Same thing can be said of my current setup.
