Hey guys currently i'm running OEM fluid in my 03 Z. It's due for a transmission oil change and i've been recommended to use Amsoil 5w-30 Synchromesh. Now to my understanding it's a lighter viscosity. My question is has any one used this in their Z before?

I did a search and found people trying the Manual Transmission & Transaxle Gear Lube 75W-90 but not the Synchromesh. Any thoughts?

 

75w-90 is recommend and you want to put 5w-30 in it?

 

This is why i'm asking because a place recommended the synchromesh, i looked it up and it was 5w-30. Which doesn't seem right to me.

 

Yeahhhhh dont do that.

Do this; I actually think I like the Amsoil over the Motul I used this year. Seems less clunky.

 

Ahhh okay that must of been what they were recommending. Thank you!!!

 

Makes sure its GL 4 spec fluid like on that bottle above.
You do not want GL 5 in your manual transmission.

Another good brand is Redline for fluids.

 

redline specifically makes tranny fluids for our Z'.....

Redline MT85

 

Good to know! Probably gonna use this for my upcoming tranny flush

 

Just got the MT-85 Redline in, Good stuff, Should have it up on the site any day now.

 

80k on my trans with that fluid (40k changes) with heavy track abuse. Still going strong.

 

We use a ton of Motul here in customer cars and have had nothing but positive reviews and results. We have also used the Redline MT85 with great results.
