Well I just recently Installed the Nismo 1.5way LSD on my 07 base. In another 400 miles or so I have to change out the fluid after the initial break in. I have been looking up and most of you'll say Motul, some say lucas and others say amsoil. With lucas or amsoil do I need to add a additive? Which of the three and what weight viscosity is the best?

Same thing for the transmission fluid? Which and whats the best?

Any input will be greatly appreciated.

 

Diff - Motul 90a

 

No offense. But wouldn't it of been wise to have done all yrou research before you spend $$$$ on a Nismo diff AND installed it AND now 400 miles away from your fluid change?


To add something useful....unless you are FI or really beating the crap outta your car, regular Nissan tranny fluid is fine. When i got my new tranny put in i tried to come back 2000 miles later to "flush" out the old fluid thinking there was a break in, and they told me i'm wasting my money. I'll still have them change it every 20k or so for piece of mind eventhough the manual doesn't call for it.

 

Motul 90PA works the BEST. I'm talking, night and day difference. Chatter vs no chatter. And don't use additives with Motul because they don't mix well. Additives only work on other oils, like Redline and Mobil1 because the type of oil (esther based vs something else, I forget).
I've had mine since 12K miles, now just over 40K and it has become smoother than ever over the most recent 2000 miles driven. Maybe it finally broke in?
Go to Sharif for your Motul.
