ok well ive done a lot of searching on here and there is a lot of info on diff fluid but what weight diff oil should i buy i am in the air between amsoil and redline, also i do not track the car but i do daily drive it and am a lil hard on it. It is an 02 with 13 k miles and i just purchased it and figured i would change the fluids also what is the recommended weight of the trans oil? Or royal purple products because i did use them in my rsx-s for the tranny and was pretty happy with the results. thx for the help

 

Of the ones you mention, I'd say AMSOIL SVG 75W110 is the ticket. If you want another great option, try LE 1605. It is a SAE 110 GL5 and can be bought by the quart from Rick's Signature Accessories. You will only need one quart for each servicing.

 

or you can look at Hardtopguy.com

 

I use Amsoil MTF. For me, it's slightly smoother than the new Honda MTF. But most just use the Honda MTF.

 

mobil1 75w-90 for diff

GM friction modified syncromesh for MTF, can be bought from hardtopguy in AC Delco version.

 

Red Line 75 W 90 GL-5

 

Motul 75w90, but next change will be to http://www.ricks2k.com/products/le1605.php

 

It's 75W85 GL4 gear oil, or you can use SAE 10W30 motor oil in a pinch. It's the same weight, but without the tranny/gear oil additives.l

 

Amsoil is the ticket alright
was using Motul didn't like it so i went with amsoil luv it
Amsoil MTF Tranny 2 bottles
Amsoil SVT 75w-110 Diff 1 bottle

 

How often are u supposed to change diff oil? I purchased the car used and not sure when was the last time the previous owner changed. Same with transmission oil.
