going to be changing my diff fluid tomorrow..

i hear it calls for a gl5 or gl6 90weight?

is that right..

also.. how much oil do i use? so i know how much to buy

and is that what i should get or maybe somethign different?

i will be changing it at school, so the NAPA store in the school has to carry whatever i need to use.

thanks for the help

You need about 0.8 qt., so 1 bottle. There is no GL-6 fluid anymore. You can use a SAE 90 fluid, if you can find it or you can go with LE 607 as sold in the forum store or Hardtopguy. Or you can use any GL-5 multigrade that covers 75W90.
As for how much exactly to put in, you fill it till it comes out the fill hole when the car is on level ground.
There's a thread in the FAQs at the top of UTH with pics to show the whole procedure.

 

alright, thanks alot!

looking forward to changing it tomorrow.

maybe ill do my tranny fluid as well. the corse im in right now is undercar.. adn we can do whatever we want.. so might as well get it done while i have the oppertunity.

thanks

I'm very happy with Redline 75W90.

 

my 10k floam UOA should be here any day. I am expecting excellent results.

 

Mobil1 75-W90 in the silver bottle is available all over the place, and highly recommended.

 

LE 607 for me.

 

lol

 

My top picks, in order:

1) LE-607 (no winter, above freezing only)
2) Mobil 1 75W-90 (all-season)
3) Redline 75W-90 (all-season)
