Synthetic Oil choice for Rear end, T56 Tranny, and Engine

[Rickyll7]

So I did lots of searching and came up with these choices...

Rear end (4.10 frpp) - 75w90 Redline
T56 Tranny (not viper) - Royal Purple Synchromax
Engine (see sig) - 5w20 Royal Purple

Just want to get everyone's thoughts, opinions, ideas, etc.

Thanks

I know some of you must have some opinions on this subject...

How about going with Mobil1 for all three areas? You can save a little money to boot and I doubt that there are huge differences among Mobil1 and RP/Redline.

dont put Royal Purple in the engine... from what i understand is that it drags less because it sort of breaksdown and become VERY thin... too thin actually... so it doesnt protect parts... just use Castrol Syntec or Mobil1 in the motor... i like castrol better myself.

Use 75w140 for the rear. I like Mobil 1 over anything else...

So what about this:

r/p, 75w140 : rear end
r/p synchromax : tranny
mobil 1, 5w30 : engine

any thoughts?

I used Mobil 1 ATF for the tranny. Mobil 1 in the rear end too...

Royal Purple is all I use in my mustang.
Also Mobil 1 is good stuff and can be had at
your local Walmart for a decent price.

HAHA that's why I get the Mobil 1. It's like 20 bux for 5 quarts!

75W90 for the rear is just fine! I just switched mine to RP 75W90 yesterday.

I run Amsoil 5-20 and I'm changing my trans fluid over to RP Synchromax this weekend.
