powersteering fluid type

[culp71]

what was, or should be used for power steering fluid in a 'cuda with a Saginaw pump?

[Burdar]

Just regular power steering fluid...

[culp71]

mineral or synthetic?
I also hear people using ATF+4?
pro's / con's , thoughts etc.

[Strawdawg]

I would use regular.  We used to put atf in them all the time but as the power steering fluid is readily advailable, why not just use it?

[RUNCHARGER]

Synthetic may be more leakage prone.

[culp71]

kind of what I thought, ill go with synthetic.

[Strawdawg]

you want synthetic because it may leak more?

When I had my box converted to a level 3,  I asked about fluid. I'm 99% sure it was full sythetic Mercon trand fluid is what I was told. And did! I can check tonite if you like.
