Recommended Power Steering Fluid
I have a 1990 ZR1. OEM recommended power steering fluid is no longer available. What is the best replacement PS fluid for our ZR1s?

1994 Corvette owners manual specifies AcDelco 12345866 or 12345867 - different size containers.
Both available at Amazon, summit racing, etc. |

Re: Recommended Power Steering Fluid
I never used a stock fluid in '95 #140. In fact, I used that in any GM power steering system from 1988 until installed electric power steering on C7. I, also, wouldn't use a fluid spec'ed in the mid-90s because what's available today are far better choices.
I used Red Line Power Steering fluid which is an ester-based synthetic fluid and a far better choice than the petroleum-based fluids recommended back then or now. If you don't like Red Line, Driven Racing Oil markets an mPAO-based synthetic fluid, "PSF" which is almost as good as the Red Line Oil product.
