has anyone used/mixed dexron vi with the factory dexron iii for the power steering. the castrol dexron vi bottle says it is backwards compatible with dexron iii but i cant find anyone who posted about mixing it. i need to top off my power steering and plan to flush the old out but want to make sure on the dexron vi.

This lubrizol additive seems to be discontinued. Wanted to give it a try before I swap my PS pump on my 4.8is.

There is a typical ps whine when turning the wheel at low speeds and if at full lock it makes a lot of noise.

Why did they discontinue it, was it not a good solution?

Pelican has it, but in a Mercedes bottle:

Lubrizol 6178 is a friction modifier for limited slip differentials.
