I use Prestone DOT4. So does Ranger, so it must be a good thing.

In fall 2007 GM revised the specification for all Corvette's with hydraulic clutches to DOT4 fluid, instead of DOT3. That includes all C6s, C5s and C4s.
Suggest start using DOT4. There are many good brands. Prestone DOT4 is one of them. Readily available, including Walmart where the price is $2.60 for a 12 ounce can. That's 1/5 the price per-ounce of the GM brand. They perform about the same in my testing.
