As long as your running DOT4 your fine. It has to meet a minumum standard to get that rating so any fluid rated that way will work. The valvoline stuff has always been good and its pretty cheap so go for it.

MGF hit it right on with this one. As far as the pull goes, it may or may not have to do with the brake fluid. Given that you are thinking its stock stuff after 18 years it might a cause to a bigger problem. The fluid absorbs water causing the pistons/cylinders in the caliper to rust. This creates a slow/stuck piston which gives you less braking pressure on one side causing a pull. However you could have a stuck/sticky slide from lack of lube too. Tough to say without pulling it apart.

I would suck out the brake fluid in the M/C and replace it with clean stuff and then bleed the brakes until it flows clear. Start at the pass rear and work your way up. Then clean up the caliper slides and lube them up real nice and see what happens. If your lucky it will clear up the pull for less than 10 bucks. Otherwise a set of rebuilt calipers may be needed.
