Trolling?
I believe ATE 200 or super blue has a dry boiling point of like...530 degrees? Which other run of the mill, off the shelf DOT3 fluid does that? Valvoline synthetic DOT4 is probably the highest dry boiling point fluid available at most parts stores...and that's like 400something degrees, IIRC.
But that has nothing to do with OP's post or issue.

Or just has ADD. I got so confused to see people talk about high temp brake fluid in a thread about grinding shifts, lol.

I guess you have to define "regular brake fluid". Most brake fluids I've used are as high or higher for their dry boiling point.

Valvoline's dry boiling point is 480 compared to ATE's 536. Neither should boil in your CLUTCH line.

OK, you don't need high performance brake fluid for your clutch hydraulics. However, if you already have brake fluid lying around, or you don't feel like buying fluid just for your clutch, that you won't ever use in your brakes, then there is certainly nothing wrong with using DOT 4 high performance high boiling point fluid in your clutch.
I didn't get the impression the guy thinks using performance fluid is going to fix his shifts, but rather that known fresh fluid, properly bled, so as to rule out clutch hydraulics, was what he was going for.

It looked like new - after about 21,000 miles? Not surprising since the gearbox oil change interval is 120.000 miles or 6 years. Nothing to get it dirty, unlike the engine where combustion waste gets by the rings, etc. I changed mine last weekend at about 12,000 miles anyway since I was under the car to change the oil and it uses the same tools. And it always seems smoother when fresh. (Unlike the differential which needs two separate wrenches (23mm and 24mm?).
When I was a rookie S2000 driver (last year
) I inquired about shifting and the advice was 4300 rpm. I find it a good shift point, especially between 1 and 2.

As for the clutch fluid, it hasn't been changed since the car was built. It's time to change the fluid and in the main threads on this forum about changing the clutch fluid, everyone seemed to recommend the ATE stuff. Obviously it's not the elixir of life, but I thought it was worth going with what people seemed to have success with.
One thing... if the clutch fluid is dirty, drawing out the old stuff and putting in new stuff does help.

?? That's what I said in the first place....
This is the worst thread ever.
