So leaving in old RBF600 may (and I emphasize MAY) be worse than new DOT3. But mixing DOT3, 4, and 5.1 is not like mixing those with DOT5. DOT5 can only be used with DOT5. The fluids cannot be mixed.
I agree with you....if going to the track, shortcuts are never good.

thanks for the explaination.
We (wife and I) just do a full brake/clutch fluid flush every 6 months with RBF 600, I prefer to be safe than sorry, even if it is a bit of overkill.

/\ sounds like you had fun. I'm sure as you get faster, your oil temps will correspondingly go up a bit.
