I'm about to replace my clutch system since my throw out bearing failed and I figured I'd replace master, slave, and line while I'm at it. I've considered going back to the Castrol, but if the DOT 5 gave me years of trouble free performance... why bother? I've heard of the seal wasting issue, but my brakes have the original seals in them, and have had DOT 5 next to them for 7-8 years now. Granted the seals might need replacing soon anyway, but the DOT 5 hasn't caused any catastrophic failure. I just like the fact that it doesn't absorb water and plug the lines with rust. It also won't eat paint/epoxy off surfaces it drops on. So far I can't see any compelling reason not to use it (although I'm likely to hear some soon I imagine). Just my experience. Eric.
