When I moved to Colorado 5 years ago I had DOT5 in my roadster, I soon
discovered that I could not get dot 5 anywhere. Napa stocked a pint or two
at $15, when faced with a $60 bill for a flush and the probability of not
being able to find it I switched. If you run DOT5 make sure you can get it
readily.
Also DOT5 is a smaller molecule and so it will find places to leak from that
DOT4 won't.
I had no problems in the 4 years that I used it but these are important
factors to consider.
