DOT5 and DOT 5.1 are NOT compatible.



I=92ve have been using Bel-Ray DOT5 SBF in my BN2 and my tri-carb since 199=
2.

I=92ve never had a problem.

"... There is a newer Glycol Ester DOT5 ..."

I think you're referring to 'DoT5.1'  I also think it was deliberately name=
d so as to confuse the issue.

Dot 4, if the car is not used regularly, needs to be flushed every couple o=
