You are both confused. The best fluid for Girling brake and clutch systems, which is what your DeLorean has, is Castrol GT-LMA. Castrol is by far the friendliest fluid for the rubber compounds that Girling uses. All other fluids, regardless of DOT classification will cause seal failures within 6-12 months. This is not limited just to DeLoreans, the Lotus guys have the same experience. -- Mike -------------- Original message from "Charlesdos Mavor" <charlesmajor@xxxxxxxxxxx>: -------------- > > OK, > This is the smartest bunch of folks on the net so here it is.
