My original post had nothing to do with silicone based fluids - simply DOT3 vs DOT4 (neither of which I have found use silicone). In my second post I believe I stated Ford said do not use silicone (which I am not). The contradiction was the SHO Times article (from the FAQ section) stated that "DOT3 and DOT4 fluid can be interchanged with no ill effects". An
article supplied by another CEG'er some months ago stated that changing from DOT3 to DOT4 was not recommended. So, which one do you believe? I believe the SHO article now because I asked Ford SVTOA and they said it was OK. I think we've beat this one to death, don't you think?
