Time to change the ATF in mu 1994 Ford Police Interceptor. Going to do the real deal---drop the pan, change the filter, drain T/C & flush cooler lines.
Now what to ATF to use? I have been happy with the Royal Purple synthetic. However, I keep being told Mercon V (a semi-synthetic) was "brewed" to address the infamous tranny shutter.
Would you choose the 100% synthetic, or the Mercon V? Royal Purple says they only carry a Mercon rating, due to licensing issues with Ford. They didn't think a "blend" could match a true synthetic. Is there something in the Mercon V that could, or does, make it superior to even a synthetic? Maybe something in the additive package, that even a true synthetic would not have?
I know the Amsoil claims a synthetic Mercon V, but it's costly. I receive R/P dealer pricing. Mercon V is fairly cheap and everywhere.Curious as to comments... Thanks!
