Motorcraft Transmission Fluid or Royal Purple Fluid
So my pony currently has 29k miles and fast approaching the 30k mark in the upcoming months. I will be getting a transmission flush on my automatic and undecided which transmission fluid provides the best protection. Should I go with Royal Purple transmission fluid which is almost twice the cost or stick with Motorcraft Transmission fluid.
Please keep in mind that I plan on getting full transmission flushes every 30,000 miles or there about so with that in mind does it even matter if its Royal Purple or Motorcraft.
What are the benefits to using RP ATF over Motorcraft ATF?
