I have a 01 F250 PSD 4x4 auto.
Just wondering with the extra torque etc of the PSDs, if Royal Purple would work OK for the Tranny and diffs. Even if RP will work, any suggestions, experiences with another brand.
Thanks

I use redline in my 99 Durango, for the Diffs. I noticed about .5 -.8 mpg increase (pen & paper) from the same 300 mile trip. Dodge's front axles spin always so synthetic seemed like a good way to reduce already added friction on parts. No ill effects and the fluid looks as good as when I put it in, I made sure to get the proper fluid with traction modifer for the limited slip rear. I will be using it also in the rear of my T-bird once I get the motor rebuilt. Hopefully will be putting some in the X pumpkins within the next 10k. Sorry I cannot give experience from the X yet.
