Im getting ready to change out all of my fluids on the FJ I wanted to change everything to synthetic and if possible run the same brand throughout the FJ...I was watching an episode of trucks and they tested royal purple and after the dyno it showed an actual Gain in power, while improving gas milage and when they checked the temp of the diffs and trans it was all running ten degrees cooler...im pretty much sold on it but just wanted to double check if anyone else has tried it and what they thought...

Thanks.
