Royal Purple

[GT 500]

What brand of royal purple oil could you use in the shelby GT 500?
Is synchromax trans oil ok for the TR 6060?
Can purple ice be used for the rad fluid aswell as the supercharger intercooler fluid mixed in with a 50/50 solution of antifreeze?

Can anyone help with these questions?

Since I am the oil guru in these parts.....guess this is a question best suited for me.

Royal Purple suggests 10W-40 XPR in the GT500. You may have a hard time finding their XPR line of oil.

I've been doing a lot of testing using Amsoil 10W-40 in the 5.4L supercharged engine. You can read more about it at the link below.

Synchromax is also suggested by Royal Purple for your T6060 transmission. It should shift much better with it, versus the current fill of Mercon V.

Purple Ice is best suited for straight water applications, as any radiator additive is. I personally use Amsoil Dominator Coolant Boost additive in all of my applications. When I don't have any around, I will use Red Line's water wetter.
