Amsoil makes a 5w-20 synthetic: http://www.amsoil.com/catalog.aspx?code=XLMQT-EA
However, I would not worry about using 0w-20. It will certainly not cause any problems. The Amsoil Group IV base stock is much better than anything by Royal Purple, and they don't add dyes or other gimmicks.

My basic problem with using Amsoil, any Amsoil (besides the fact you can't just walk into your local auto parts store and buy it) is that three months after you put it in, you get a viscosity change from what you originally bought!
Not a good thing in a modern engine where tolerances have the engineers of the engine calling for such specific viscosities.
Look at ANY independant data NOT conducted or paid for by Amsoil and they all say the same thing. That the additive package Amsoil uses for such long life accomplishes this feat by thickening the oil over time exposed to the heat of the engine.
Independant Blackstone Labs Testing has proven this time and again. One such test showed that the viscosity of Amsoil 5w-20 oil placed in a Dodge MDS Hemi Ram Truck had a measured viscosity of 5w-30 by only 6000 miles and at the end of a one year - 14,000 miles test the oil was officially classified by Blackstone to be at 15w-40! Now, lets say your '08 engine fails, oil related or not, and Chrysler measures your oil to be 15w-40 in your MDS Hemi engine. Kiss your lifetime warranty goodbye! You can bring them the empty bottle if you like, but it won't do you a bit of good.
I'm not writing this to start a debate on Amsoil, personally, I've used the product in many ATV, Boat and Truck/SUV engines, never had an oil related problem in anything I've put it in. But you people, especially those with MDS trucks and their tighter tolerances, should give the above a little thought...

]You do realize that diff weight oils DO NOT MIX???? You should not even mix diff brand oils or different kinds of oils. They may not mix properly.
Different weight oils act like oil/water in your engine. They will remain indifferent to each other the entire time they are in there together. How is this good?

So what about the rest of us with no MDS? Do we not need to be so specific on which oil to use?
