5w30 in my case.

How do you figure? Ultra's Viscosity @ 40*C, cSt = 61.9 and its Viscosity @ 100*C, cSt = 10.3. The Viscosity @ 40*C, cSt is slightly higher than average for 5w30 full synthetics.
If anything, it's EDGE that's closer to a 5W-20. It's Viscosity @ 40*C, cSt = 54.17 and its Viscosity @ 100*C, cSt = 9.8.
Sorry, I had a "happy typing fingers" after working a 12hr shift and accidentally typed Ultra instead of Edge when I referred to the viscosity being close to a 5w-20. Thanks for catching this.
