Yes the 5w-30 will have better flow at startup..Quote:
Stay w/ 5w30. I haven't looked at the 40degC visc of these two, but since they're otherwise the same oil, you should pick the one w/ better flow during the first 20 min of operation in all ambient temps.
I would get a UOA. 7500 may or may not be to long for the oil your using..Quote:
The factory manual calls for 7500k OCI with the filter at every other change. I figure with running full synthetic and a high quality filter that this should be a better deal. What do you think?

You could consider seasonal 5W30 in winter, 10W30 in summer if you want to bother.

I would get a UOA done and verify the supertech is really working for 7,000mi. While the supertech full syn. has produced good wear numbers, it usually looks depleted after 5,000 miles.

I have never seen this on any Supertech Syn UOA.
I think the OP's choice sounds great. Supertech synthetic is a great bargain synthetic oil. It will definately perform better than any non-synthetic oil. His OCI is less than the mfg's recommended interval for non-syn oil so he does not need to do any UOA's.
I would stick with the 5W30 weight.
