Depends on whether you're intent is to keep it for the long haul - to the day it's wheels fall off, or if you're only keeping it for 5-7yrs.
I too am not fond of 5w-30 dino oils, and would choose to only run them in the cold winter months in your situation. As they tend to shear quickly, my guess is leaving behind a lot of gunk in the motor.
This gunk/sludge may not cause you problems within 5-7yrs, but if you end up keeping it for the long haul, you may or may not end up with problems.
A 10w-30 dino is less likely to shear, but does it's share as well. I'm learning the effects of that now in a vehicle ran with 10w-30 Havoline dino from 11K miles on, with every 3K OCI's.
At 143K I'm experiencing noisey hydraulic lifters - but it's important for you to know that this particular engine is known for getting clogged lifters.
We've ran Havoline dino 10w-30/10w-40 in all of our family vehicles for years with never any issues and most of them well over 150K without a blink of an eye.
If I wasn't interested in keeping this lightly ticking beast I wouldn't worry about it, but it's working on a diet of synthetic to assist in cleaning the lifters.
Aside from that, it's running GREAT - so I can't necessarily say that dino's are bad, cause they put out fantastic wear numbers.
But each engine could have it's own difference of opinion - and it's impossible for us to know what your engine's preference would be.
FWIW - If I could start over again, knowing what I know now about this one picky engine, I would've ran 5w-40 Chevron Delo synthetic or 5w-40 Rotella synthetic from the start.
