Oil Change Viscosity Mistake
I just spaced at the parts store. In the stack of 5w-30 oil there was one box of SAE 30, and without noticing, I bought it. I did not realize it until after I had already poured the required 6 quarts...

You can take the advice here for what it is worth. If it was me, I would drain it out and refill with 5W-30. Then you never have to worry about it again.
As per Workhorse Manual
"Gasoline Engines
– For all temperature ranges the
preferred oil for your engine is SAE 5W-30. However,
you can use SAE 10W-30 if t
emperatures stay above 0
degrees F (18 degrees C). For heavy-duty driving in
summer temperatures, above 40 degrees F (4 Degrees
C), there can be an advantage to a single-viscosity
straight SAE 30. Refer to adjacent chart"
Ass you can see, in your driving area, the 30 weight oil provides an advantage.
