That's a good deal, regardless of oil used. Don't sweat the use of conventional oil. Guys use 15w40 year round up here and their trucks long rot away before the engine wears out.
Everything you state is fair, but..........
The manual does mention using 5W40 when the anticipated temperature range will be at or below 0*F.
