So would I, but it's been that way every time I've gone from an Xw-30 to Xw-20 in the Honda (QS 5w-30 and two rounds of M1 0w-30). It's unnoticeable on the highway, but in the city there is a change in feel.
My shifting sucked when going to the 30. I rev match, and the rpm dropped more quickly with the thicker oil so that I had to make a conscious effort to shift more quickly or blip the gas sooner. This was less pronounced as the engine warmed up.
On the other hand, the engine was a heck of a lot quieter above 4,000 rpm at WOT when warm. That's one reason I tried the 0w-30 a second time. I definitely don't beat on my car. But sometimes I'll go WOT to pass someone or avoid death on a freeway merge. The engine sounds a bit like a motorcycle with 0w-20 and 5w-20 at higher rpms, and it sounded like a car with the heavier stuff.
I dunno. Maybe I was misunderstanding the whole 0w concept, as it seems it doesn't make much of a difference if you don't live on Hoth. I've seen posts where people got flamed for calling an oil "free-revving." But that's what the lighter grades feel like in my Civic.
Free-revving, responsive, louder-at-high-rpm, etc.: M1 0w-20, Pennz YB 5w-20, PP 5w-20, QS 5w-20 (dealer bulk).
Tight, muted, measured, quieter-at-high-rpm, etc.: M1 0w-30, QS 5w-30.
I guess I'm at the end of the viscosity experimentation phase on the Honda. Now I get to obsess about the brand of oil instead. By the time I'm ready to drop the current fill maybe the engine will have worn in enough for the UOA phase to start.
