All it means is you'll be reaching normal operating temps.
I'd still leave in the quality 20 wt. It's to bad you don't have an oil temp gauge, but if you sense the oil may be getting hot simply avoid using WOT and you'll be fine.
Why would you want an oil that you may have to "drive around". Having to limit wide open use is not my idea of a good oil.
You are missing the point:
1, The PP 5W-20 wasn't the chosen fill.
2, The OP wanted to know if he could live with the lighter fill.
3, Without an oil temp gauge he has no idea if it happens to
be better or worse than the 5W-30.
( This BTW applies to most everyone who wants to "fine tune"
their viscosity selection to their application).
4, Suggesting he avoid WOT if the engine gets very hot was
to put the OP's mind at rest. ( Most average drivers
rarely use WOT anyway).
The point was, why would you want to live with that little of a safety margin? If I can't beat it to death in any temperature, I'm going to find a better/thicker oil.
Good thing you're not the OP ..or he'd already be on his 3rd refresh on the engine due to beating it to death with heavier oils
