0w20/30 in 5w20/30 engine?

Thinner oil might improve MPG a small amount but there's more risk of failure under heavy loads and high temps, especially if it's a worn engine.
Stick with the recommended grade, and the best oil is whichever one meets all the specs and is on sale. Spend more on better stuff if it helps you sleep better, that's why I use Redline!

nothing.
Typically a better base stock. Cold temp starting is a major positive factor, with a little faster oil flow through the engine according to oil producers.

Actually this is not true. 0wt oils are designed to flow faster but there is no loss in protection.

So I have people here saying 0w is better and some saying not to go lower?!? Idk what to do! Lol. Ultimately I'm trying to quiet a noisy Kia Forte motor down. It's the 2.0 and is a little noisy at idle. I am currently running QSUD 5w30 but it's still noisy. I wasn't sure if any oil will help?

It's not the oil it's the way your engine is designed.

Have you tried using Pennzoil Platinum ?

No. I haven't tried anything other than QSUD and bulk conventional 5w30 for quick shop changes. The car has 68k on it so it's not under warranty anymore because we aren't the original owner. Ultimately I guess my new question is, what would be the best oil to run it it. Whether it's conventional or synthetic? Preferably a synthetic since it can go longer before changing (she's tends to not pay attention to when it needs changing)

Im not sure there are cold start advantages at -17C. Do we have MEASURED KV or cP at this temp. NO Extrapolated data please - It's not valid at these temps.
I see NO numbers here; So no support or validity to opinions expressed. 0-Winter just means a 5 or 7 deg colder pumpability over 5w or same degree of improvement of cold temp performance before cloud point or gelling of the lubricant. 99.99 of you here willnot test these waters whatsoever. 0-winter multigrades are NOT specified by SAE or API or ILSAC for cold performance analysis at any point above minus 35 and minus 40 degC. other than that: used, aged fluid loss of pumpability shall not worsen more than one winter grade. Said again; a 5w-xx shall not degrade past the 10w-xx as a used oil.

A lot depends on SPECIFIC product. You cannot generalize the fine points. I find Valvoline 0w20 is an exceedingly fine 0w20 for the price. I will find out if their 5w20 works as well for summer, as a 0w is not needed at ambient temps > 20 below zero F.
