Give it a bottle of STP synth. If you add a pint, and noise continues, then it has nothing to do with grades or visc. This way, you don't waste the current fill or filter. Just make room for the pint and toss in the bottle.
The difference among some brands of grade is miniscule. 10w30 is not some automatic fix for 5w30 engines. Study the datasheets. Only a few and specific ones have a drastic enough visc/hths difference. 10w30 is just a fanboy fad bottle label by those don't have a clue concerning HTHS, SAE J300, or datasheets.
The other option is to use the ESP or Euro oils, which are 3.5+HTHS. Pennzoil, Castrol, Valvoline, and Mobil euro-choices are easy enough to find at local autoparts or walmartyr. This way, the label will still save 0w30 or 5w30 if needed. My local Napa and Oreillyauto have the Rotella T6 5w30, and local AdvanceAuto/Carquest has the Delvac1 Extreme 10w30.
The zero w thirties and five w thirties from dexos dos is a good start, even though when oil grade makes a noise, I always skip right to the common 0w40's.
I wonder how many mistake a noise from a pathetic filter too. The Napa silver/gold and Wix regular filters have caused me heartache. If its not an XP/Platinum, then you should consider upselling the customers, or use an OE filter, or stock up on Denso FTF's, or the orange can(if silicone ADBV) The XL filters, like Champ/Supertech/STP/Premiumguard/ecoguard/FVP.... are worth trying for the next service.
BTW, when I hear noisy Toyotas with 'higher' miles on them, I automatically think "IT NEEDS A VALVE ADJUSTMENT". Don't worry. When the exhaust valve burns, or any valve gets dropped, or a spring breaks, you can then address the noise.
