The clicking noise you hear at low RPM is the fuel injectors. they are solenoid valves that open and close. The clicking to the back seat when closing. If you increase the engine rpm the frequency increases and it is less noticeable. It is also more predominate on cold starts. If this bothers you you can add an upper cylinder lubricant to you Fuel tank. Lucas Amsoil and Redline all make them. Personally I use Marvel Mystery oil in My 2018 Limited. Use 4 ounces per 10 gallons. So 9 ounces per tank. You will notice a difference. You can buy a 1 gallon jug at Walmart for around $18.

0w-20 is for CAFE. In other parts of the world our engines can use oils up to 20w-50 depending on expected temperatures.
I got hold of the 2015 Australia recommended oils page awhile back. Chart is actually for the FJ.
The Middle East is different still, sorry don't have the chart.
15w-40 down to -12C / 10F
10w-30 down to -18C / 0F
5w-30 for 10C / 50F or LESS
I am currently running 5w-30 with zero issues and will be trying some 5w-40 and 15w-40 down the road a bit.
I'm running a 30 weight as well and the engine is smooth as butter! Did you ever run a 40 weight?

I've never used Marvel, how does it compare with the Lucas? Running Lucas every fill up, so far so good.
Not yet! 5w-40 is slated for the next change though.

I’ve used both. They both improve gas mileage a little but Marvel does a better job keeping your engine clean. I watched a video on YouTube where this guy tested multiple engine cleaners such as Chevron Techron, Lucas and Marvel and Marvel came out on top but Lucas also did well. My personal opinion is Lucas seem to improve gas mileage a bit more but Marvel will keep your engine a little cleaner. Both are good.

Marvel mystery Oil is primarily Naptha with some additives, It has been around longtime, I remember my grandfather using it crank case , motor oil back then was not multi weight and would often cause hydraulic lifters stick . Naptha has some serious detergent qualities so this will clean injectors as well
Lucas is a refined petroleum product like Marvel more similar to 2 stroke fuel additives. You will notice some viscosity when pouring into fuel tank. I like Lucas Products; but since NASCAR affiliation the stuff got kind of expensive. Here in MD like $34 per gallon at Walmart.
So I find MMO to due a great job at a better price. Longtimeengr

I have a 2020 4Runner with 43k miles and it makes a weird noise while accelerating while it's cold too. Like it's fluttering or wings are flapping. Once the engine is warm, the noise goes away when accelerating.

We have a 2014 with 369K miles on it. I have tinnitus and can no longer hear the turn signal click, so wife is constantly telling me to turn it off. I say what noise in the engine?
Use Valvoline Restore and Protect 0w20. Nothing better. Toyota oil loaded with moly does nothing.

The 4.0 is just a noisy engine. Check out "The Car Care Nut" on You*ube, he's a Toyota mechanic with his own shop.
Overseas the 4.0 is approved for up to 20w50, I'm currently using 5w30 and it has quieted down a lot. (this is in the 2013 FJ, same engine, but I also used 30 in the 2015 'Runner I had with similar results)

I have a '23 Limited I bought new last September. Did the first two oil changes at 500 and 1000 miles using Toyota 0w-20, engine had a slight valve train tick more so than my other cars but not too big a deal. The next two changes I switched to Amsoil Signature 5w-30 and it quieted right down, now all I hear are the injectors firing at 11k miles. It's probably still breaking in so this might change over time.

Hi guys, I recently did a head gasket job on my 99 4 runner. It costed me an arm and a leg took it to a shop that works on 3rd gen 4 runners, Once I got the car back I noticed a ticking sounds almost like the car now sounds like a diesel. The
You're in the 5th gen 4Runner section, you may have better luck posting in the 3rd gen 4Runner section.
That said, without hearing your engine running, the cause of the noise is just guessing.
I'd say your best recourse is to take it back to the shop which did the work, for diagnoses and repair.
