Anyone running heavier oil ie 5w30?

[TNSI22]

With summer approaching and temps rising, I was curious if anyone was running a heavier grade oil such as 5w30.
I know guys ran it on the 10th gens with no issue.
Just wanting to see if anyone else has done so with the new ones.

No reason to change unless you are heavily modified and/or tracking the car. Street driving, even spiritedly, will never reach dangerous oil/coolant temps.

I'm running 0W30 in mine during East coast Australian winter (not very cold). Will likely go up to 5w30 when it's summer.
I've been sending used engine oil samples for testing and they seemed to be all good bar the first oil change which showed a high level of fuel content which thinned out the oil quite significantly evident in the viscosity tests. Something to keep an eye on cause our cars run fairly rich at WOT above 4K rpm.

If you’re really worried and want better oil with the same weight, just grab some Amsoil 0w-20 or torco SR-1. Both are better than OEM and protect the engine more. Buddy of mine ran Amsoil 0w-20 on his W1 FBO 10th gen si without an issue.

You'll find 5W-30 is fine per the European owners manual. Search Honda UK to find it. Engine internals are the same, regardless of location.
Only reason 0W-20 is spec'd here is for CAFE fuel economy. 5W-30 provides a superior film thickness, especially for high loads, which these engines are capable of.

5W-30 is a great option for you if you are in the Memphis, TN area.

I use 5w-30 in mine during winter and bumping up to 10W-30 for summer but its hot here in Florida.

I am running ester based 5W-30 (Redline brand). Haven’t sent any samples for testing but the car has been running fine and I check the oil regularly. Personally I think it’s the best to use for better internal protection for track driving.

I've got one oil change left on my Honda Servicepass, after that I'll be switching exclusively to Red Line 5W-30. The 0W-20 was mandated mainly for fuel economy standards.

I used Pennzoil Synthetic 5W-30 in my 2018 Turbo Hatch with no problems. Definitely engine was quieter.
I choose the Pennzoil because the viscosity is at the lower range of the 30 oil weight for viscosity and the great oil analysis.

Here in central florida used 0w-20 until i started modifying and then went 05w-30

My SI is FBO, I have been running motul 5w40 for the past few oil changes. I have not had any issues with it, and actually it quieted down the racket that a stock Honda engine tends to make quite a bit.

I'm running 5w30

i think i'm going to switch my Si to 5w-30. i drive the hell out of it and want it to last 300k miles.

I run 5w30. It's required for the turbo I have installed.
