Oil recommendations 2019 Honda Accord 2.0t

His point is that you don’t understand what is UOA.

i said the wear metals are the same, regardless of viscosity. how does that mean i don't understand a UOA? why do you have to attack people for having a different perspective than you? why the hostility?

Viscosity falls out of grade, its a 0w-16 or lower oil. The next argument, is thats fine for oil viscosity to drop?

UOA is not perspective. It is not opinion-based.
Wear metals are irrelevant. Unless your wear metals jump from 10ppm to 70ppm, which might indicate rod bearing, chain etc., it is meaningless whether it is 6ppm or 8ppm. It could be a lab error, it could be that metals are leaching differently because. different base stocks or additives, and in the end, you don't have control over exploitation during OCI.
UOA is an analysis of used oil. Not how the engine performs with that oil, but how the oil performs in that engine.
It is the biggest issue in general aviation, where owners argue with mechanics that their UOA doesn't indicate higher wear metals, while mechanics are telling them that it is irrelevant, and then, they land on HWY, which is the best-case scenario.
So, what @kschachn was telling you is that you should take advice and not try to interpret something in a way just to feel better about it.

i don't see any reason to use a 40 weight oil. 20 weight is sufficient for these engines. yet to see bad UOA on 0w20

I have several used oil analysis results showing a 40 grade is justified in my 2022 Accord 2.0T.

Wanted to get some feedback on a potential move up into the euro spec zone for my 2019 accord 2.0t 6mt with 98k on the odo. Car is stock and live in the northeast (CT) It’s my daily driver do about a 15 min commute in the am and 25 mins home to do daycare pickups. Short highway runs mixed in. Like to drive spirited at times and on the weekends and take occasional trips out to meet the family a state away.

On my 3rd oci on Valvoline Restore and Protect 5w30 after switching from Valvoline Restore and Protect 0w20 and Mobil 1 Extended Performance 0w20 the oci before that . Have been running 4-5k intervals on the Valvoline Restore and Protect.

Was looking at taking advantage of the rebates going around and trying out mobil 1 0w40 going into the summer. Was also considering esp 5w-30 as they both carry the sq approval donut. I have no issues with the Valvoline Restore and Protect other than I’m out of my stash and want to save a little bit and maybe just try something new for an oci or 2. I’ve been educating myself on the forums for the last few years about the benefits of the hths levels of the euro specs and figure why not?

Any other options I should consider?

My experience with my Accord (Also the K20c4 2.0T) is that 30 grade was borderline too thin at the end of 4500 miles, it had dropped to 8.2cSt. Now, if I wanted to really stay on top of changes, Valvoline Restore and Protect 5w-30 was proven to last and protect brilliantly for up to 5k miles. But with heavy dilution, there wasn’t enough margin for me to go any farther than that.

Since I’m unable to meaningfully alter my duty cycle, I went to 40 grade to gain margin against dilution. This far it has worked very well. There’s zero harm to a Euro 40 grade and lots of good reasons to consider one.

If I wasn’t actively testing HPL 40 grades, I’d be running Mobil 1 Euro FS 0w-40 in my car, no doubt.

Any off the shelf oil will do you well. I don't see any benefit jumping to a 40, you could safely run a 0W-30 year round.

There are several benefits to 40 grade, but the biggest one is getting out of of the “energy conserving” and ILSAC grades. These are constraints that have very subtle but real formulation penalties if you don’t want the last 0.2% of fuel economy.

 

[Hohn]

WOW A 2.0T manual Accord

Please keep it in good shape! Get rustproofing done on it so it doesn't rust! That car is a rare treasure

To answer your question though, any 5w30 or 0w30 will do

The rarest recent Accord IMO is a 2020 Sport SE with manual. They offered the manual briefly for the beginning of the 2020 model year. They are very, very rare. And finding one with leather and that coveted manual? I wonder if it actually exists as a 2020 model.

 

[Hohn]

The Honda 1.5T does have widespread fuel dilution problems because they pretend it's OK to use regular. Filling with premium drastically reduces or eliminates the fuel dilution

The 2.0T might not be as bad as the 1.5T for fuel dilution, but I still don't trust regular in a turbo

I only use v power nitro 93 octane in my 2.0T and I’ve got dilution in ample amounts.

So use it

The reasons to use the heavier oils don’t really show up on UOA, although I’ve gotten superb results with 40 grades in my Accord based on UOA results averaging 1ppm/1k miles of iron.

Here’s why I favor heavier 40 grades for my Accord:

— Dilution margin
— Less crankcase aerosol
— Possible Lower ring pack temps (thin oil in hot ring packs drive temperatures higher when asperity contact is allowed).
— MPG has improved slightly (counterintuitively, I have no explanation)
— Engine is subjectively smoother and quieter.
— Higher oil pressure at very low engine RPM where the cars tend to run
— No objective or subjective data has shown any advantage to viscosity under 40 grades for my car. The car is running the smoothest and most efficiently it ever has.

 

[Hohn]

So use it

I do. See my EXTENSIVE post history on the uses of heavier oils in the Honda K20c4.

And parts are more separated, due to higher viscosity.

most any SQ, gf-7 , 5w-30 from Walmart and change oil and filter at 5k would work just fine.

Thanks for the input everyone. I scored 10 quarts of Valvoline Extended Protection 5w30 last weekend at aitozone for 4$ a quart so just did an oil change with that. I’ll Run with that for the next two oil changes and then see what other 5w30 syn I can run.

The Valvoline Extended Protection synthetic is a good deal and a great oil, especially for $4.00 per qt just stay with it.
