2024 Civic w/NA 2.0 - Honda recommends 0w-20 - Suggestions and thoughts?

the info on these engines is all over the place. I was confused when I was buying mine. HRV 2023 2.0 n/a engine is multiport. I found information on the 2024 civic 2.0 n\a engine to say two different things. Honda news says it's a multiport system .

And the Turbo'd touring civic is Direct.

Multi-point is port injection, the name was designed to differentiate it from the TBI setup that Honda used previously.

Ok so the fuel flows over the intake valve? And that was one issue with fuel cleaners and direct port injection, is the PEA never flowed over the intake valve thus deposits would bond on the valve right?

Perfection!

So this is going to be my next commuter until I retire at around 12 years/175kmi of usage. The motor is the naturally aspirated 2.0 K20C2 variant. I planned on running the oil out until the Maintance Minder tells me to do a change out, but seems most say 7500mi max per OCI. Here are my questions:

  • What OCI should I run on the motor?
  • What oil should I run? What oil viscosity should I run? The owner's manual states 0w-20 only, as far as I can tell.
  • OEM filters Id assume? Looks like some dont like it because its a Fram?
  • Im going to dump the FF oil at about 2500mi give or take, does that sound okay?
  • I saw some people NOT resetting the MM in between OCIs... why? They would do it every other OCI to keep the MM on track?
Anything else you guys recommend, please do tell!

thanks!

PPUP or M1EP 0w20 along with a Fram ulTra synthetic filter . Run it the MM hits 15%

Its interesting how people are trying to find best oil for their car by spending so much time researching and reading all the stuff but yet do not wish to do UOA.

You have to start somewhere. This website has a lot of info and people that have been down that road already. I havent spent a lot of time researching. Just like to have conversation/talk about oil etc, hence why were here.

I agree, but at some point you realize that all the recommendations are specific to your engine and your driving habits.

Yeah not doubt. As you said, from reading and my usage it seems that 0w20 will suffice if I either change it out at 5k OCI ( if I want to be paranoid ) or 15% MM. But as you said, I should and most likely will get a UOA and see if there is dilution, but not till the 3rd OCI or so.

Correct, the fuel is sprayed into the airstream coming through the valve opening, which results in some of the fuel contacting the valve, which the cleaners in it, work to keep clean. In DI, this doesn't happen, so the valves can get carbon build-up. Some companies (like Ford) have tried to use reversion to "wash" the valves on their DI mills, but the trend now is to simply have both port and direct injection, which I believe started with Toyota, but is now also being used by Ford and other marques.

Honda recommends viscosity 0w-20, but does not require unlike other fluids.
These engines could be big fuel diluters, and 5w-30 might be more appropriate to offset the effects of lowered viscosity. I would do UOA and go from there

K20C2 is port-injected. Fuel dilution is only a problem on the 1.5 turbo

OP, just stick with 0w20 for at least the warranty period. It's an economy engine guys, no 2.0 is failing because you didn't use 5w40 or whatever. I'd dump the factory fill around 1,000 miles. Keeping that **** in there for the maintenance minder is poor advice, it's way too conservative. Most of the time when it reached 15% or so, the motor would already be down on oil.

IIRC Mazda also has a unique solution with their Skyactiv engines. They supposedly use some fancier alloys and run the valves a a very high temperature (don’t quote me but 700F is the number that stuck in my head) which apparently discourages carbon deposition.

It has been a few years since I did my reading on this and my memory is foggy on it. I don’t have time right now to dig back into it, but thought it was interesting at the time.
