Maintenance and proper use of the i-DTEC engine

Well, for me, the 40-45ºC on certain dates in Spain seem extreme hahaha…

This is fodder for another debate, in fact, it’s been discussed in the Telegram group. I just don’t trust neighborhood workshops or haven’t found one that has the specific Honda machinery and does its job well (one even left a brake pad out in my other car… yes, just like that). I pay more at an official service than at a neighborhood workshop, yes, but… it is what it is.

I have an Excel with dynamics with all the info, I’ll check it later :wink:

Yes, in the end, it’s still a business, but then you compare info with the oil guy who also tests these types of products and everyone decides for themselves.

That’s right, it seems to be our case… I’m not exactly worried, but I do have it in the back of my mind.

I’ll check it out. Not so much for the IX (although also), but for the 207 I have, which already has 350k and doesn’t move and needs an oil change… I was thinking about Liquid Moly, but I’ll look at that one. Thanks.

What I would like to try is changing the chain tensioner, the part is about €120 (a lot for a piece of metal, but oh well) and you don’t have to disassemble anything to change it, a decent mechanic should do it in half an hour easily (if not in 10 mins).

Hahaha and for my body it is. But think that the engine runs at about 90°, even if it’s 40°, that outside air still cools the engine. Of course, it cools less than if it’s 5°. And the cooling systems of a current car are oversized, prepared to keep pushing the car even if it’s 50° outside.

Diesels, especially with DPF, get very dirty, which is why it’s important, maybe every 50,000 kms. I will use it again in two changes, I think. The Liqui Moly one is like most, they’re not “bad” but for a little more you have others that are going to be more effective and safer. With one like the one I mentioned, you can really drive, but since it cleans quite a bit, it ends up removing dirt very quickly that will be in the system or clogging the filter. That’s why, with about 100kms it’s good, it gives time to clean and you don’t drive much.

By the way, what is the Telegram group you mentioned? Or is it for the Civic X? I have the IX, you know, I’m in this forum because there’s a lot of activity and it shares the 1.6 engine and some other things.

In my opinion, lacking the university master’s degree required for this topic, you are going around in circles to the point of wanting to mix oils xD. To summarize, it all depends on the climate to use the right one, you can use 0w30, 0w20, or 0w16. All of them can give you good results, but if you have that annoying noise, try lowering or switching to Honda brand oil and that’s it. Honda has a recipe like Coca-Cola’s, it’s the oil that will work best for you.

Regarding mid saps and low saps, the purists determine, no matter what, that if it has 0.8 sulfur, it cannot be called low saps. Although manufacturers say it’s a mix of 3 components and the oil you mention (l), they identify it as low saps:

And then we move on to the additives you can use with the oil to clean or change its properties… Here, no one agrees on anything on any channel. Aggressive cleaning? Bad according to some. If you do it every so often, good for others. Soft cleaning with a product in the oil used while driving, for some very poor cleaning, for others the best that doesn’t damage components… The whole additives topic, of course, without much scientific proof, just with the certainty of your feelings. :smiley:

This is what I understand…

It’s something that shouldn’t make noise. It’s said that the 1.6 should use 0w16 oil instead of 0w30, but exclusively the Honda formula (it’s like the Coca-Cola secret).

From all this, it seems that there are two people who have used 0w16 and the noise has disappeared. Everything points to the fact that being an oil, 0w16, less dense, it distributes better and faster through the conduits… but as mentioned in the video I commented on, it might be another cause, changing to 0w16 seems to be a patch apparently.

Is it bad that it makes noise? No, but it shouldn’t.

By the way, is there a change in viscosity from the 1.6 of the IX to the 1.6 of the X? Because in the manual of the X it doesn’t say anything about 0w16.

Well, that’s what I understood… so, why do they use 0w30 instead of 0w16?

They used Castrol 0w30 oil due to a commercial agreement in Spain. Now, depending on the location, they use Honda oil. From 0w30

to the famous green, which supposedly has 2 versions, 0w16 or 0w20, or both.

If you talk to Honda, they say that depending on colder or warmer climates, one or the other is used. The thing is, in Spain, the climate is very diverse.

This last one you mentioned; notice that even though it says Earth Dreams, it says i-VTEC (gasoline) underneath. I believe these are the 1.5 turbo i-VTEC (not sure about the 1.0 as well), so this oil is not suitable for the 1.6 i-DTEC.

Regarding the Honda 0w30 C2 you mentioned: [quote=“mognet, post:108, topic:4052”] Honda oil. Of 0w30

a [/quote]

this is recommended for the 2.2 i-DTEC, links were shared here with Honda Europe’s recommendations for each engine.

Talking about oil depending on the climate… Well, it’s quite outdated nowadays, especially for the official workshop to say such nonsense. That’s what the thermostat, electric fan, and so on are for… to control the engine temperatures. We are not in Dubai or Siberia, where you would indeed need to be especially careful with temperatures.

Are their trade agreements as they have told you… According to what I’ve seen in the Civic X and IX manuals, it says exactly the same about the oil topic. None literally recommend 0W16, they say to use Honda’s and if not, a 0W30 C2 (or C3 if not). The thing is that it doesn’t specify well, nor is it certain what that oil is… I doubt it’s anything special.

If you go to the website and look at all the oils, you will see that they specify if they are only for gasoline use, not in this one. You will also see this: https://www.lazada.com.ph/products/pdp-i1540828843.html?spm=a2o4l.searchlistcategory.list.89.625624d9Jnv3xn It is recommended for all Civics from 2005 onwards except the Honda CRV diesel, which must definitely use 0W-16.

Let’s see, you’re looking at a website of questionable reliability, which seems like eBay, not anything official, and on top of that, from the Philippines. Where the Hondas are not the same as in Spain/Europe. Starting with the fact that I think the Idtec are only in Europe… It doesn’t seem even remotely reliable what it says there.

Without wanting to go off-topic… I have an Accord i-DTEC and back in the day at Honda here in Madrid they used 5w30… I always used 5w30 C3 and it works well for me… I’ve never had a problem but it makes me wonder for the next service whether to use 0w30 C2… now having over 140k and with a Stage 1 done…

As you can see, what they put there doesn’t make much sense: In the Philippines, only the 1.6 idtec has been released, yet they generalize for all i-dtec and i-Cdti (a 0W16 for a diesel engine from 2003, of course… It’s something very, very rare in the 1.6 idtec from 10 years later). They talk about using C2/C3 in 0W16 when these standards, at the lowest, are in viscosities 0W30. They recommend changing every 5,000kms - 6 months… These are very different things and recommendations from those in Europe. In the Philippines, they have other standards, and those engines can easily be different.

I am the first to use that image, of that oil, to “defend” that our engine can/should use 0W16, but I clearly state that it is still not 100% reliable. Something reliable would be an analysis (or information from a more or less official sheet) that the Honda diesel oil #1 (the one that is truly recommended in Europe) is a 0W16.

WHEN USING SEMI-SYNTHETIC OIL: The oil change should be done every 6 months or 5,000 km, whichever comes first.

Specifying semi-synthetic oil in this case is not correct, as SN 0W-16 is fully synthetic.

I will give you my conclusions: As I told you, use the oil you want 0w30, 0w20, or 0w16. The green first version would be a 0w20, then it evolved to 0w16 in version 2.0. It cools better and improves consumption. It’s a full-fledged evolution that you can use or not, depending on your preferences. The standard is 0w30, from there oils evolved, and it was managed to lower while maintaining its protection. I will recommend the 0w16 because it is the one that suits best according to my experience and is what Honda currently works with.

To give you a comparison, it’s like a tire evolution. It came with the recommended Conti Premium 6, and now I put on the Conti Premium 7, which is its evolution. The brand says they are better, but since there are people like you, they continue to manufacture the 6.

I asked ChatGPT to see what it said about it:

That “Honda Diesel Oil #2.0 Fully Synthetic SN 0W‑16” you see on Lazada is not the correct oil for your Civic 1.6 i‑DTEC Euro 6b. Let me explain why:

  1. Wrong viscosity
    – The Honda Spain manual for your engine indicates 0W‑30 ACEA C2, not 0W‑16.
    – A 0W‑16 is excessively fluid for a diesel with DPF and turbocharger: it will not maintain the necessary lubricating film under load and temperature (\u003e90 °C).
  2. ACEA/API specifications
    – That 0W‑16 does not meet ACEA C2 nor is it approved for diesel engines with a particulate filter.
    – Honda only recommends “Green Diesel Oil 0W‑30 ACEA C2” (ref. 08232‑P99D‑4LHE) in Europe for your 1.6 i‑DTEC.
  3. Source of confusion
    – That 0W‑16 oil may be intended for Asian markets or for very modern gasoline engines (hybrids).
    – The listing mentions “i‑CDTi” and CR‑V diesel, but it is not the same DPF-diesel Earth Dreams that you have.

My advice

Keep using Honda Green Diesel Oil 0W‑30 ACEA C2 (bottle 08232‑P99D‑4LHE) or its generic equivalent that exactly meets that viscosity and specification. Any other viscosity, especially 0W‑16, is outside the official recommendation and may damage your engine and DPF.

Whether it’s right or wrong, I have no idea xD

You still have no certainty that it “would be” a 0W20, neither you know nor do any of us here. And as for Honda recommending that oil… Well, if you insist that it is so because it appears on a resale website from the Philippines. Look for some official reference from Honda and preferably from Europe. It wouldn’t be strange if in the Philippines those engines come without DPF or another type of post-treatment anti-pollution system. You were using the Honda Green diesel, right? I don’t remember for sure. So according to you, you continue with the previous version. Which, no matter how much you say, there is no real confirmation that it is 0W20 or anything.

Obviously, Chatgpt has no idea about this. Starting with the fact that it’s saying that the reference is 0W30 C2, either you told it that wrong or it made it up. Just with that information it has; the rest of the message makes no sense.

I told him I was using the one from the reference and the manual states that it recommends 0W-30, so I understand he made that assumption.
