Good morning, a month ago I purchased a 2019 Honda Civic 1.0 turbo with only 18,000 km from a dealership with a 2-year warranty. The thing is, because I didn’t inform myself beforehand due to the eagerness to have a Civic that aesthetically resembles my dream car (Type R) by adding a couple of tweaks (spoiler, diffusers with exhausts, etc.), I’ve recently found out about the consequences of this small turbo engine with an oil-bathed belt. The truth is that they changed the entire belt at the dealership as a precaution, so I didn’t give it much importance. And well, after reading forums, watching videos, and such, I’ve realized that it’s not very good. I’ve only added 2,000 km more, making it 20,000 km, and ever since I found out about this, I’m not enjoying the car. It’s amazing both inside and out, but I’m very anxious, and if I had known this before, I would have looked for a 1.5. Do you think I should sell the one I have? Because it’s more headaches with paperwork and stuff.
How’s it going, friend? I wouldn’t give it much importance, it’s a good car and engine, and if they’ve already changed the belt, etc., then enjoy it. I have acquaintances who have it and are delighted, although the best ones to tell you are the users here, who are many. Happy New Year and regards.
Welcome!! 
With such low mileage and the belt recently changed, the 1.0 will last you a long time. “It’s always better to go for the 1.5,” yes, but that doesn’t mean the 1.0 isn’t a viable option. There are people who have it with 200,000 km and are still delighted and without problems.
I recommend browsing the forum a bit, you’ll see that there are practically only positive things about all the engines, regardless of the displacement.
Thank you from the bottom of my heart, happy new year. It’s true that I’m a bit anxious, the car is practically new, but well, it’s that looking at forums and opinions, videos, I always get that anxiety.
Of course, that’s it, if I had known earlier I would have gotten 1.5, thank you so much. I’m waiting for more opinions to fully convince myself because I’m really confused haha thanks.
If the car runs well and should perform like a 1.5 since it has the same chassis, suspension, transmission, steering, etc., what does it matter if it’s a 1.0 or a 1.5 if the power difference wasn’t a deal-breaker when you bought it?
In fact, the Civic 1.0 has better performance than the famous 1.8 VTEC engine that the previous generation had, which was the most powerful in the range sold in Spain, except for the Type R.
In summary, before considering the engine, you should evaluate whether the car’s dynamics and aesthetics convince you. If that’s the case and the engine works well for you, why worry about some negative comments published on social media? The 1.5 has also received negative comments due to the “oil dilution” issue, and in fact, they have had more impact and a worse image for Honda than the problems that have arisen with the 1.0. I’ve seen some videos for the American market on YouTube about mechanics that rate the 1.5 as one of the worst Civic engines in terms of reliability because of oil dilution. And of course, that’s not true, but if I believed everything I read and heard, I wouldn’t even have a car.
You should also keep in mind that the internet usually only publishes the problems the engine has.
I hope I’ve helped you. Best regards.
The truth is you really helped me, thank you from the bottom of my heart. It’s also because of what people who ask me say, that when I tell them it’s a 1.0 engine with a belt in oil, many, if not most, scoff as if it were a bad choice. In fact, many of them are mechanics, which is why it makes me doubt everything so much. I sincerely appreciate the review.
All that fame comes from the problems those engines have had, but from Stellantis, the 1.0 engine of the Civic is a close relative of the 1.0 Ecoboost that Ford uses (shared design with different final tuning by each brand). If you’ve already had the belt changed, several associated parts with new references have been replaced to precisely prevent what happened to the “pudretech”. The only thing you need to do is use the correct oil 0w20 at the intervals the car requires (even if they seem short) and change the belt every 100k or 5 years, I think it is now, with that you won’t have problems.
Thank you! The truth is that’s the fear, having to change the belt often because of particles that might jump or damage part of the turbo or something. I don’t really understand much either.
More than that, it’s because of the cause, which is the gasoline that ends up transferring to the oil because it’s something inherent to direct fuel injection. That’s why it’s important to adhere to the changes so that the belt doesn’t degrade in an unforeseen manner.
I see that you understand the subject, and I thank you from the bottom of my heart. Honestly, both you and everyone who has responded to me are amazing; it’s the first time I’ve joined a forum and the civic community, and you are all great!
I have literally had the belt of mine in my hand and I can tell you that there wasn’t a single speck of rubber in the oil or in any filter throughout the car.
Would I trust the 1.0? With my eyes closed. I drove 10,000 km with the belt tensioner broken and only noticed the noise. Neither the engine nor the belt suffered any damage. It is still running and is due for a change next year.
The belt problems in other cars are not with the belt itself, which is perfectly prepared to be bathed in oil, but with components that were not expected to be bathed (gasoline). And that is just engine design/management.
If you lack power, go ahead, go for the 1.5, but don’t change it if you’re happy with it out of fear for its reliability.
Thank you very much, I think I’ll keep it knowing that it’s not a Stellantis belt and thanks to your opinions, you are amazing.
Hello! Mine has almost 87,000 km and the belt was changed after 5 years, and it’s running perfectly, like the first day. I haven’t heard or read about any cases of belt breakage or anything, not that I’m saying they can’t happen, but it would be an exception. So, enjoy it.
Thank you very much, I feel more at ease!
Hello, I have the same one from 2019 with 130,000 km. The engine is wonderful, the belt is changed at 120,000, it’s true that it’s a bit expensive. Otherwise, you may have heard about other cars with belts in oil that cause problems, but the Honda is 100% reliable and safe. The worst thing, at least for me and from what I’ve read from many others, is the issue with the electronics in driving aids. I had problems, but with a software update, the faults were removed.
At Honda, they told me that the belt change at 6 years would cost €2,000. I suppose it might be cheaper at other workshops, but that’s exactly what bothers me. However, if it’s reliable, then I’m at ease, haha.
100% reliable? damn, that sounds bad even for a Honda 
absolutely all those with oil-bathed belts have the same problem, however, it seems that Stellantis with their “pudretech” have made a disastrous recipe between materials and design. That doesn’t mean there aren’t 1.0 Civics affected in the same way, so no, it’s not 100% reliable and safe. The 1.5 is a better option unless the other one is dirt cheap (-5000€).
The forum can be a representative example of the reliability of Honda engines. Assuming that people usually only write when they have a problem with the car, statistically on the forum, are there more threads about issues with the 1.0 or the 1.5? Because I think that even the 1.0 was sold more in Spain than the 1.5, however, it seems to me that there are more threads about issues with the 1.5 than threads about issues with the 1.0, although this may be a subjective perception of mine as I focus more on the topics opened about the mechanics of the 1.5.
It would be good to know this data if the forum admins have some type of statistical tool for open topics…
Always with the sensible opinion 
Here everything is reliable because it has to be by force
