I just changed mine with 116k… I put in Castrol Transmax V 75w80 and at first, I didn’t notice much… but after a few kilometers and once it warmed up… it noticeably improved… It’s also true that I changed the oil to Amsoil 0w20 and it helps a lot to notice smoothness in general… Ravenol MTF2 75w80 is also recommended… I used it with about those kilometers a couple of years ago on my Accord 2.2 i-DTEC… but I think I’ve noticed more improvement in the Civic and the quality-price ratio is better with Castrol.
If there’s one thing about Honda gearboxes, it’s that they don’t get along with anything other than the specific oil for them…

Hello! Can someone tell me which oil is needed for the transmission of the 2018 Civic 1.5? Or should the workshop where I take it know? I don’t intend to go to an official service since the one I used to go to closed and the nearest one is 80km away. Or do you think I should go to an official Honda service? Thanks
Well, that’s the first I’ve heard… of course, by sticking to the original in everything, you won’t go wrong… but damn, a gearbox failing just by using a different oil, even if it meets the specifications (of course), seems more like a fault with something else than the oil itself… there are oils and oils, of course… let’s keep our fingers crossed and I hope you’re wrong about this… 
Well, the answer is right above you… either you go with the original and you won’t go wrong, or you choose one of those two I’ve recommended, which I’ve tested and they work wonderfully for me.. by the way, Ravenol is even recommended by Honda itself (which doesn’t usually recommend much).
Keeping specifications in mind, I doubt you’ll have problems… oils are a world of their own and the original brands are not always the best option, quite the opposite in fact. There are oils that, as long as they have the same specifications as stated by the manufacturer, are of higher quality than the originals, as long as you go for quality brands like what you mentioned about Ravenoil.
Well, I just got the notification that a transmission oil change is due in 29 days. I’d like to change it myself to avoid being without my car for a few days.
Does anyone know which oil is specific to the car and where to get it?
Hi, I don’t understand how you end up asking on a forum when that’s in the manual. The manual transmission fluid is Honda MTF, and you can buy it at the parts department of workshops or in some very specific online stores, but you’ll find it by searching on Google. Some of us have also ventured to use Amsoil Synchromesh Manual Transmission Fluid, which here in Spain is imported by recambium and compralubricantes.
Well, I asked because when I’m looking for something car-related, I prefer searching directly on the forum; that way, I don’t have to go digging through a bunch of threads on other forums where I’m not registered. Just like when I figure out how to change it, where the reservoir is, and all that, I’ll post it here so if anyone else needs to do the maintenance, they don’t have to go wandering around other forums. If this is a problem, I’ll delete the message.
No, it doesn’t bother me enough that you’d need to delete it; in fact, I’ve answered what you asked for. I’m just mentioning it because before asking anywhere, the logical thing to do is spend two minutes checking the manual to see what it actually needs, and then if you have any doubts or think there might be something better we forum users can suggest, you can ask properly. It just happened to be you that I said it to, but it’s a very common habit among some users in every forum in the world. But what I really can’t wrap my head around (it’s just the way I am) is that you’re looking for information because you have maintenance coming up soon and the first (and I assume only) thing you do is ask on the forum—where someone might answer in a minute or in three months—when you have that same information less than two minutes away in the car manual.
You’ve got Castrol Transmax 75w80, which has very good reviews and a very competitive price-to-quality ratio… you also have Ravenol MTF-2 75w80, which even Honda themselves recommend, and with its additives, it could be a good choice if you really push the car… then there’s the genuine Honda oil; the price is above market value, but for the quality, you can’t go wrong… and that Amsoil one @kytos mentioned—I hadn’t considered it, but seeing the quality of their oils, I’m sure it’s not bad..
Yeah, to be honest, checking the manual is definitely the way to go, but right now I’m living away from home for work. That’s where I have my garage, all the manuals, and everything related to car maintenance. So, before I take some time off and head back home—which is when I’ll actually have time to work on the car—I’m asking around to get informed and buy what I need. That way, when I get home, I can get straight to work and not waste my vacation time looking things up, ordering stuff, or going out to buy supplies.
Genuine Honda Manual Transmission Fluid (MTF)
- Official part number: 08798-9031
That’s the old reference, the new one is 08267-999-01HE 
I understand they changed the formula and now it’s called MTF-3. Do you know the difference between that and 0826799902HE? Is it a more updated version? hahaha
I just finished changing the transmission oil; in the end, I used Castrol Transmax 75w80. I took it for a 5-minute test drive and don’t notice any difference yet.
Para cambiar el aceite he necesitado:
Four jack stands to keep the car raised and level.
A 20x24 aluminum washer to replace the one on the drain plug.
A 6x10 aluminum washer for the level screw.
It took just under 2L of oil.
The fill and drain plugs are torqued to 44Nm.
We’ll see over time if I notice any difference in the shift feel.
How’s the Amsoil been for you? It’s cheaper than Ravenol
I assume they’ll perform similarly, like with engine oil, since they’re both good brands
Curious how it compares to the Honda one
Amsoil SS performs very well; they come in gallon and quart sizes.
