2012 civic here with with crazy oil consumption. I used lique molly engine flush before I changed oil, but it did nothing. I have looked in the cylinder with an inspection camera and the top of the pistons
are covered in thick carbon. The threads on the sparkpluggs have oil on them, but that oil is fresh. Would to much blow by thru the pistonrings really cause oil on the threads?
Has anyone tried an pistonsoak? I have ordered some b12 chemtool and are gona do an soak.

 

Use 5W30 or 5W40 instead

 

Hi all i have the 62 plate honda civic 1.8 petrol auto registered january 2013 will this model year also be affected with the oil burning issues or is it just the MY12 models

 

Your motor (probably, maybe) is affected if the serial number of the motor is below R18Z4-1030320. You can find the number somewhere on or around the engine.

The only way to be sure is to remove a spark plug and film the inside with an endoscopic camera. If there's R3A stamped on the top of the pistons, it's bad. If it's R1A, it's good.

At least some of the Civics MY2013 are affected because I own one from 06/2013 and we're having problems.

 

Hello thanks for the quick reply it says
my engine number R18Z41014xxxx on the log book

You can also check the VIN and see If the 10th letter is "C".

The serial number doesn't look good. Keep an eye on the oil consumption and pray.

 

When I bought my MY13 I had to wait till March 2013 to get it

The easiest way to confirm is the 10th letter of the VIN

Other ways to quickly check is, are your front seat front bolts exposed

 

Hi i have the vin with the letter C so i guess i have a oil burner too

 

I don't know if ya'll know but at least on the german Honda website you can check your VIN (after creating an account) and it will say in what year your Civic was manufactured. And although mine was registered in 06/2013, it says it was built in 2012.

So it actually may be that only 2012 models are affected but some of them were registered in 2013.

Cheers.

 

You can contact Honda online and they can tell you exactly when your car was built.
To be honest my 2010 8th gen was an oil burner too, 250ml / 1000km which is a lot (for a Honda) with regular driving style.

 

I only do around 6k miles a year so im not sure if i should be too bothered or just top up and drive not even sure if it burns oil,all i can say is engine oil smells of fuel but then the car was sat for 6 months with last owner before i bought it, needs a oil and filter change soon then ill see if this car burn oil or not..

 

If you are getting low oil warning on the dash, then you definitely need to top up regardless of how many miles you are driving

 

I'm a bit late to the party. My 2012 Civic has been eating a bit more oil that it should since the beginning (bought it at 70k km), but I was not paying enough attention to that (first car). Now at 130k km, it takes roughly 1l for each 2000km. So the oil cans started piling up in the trunk and I can't be overlooking the problem anymore (haha). Any experience how bad can it get? It does not seem to make sense to me to invest into a repair of such an old car.

Anyway, I wanted to thank everybody for sharing information here, it's been very helpful!

 

Go up in viscosity 5W40, still in specifications of Honda and climate in The Netherlands. You can even try 10W40.

 

Sold... good bye honda ,,hello mazda ✌👍

 

What Mazda engine, tell me it is not Skyactive diesel

 

Haha why would i get a diesel ..

 

I hope it's not a Mazda 2.2 diesel - terrible engines

 

2.0 skyactiv G petrol auto Way better then these alien civics ADIOS 👍😂

 

I think you did a good job

 

Another 9th gen 2012 Civic owner. Bought this car on August last year for 7.000€ and 212.000 kms (Spain). I've tried everything but nothing worked. My engine is between those affected engines. I was really excited when I bought the Civic because it was the car of my dreams but when I discovered the excessive oil consumption on this forum the nightmare just became.

I thought about keeping the car and topping up with oil every now and then but my car also have a check engine light. That light is the PD0420 code, which means "Catalytic converter system, bank 1 - efficiency below threshold".

Catalyst System Efficiency below Threshold

As I've read on other forums, I wonder the catalytic converter is affected by the lost oil. That made me always be worried because I couldn't keep a car which might be damaged at any point. It's such a pity because the car works great, but it already has +220.000 km and it would'nt be a good idea.

I think I'm selling it next week to a dealer, even if I'll lose a good amount of money.

The good thing is that I found an Accord VII 2004 2.0, 160.000 km, in an excellent condition. What a great and reliable car! It's funny how I needed to go back to a well built car in order to maintain my mental peace.

In short: if you own a 2012 Honda Civic, you should get rid of it as soon as you can.

 

I wonder the catalytic converter is affected by the lost oi

Yes and O2 sensors fail too

 

Does this affect the FK1 1.4L? Or is it just a 1.8L engine/piston issue?

 

Another Civic owner here. Bought a 1.8 model from 2012 with 95.000 km in the begining of the year. I paid 11.000€ (in Portugal cars are very expensive) It has been consuming around 1L per 1000km. I dont know what to do. I dont like having to add oil every month but I dont want to scam a person and selling the car saying everything its okay. I could sell it an assume the problem but that way I would lose a lot of money and I would rather lose that money on fixing the problem.

Changing the pistons and everything that needs to be changed will solve the problem forever or the problem will eventually return?

Every other part of the car is impeccable. Is it worth fixing?

 

Since the car is only 95k km it might be doing the fix, but in my case when I bought car it already has 170k km, I just use thicker oil (from 0w20 to 5w30) and its burning about 3 litre every 10k so thats fine for me

 

Bought a 2012 civic for €6500, 112k km and burns about 200-250ml 5w30 per 1000km over last 5000 km.

If I was first or second owner and got this after few years I would be furious, but at this price and consumption levels I think it's simpler and cheaper to keep topping up oil than new pistons (€800 + labor). Total replacement cost is 400k km of oil. I live in northern europe as well so the body will die from rust before the engine.

2014+ models are already €2000 more expensive so it's almost like it is priced in. And newer 10th gen civics have oil dilution + wet timing belt problems.

As mentioned previously in this thread, in the manual it says that up to 1L/1000km is okay and no warranty. Let's hope this line wasn't written only by lawyers and that they got input from engineers who worked on the catalytic converter and spark plugs 😂😂😂

 

That’s better than my 2012 I’m burning twice that plus I’m using 10w40. I’m 50/50 on getting an engine swap for a later model used engine but it is going to run me £1k just for an engine without labour costs. Still looking for a garage to quote for piston and rings. Now do I just cut my loses and trade it in or fix it this is the dilemma we all face.
