[CU2] Excessive oil consumption
I was wondering if anyone else has had an oil hungry Euro?
Mine is brand new and between 1000 km and 8000 km it consumed almost exactly 2 litres of oil. Took it to the dealer to check it out and got the 6 month service at the same time (i.e. a $260 oil change), and no explanation, but it is now on "consumption watch", which means taking it back every 1000 km for 5000 km, so they can check the oil level. Somewhat inconvenient.
Has anyone else had to do this?
outcome from the 'oil consumption monitoring' ?
Folks, was wondering what the outcome was for those undergoing the "oil consumption watch" exercise ?
Sorry to revive an oil thread, but I've recently discovered my 2012 CU2 is consuming oil, to the point where i've already had the oil pressure warning light come up before the car even hit the 5,000km mark. When i measured it, there was barely enough oil to touch the end of the dipstick.
I owned a 2007 CL9 Euro for 5 years (drove it for 78,000km), and it didn't lose a drop of oil whilst i had it.
my engine has just been replaced by Honda....
Folks,
I’ve just had the engine replaced by Honda in my 2012 Manual Lux Euro. (is this a first for any Australian Euro ??)
In short, my engine was a lemon from the moment is was manufactured.
To provide some history to this, my car had to be towed in March 2013 at 4,600km due to insufficient oil in the engine.
(yes, a very sad day for my 5 month old $40,000 vehicle)
The oil consumption tests then commenced. It soon became apparent the oil consumption was getting worse. The exhaust tips were full of thick carbon residue.
I would check the oil level myself and noticed the oil was as black as tar on the dipstick. Not only did it look burnt, it actually smelt burnt.
When the car had 7300km on the odo, i brought it in for its routine 1000km check.
It required 1.3 litres of oil to bring it back to level.
Given the severity of the oil consumption, i was expecting Honda Australia at this point to begin some form of remediation, but they wanted me to continue for another 1000km of driving. <insert expletives here>
So it was topped it up with oil, but the car only survived 600km of driving after this.
My all-time favourite warning light appeared (the Oil Pressure light) due to lack of oil.
The vehicle was then towed back to the Service Dept, where it sat on a hoist for 5 weeks in total. Lets just say they didn't bother to even measure how much oil it had gone through, as this event marked the official end to their consumption tests.
The first 2 weeks were spent disassembling the engine. Initially they were planning on only replacing the piston rings and valve stems, however they continued to disassemble the engine to discover the cylinder walls were ‘scored’ (ie… scratched)
A replacement engine known as a “Short Block” was then ordered and installed, which is basically the bottom section of the engine block containing the pistons etc.
The existing engine head was sent away to a 3rd party head specialist, who refit the engine stem seals using a micrometer and other fancy tools.
I only just picked up the car last week from the Service dept, so i can't comment on whether it has corrected the issue, but i would assume the manufacture issue has since been sorted out in the Honda factory. Fingers crossed...
The cause of all the oil burning was discovered to be faulty Oil Control Rings, which I had confirmation were not installed correctly at the time of manufacture in the factory. The wrong amount of torque was applied, which caused them to spin around, when they aren't supposed to. These were also were responsible for damaging the cylinder walls.
I believe what we have here is a simply a bad batch of motors. The vehicles that appear to be affected are a small set of 2012 Manual Euros.
Including my Euro, I'm aware of 3 other people with vehicles exhibiting this issue, and they are all recent (2012) manuals. (one of them is in Canberra and isn't an OzHonda member, but i tracked them down and have personally spoken to them to confirm their model/year details). Ah, the wonders of the internet :)
Prior to this vehicle, i owned a 2007 Euro (CL9 Manual Lux) from new, which i drove for 78,000km, which didn't consume a single drop of oil during its 5 years of me owing it.
For those interested, there are threads on TSX forums about their 2012 manuals having the exact same issues as us (our Euro is known in the states as the "Acura TSX").
Anyways, i hope this info helps some owners who may be going through the same thing...
