MODERATOR MESSAGE: There have been several very long, rambling Topics about the issue of Oil Dilution in newer CR-Vs on the CRVOC. (Primarily the Turbos, but to a lesser extent, the Normally Aspirated cars also.)



We have attempted to focus responses to the issue HERE, and effectin this Topic. The LINKS in the post below discuss various aspects, like the amount of oil gain, the causes, how to check the orange dipstick, and how to advise Honda Motor that the issue is SERIOUS.



If any related new Topics are created, we will either close them or merge them into this one.

Yes, we should all be checking our oil fairly frequently. The owner's manual says to check it every time you refuel. However, if you're like many people, the interval is probably longer, if you even check it at all between oil changes.Here are a number of threads on this forum about this issue. Be warned, some of these threads have gone down rabbit holes of arguing over how to check your oil and/or what higher octane gas does or does not do:There is also a FaceBook group where there is discussion of this issue, if you are so inclined:Here is my story:We have a 2017 CR-V Touring. It is the fourth Honda car that we have owned; it replaced a 2008 Odyssey that we happily drove for 252,000 miles. We still have an '05 CR-V and an '06 Civic (both over 200,000 miles), and I also have a Honda motorcycle, if that gives you any insight into my opinion on Honda vehicles.The '17 CR-V is my wife's primary vehicle. She has an 80 mile round trip commute to work every day, and has an aging mother with health problems that she goes to see weekly, adding another 240 mile round trip. We put a lot of highway miles on this car. We've had it just over a year, and have over 31,000 miles on it.I do all my own maintenance on my vehicles. I enjoy it, and I generally distrust dealers and service shops. On the '17 CR-V, I have done two previous oil changes, in July and November of 2017. They were unremarkable.I performed the B-1-2 (oil/filter change, tire rotation, cabin and engine air filter replacement) service on 03/13/2018. This time, when draining the engine oil, the oil was VERY thin/watery and splashed everywhere. I've never seen anything like it, and I've done many dozens of oil changes--probably hundreds. The oil smelled strongly of gasoline, and more fluid than expected drained out of the oil pan.After finding the above threads describing this issue, on 03/15/2018 I had Brookdale Honda in Brooklyn Center, MN look into it. I had a preexisting appointment to have several software updates done and some tire noise checked into. I brought them my used oil filter (which contained some of the diluted oil). They confirmed the oil smelled excessively like gasoline. They contacted the Honda TechLine engineers and were told that Honda is aware of the problem, but there is no fix at this time. The only suggestion is to closely monitor the oil level, and if it increases (presumably due to gasoline dilution), to change the oil.Some reports on the forums state that using premium gasoline has reduced the problem. Many reports state that the issue is associated with cold weather, so the problem may be less pronounced during the summer months. The first two oil changes I performed in July and November 2017, I did not notice this issue, so this may be true. However, others on the forums that live in warm weather states are reporting the issue as well. Some have also reported being told to drive in "S" mode until the vehicle is fully warmed up, to speed the warm-up process and hopefully reduce the issue.The service advisor at Brookdale Honda speculated that Honda will eventually issue a powertrain warranty extension and apply whatever fix they come up with for free, but that is pure speculation on his part. Unknown ETA of any kind of fix at this time, and who knows how Honda will address the issue. This 1.5L turbo engine is used in the Civic as well, so they are installing it in two of their best selling vehicles. One would assume it is in their best interests to make this right.We are now looking at purchasing a Honda Care extended warranty because of this issue. The oil that I drained from the car had almost no viscosity. It was literally like draining water out of the crankcase. I am very concerned about what kind of damage has already been done to the engine at this point, even though it appears to be running fine, and I have had no check engine lights, etc. Whatever damage may have been done may not manifest itself until later in the car's life.Again, Honda's only advice at this time is to closely monitor you engine oil level, and watch for any increase. I would also encourage you to smell your oil to check for a pronounced odor of gasoline.Please be aware of this potential issue! I am sure there are more cases of this that are going undetected until a failure of some kind happens. Don't let it happen to your car. Check your oil!Here is a link to a redacted copy of my service paperwork. Note "Job #4" at the bottom of page 1 and top of page 2. https://1drv.ms/b/s!AtZBj0rDJFy5vHCkQG_5nnG_2-Kk EDIT: Found this today:Honda is recalling Civics and CR-Vs in China for this exact issue. Apparently, public pressure forces them to respond. The issue there is being described as related to cold weather.EDIT (thanks Kimbo80!):The Chinese government rejected Honda's original plan to simply recall the vehicles, saying that Honda's plan was 'not enough.' They implied that Honda should consider extending the factory warranty, and Honda has subsequently agreed to halt sales of the CR-V altogether, and may have to halt sales of the Civic as well.EDIT (thanks RAV4owner for pointing it out, and thanks raigen18 for posting):Honda Canada sent a notice to its dealers on Feb 28, 2018 regarding this issue (specifically the misfire/oil pressure warning light that it can cause), and asked them to continue to report the issue to help them with their investigation. They also state that for those misfire/warning light cases, they can do an oil/filter change and charge Honda for it.A screenshot of this notice is attached to this post.EDIT 10-05-2018: Consumers Reports article:EDIT 10-10-2018: Changed the Title to better reflect the information contained.EDIT 10-27-2018: Here are links to Honda's TSBs (Technical Service Bulletins) for resolution of the heat and oil issues.
