Gas leaking into oil?

Just read the latest copy of CR(Feb 2019) and they say that a lot of Honda CR-V owners with the 1.5T engine have reported gasoline leaking into their oil. Honda says that this is mainly caused in vehicles driven in very cold climates although no information on exactly what is causing this was provided. They did not mention the Honda 2.0T, or anything to do with Acura but thought I would post this as a heads up. Gasoline in the oil is bad news.

Thanks, but this is VERY old news has has been all over the Internet for quote sometime including this forum. Honda has a "software" fix for the 1.5T to help it get up to operating temp quicker which has also been documented to work well. We'll see if that "fixes" the OD issues but there has never been formal mention of the 2.0 having this same issue that I am aware of then a few folks claiming they are experiencing the same with their engines.

Ironically, I didn't have any oil dilution issues with the 1.5T in my 2017 Civic, but both my 2018 Accord and 2019 RDX with the 2.0T started smelling like gasoline under the hood and occasionally in the cabin at around the 3,500-mile mark.

Gas smell in cab

glad I found this post. I have a 2019 rdx and when you get in it after itís been driven it smells like gas in the interior of the
car. So? This is a known issue ?

Yup, a well known issue; have your dealer try the software patch to see if that cures the issue.

thanks.
Called the dealer and talked to the service department to make an appointment and of course they have never heard of this issue. Going to bring it in next Saturday.

Search around this and other Honda/Acura sites, I'm pretty sure you can come up with the TSB on the issue.

It is? Please list some references. I've only seen one post on this forum regarding it.

Are you associating this with the 1.5l turbo in the CR-V/Civic?

Sorry, my bad, I thought you had the 1.5T in your car.

No, not the same engine at all.

Question, do you do lots of short trips in your car?

doing some reading sounds the the direct injection portion is the same. Most of the cars driving is highway trips but there
isntje odd short trip down to town. My Wife got home
from work the other night after a 40 km highway drive and I went out 15 mins after she got home and it smelled like someone poured gas in the Interior.

All direct injection engines will have some gas getting into the oil. Honda's 1.5l Turbo has been known to be worse than others. The 2.0l Turbo in the RDX has not had the same complaints, to date. This was one of the reasons I joined this forum. I wanted to see if this issue was going to show itself as the winter progressed. It has not.

swansong04, have you checked your oil dipstick? All will smell of gas, but unless it's way above the full mark, I would not be that concerned. However, If the gas smell in the cabin is strong, I would get that looked at.

Interesting reading the responses. My answer worked be a big fat NO...this is not a known issue. You are saying that the INSIDE of your vehicle smells like gas and that is NOT normal and I know of no one that has expressed smelling gas in the inside of their RDX. Your oil may have a hint of gas smell when checking the dip stick but you not be smelling any gas inside your vehicle. The oil dilution problem is a completely separate issue then what it sounds like you are experiencing based on your post.

I just went for a drive and got the car warm. Then came back and checked the oil. Itís smelled almost like pure gasoline. Another thing I noticed is oil seemed dirty. It had its first oil change at Acura only a few weeks ago.

That's good. It seems like you do not have the gas in oil issue then.

I've had multiple vehicles with direct injection in the last few years...

A 2016 CR-V with the 2.4L smelled like gasoline after being driven.
A 2017 Ridgeline with the 3.5L never smelled like gasoline.
A 2017 Civic Si with the 1.5T never smelled like gasoline.
A 2018 Accord with the 2.0T smelled like gasoline after being driven.
A 2019 RDX with the 2.0T smelled like gasoline after being driven.
A 2019 Ridgeline with the 3.5L doesn't smell like gasoline.

sucks when you open the hood and it smells like my 1990 Civic Si. That had 450k on it.

I didn't even have to open the hoods. Let's say I stopped at a grocery store and walked in to get milk and bananas then came back out to my car five minutes later. As soon as I started the car, the HVAC would pull the fuel odor into the cabin. It would clear out in a minute or so. If I parked the cars then opened the hoods and started sniffing around, it seemed slightly stronger on the passenger side. If I had previously set the HVAC to use recirculated air or if it chose it automatically, I wouldn't smell the fuel odor inside.

it wasn't an alarming amount of fuel odor as if gasoline were dripping from the vehicle, but closer to the level you might expect if you spilled a drop or two of fuel on your hands or clothes when refueling then got back into the vehicle.

The first few times it happened, I thought I was smelling fuel from nearby gas stations, but it continued to happen even when there were no gas stations around.

I find it ironic that the Civic, which has the 1.5T that's experiencing the fuel dilution issues, was one of my Hondas that didn't have the fuel odor. I drive a lot of different vehicles and I've only noticed this issue in relatively recent Hondas. Whatever the cause, a brand new vehicle shouldn't smell like gasoline under the hood or in the cabin. For me, it was mostly an annoying embarrassment when passengers would look at me and ask, "Do you smell gasoline?" when getting back into the vehicles and I'd answer, "Yes. I've had a few recent Hondas do that.

I couldn't agree more. a new Acura SHOULDN'T have this happening .
