Oil cap smells like gas

I have a honda civic 2017, with 105k miles. I just opened the oil inlet(picture attached) , and smelled the cap. It smelled like gas. I dont think thats close to normal. But is this a common occurring ? If not, is this very bad ? Do we have a solution ? Any help is appreciated.

I also got an oil change last week itself.

It’s normal with these cards to have a little bit of gas in the oil I believe, but there has been a recall in the past for some of these models for excessive gas in oil.

If you do a lot of short distance driving or idling, I would make sure to be changing your oil more frequently. But otherwise it’s probably fine.

Make/Model specific owner forums are invaluable: https://www.civicx.com/forum/

Like Josh said, it’s probably fine. I wouldn’t trust your nose as a precision diagnostic instrument in this case, it’s hard to tell how much is in there. You could get an oil analysis done and it’ll look something like this and tell you exactly how much fuel is in your oil.

Honda’s 1.5l turbo motor is well known for gas leaking down past the rings, especially on cold-start. It’s overall a design flaw. Honda did release a ‘software patch’ that essentially tries to warm the motor up a bit faster. Once the rings are up to temp, they seal just fine. Officially they say “try to avoid short trips and make sure that at least once in a while you’re getting the car up to full operating temp”.

Does this affect '17s?
Have the impression it’s '18s+

Generally speaking, no the oil should not smell like gas. This typically indicates bad piston rings. I’m not familiar with the engine but what Adam said makes sense that it might be a design flaw. It could also be the engine is simply worn out or not well taken care of. Or all of the above.

Honestly, a lot of issues are the intersection of advertising longer oil change intervals and the switch to low tension piston rings.

I think this, and occasionally extended beyond recommended interval changes has contributed to issues with oil deposits behind the rings.

This video seems like a good source of information on the issue with this specific engine.

Geez, thanks for sharing that. I had no idea. I’m getting ready to buy a covered model from my brother.

I’ll have to do some research as I suppose it’s possible that some cars will never have the problem while others develop it very quickly (one person said after 200 miles from new).

The car is for my teenager and she’ll probably wreck it anyway. If I can get a few years out of I’d be perfectly happy.
