I bought my 2018 LX in Nov. in Ontario, Canada. Everything is fine except the engine oil is increasing. I found this issue in last month, mileage was 2500 kilometers. The engine oil exceeded the whole plastic part of the dipstick and with strong gasoline smell.

I told this to my dealer, they reported to KIA Canada and told me no any other user reported similar problem. After I complained to KIA Canada directly, they agreeded to changing oil for free and recording engine oil consumption after driving another 1000 kilometers. Today I checked the dipstick, the oil level exceeded the F mark again.

I was wondering there is no one found this issue until now. Since in China, as I know, many people found this problem and Honda CR-V Hybrid has same issue.

Engine oil increasing with gasoline smell means gasoline leaking into oil. It is no a good thing. Even the user manual says, "Don not overfill the engine oil. It may damage the engine."

I don't want the bad thing happened on me, and to you guys neither.

Check your engine oil, if it's same as me, report to your dealer and KIA.

Hi freeczp . Not heard of this in UK and must admit had not read about China problem. Why should this be a hybrid problem rather than CEV ?. Do you know where the fuel crossover point is?

One possible reason is an injector sticking open when the engine is shut down. There will still be residual pressure in the common rail containing petrol vapour. When the engine stops - if an injector is open, the vapour will discharge into the cylinder and condense into liquid. It can then trickle past the piston rings into the engine oil.

If you believe you have gasoline in your oil, then you have a potentially explosive mixture in your engine sump that could be very dangerous if it were to ignite. Get this sorted asap!

As I know in the China market right now, Kia covers all oil changing fee if your Niro has the engine oil increasing problem.
