Hi everybody I purchased around 6 months ago a Skoda Kamiq 2021 Monte Carlo 1.5 tsi automatic from a big car dealer in London the car came only with 23.900 miles now after around 3000 miles (27100) I noticed that the oil start smelling like petrol it s not very strong but more like a medium only when I am opening the engine oil cap and I smell the cap you can feel it otherwise on cold start again you can feel it but after 5 minute the smell goes away so I think this is normal, I am just worried about the engine block and why is there smell of petrol inside of it

I have to mention the the majority of the time I am using the car for short trips 10 miles much or less I am worried that the engine might break any moment

P.S no light are showing in the dashboard once I start the engine there is just the check engine light when just the electric part is working

Hello, welcome to the forum.

How long since the last oil change?

The oil on the stick looks very light-coloured if it has not been changed very recently.

Does the oil on the dip stick smell of fuel?

Is the coolant level falling and needing topping up frequently?

Does the check engine light extinguish when the engine is running?

question

I bought the car with the oil change already done so it should have only 3100 miles on it

I didn’t smell the dipstick just the engine cap

I haven’t top up the coolant since buying didn’t look like it needed it as the temperature never went about 90* for the coolant

Yes the engine light is is off after I start the engine

A petrol smell seems to be normal with a tsi direct injection engine. My previous Superb II 1.4tsi had the same owned from near new for 10 years. It's still going strong under new ownership and a rather high mileage. I'd suggest normal.

Thank you for the advice hopefully there is no issue as I can t hear any weird noises from the engine and everything runs smoothly on it

I get a whiff of fuel now and again, I think you'll find in these cold conditions it's the auto choke working overtime. Incidentally I got a smell the other day starting up, it's really cold here and I thought I could smell paraffin as I'd fetched some in a sealed container from the shop a couple of days previously. It wasn't that, just the engine warming up on choke, I have no leaks etc. BTW it's only a very faint smell soon dissipates, my Mazda smells a little too on auto choke when started in the garage. I wouldn't worry at all, carry on driving.

With the short trips you do I don't think this is anything to worry about. If the petrol smell was there at the end of a long trip then it would be cause for worry.

The TSi engine has a cold start function with might be slightly over-fuelling the engine during start-up. The excess petrol can then mix with the oil and get into the sump. Also the engine has the ability to operate in 2 cylinder mode, this could also give rise to fuel being injected that is not burnt on occasion.

If you are worried ask for the dealer to do a diagnostic scan and report any DTC's (They will probably charge you.)

Thanks, that second picture is a lot clearer and the oil colour looks better to me.

Mines the same, Slight whiff of petrol in the oil.. On cold mornings dont let the car idle to warm up as the auto choke sends more fuel though which if left idling can create a small amount of fuel going past the piston rings and mixing with the oil in the sump.. on cold mornings clear the windscreen of frost etc and drive normally (dont drive it hard, Until it has warmed up).. Regular oil and filter changes are a must on these turbo charged cars.. Plenty of videos about this on YouTube,,, It's normal..

diesel smels like diesel, gasoline like gasoline.

When a petrol cars is diluting the oil with petrol or you suspect it is there are samples to take, test etc. Or as many might do, DIP THE OIL, take the dip stick away from the car, and use a match or lighter to move a flame near the oil on the dip stick. Petrol in Oil usually will burn. try just fresh oil and a naked flame near and see.

Hello, the litmus test is to hold a flame “away from the car” close to the oil dipstick, as it is made of metal. DPF (EURO 6D temp) was introduced in 1000 and 1500 cc cars following the 2022 restyling, and therefore only in the event of regeneration failure could gasoline be found in the engine oil, as is the case in diesel engines with diesel fuel. Certainly, in a worn engine or one with imperfect carburetion, there may be a smell of gasoline, but the engine oil level will not increase.

It's my opinion that those advocating trying to set fire to the petrol in the oil are giving dangerous advice. OK It is possible but carries some risk for the unwary or inexperienced. It's also not conclusive.

As has been said, there might be slight contamination for all sorts of reasons. If there is any sort of real problem there will almost certainly be DTC codes in the cars engine management computer which can easily be scanned.

Severe over-fuelling will give rise to particulate filter blockage, soot in the exhaust and problems with the catalytic converter. All of which will be captured in DTC codes, not to mention poor fuel consumption.

Tiny amount of oil on a dipstick, and it is the fumes coming off, about as much risk as burning brandy off a plum duff. Engage brain, and if you have not full safety gear and fire step away from naked flames. It is not conclusive, but that does not stop it being a quick test that some Resoponders to breakdowns will do ot Motor Engineers, AKA Mechanics might still carry out. Pre Plug in and read Fault Codes, or No OBD port, as was for decades.

...and years ago prior to such things as DTC codes I might have done it as well, probably did. Today I prefer a code reader.
