I was wondering whether you can smell gasoline in your oil. 

 

I haven't noticed it before, however I wasn't really smelling it that much. I drive my car often on short relations. 

 

The dipstick is very difficult to use in my car because oil is all ower it, but I believe that my mechanic put too much oil few weeks ago (about 1cm over the line) . Could that be an issue? 

Pull out the dipstick, move away from the car and try lighting the oil on the dipstick.  See if it goes alight easily.

(Quite a common test carried out on the 1.4 TSI Twinchargers that could produce higher oil levels because there was petrol getting into the oil.)

 

So all the VW Group engines other than the 1.2 44kW engines are according to the owners manuals checked at 'Normal Operating Temperature / Hot. (Skoda say warm sometimes)

The 1.2 44kW engine they say is check the oil when cold.

 

?

How are you checking the oil level on the dipstick, when hot or when cold?

I checked when barely warm, because otherwise oil is sticking to the dipstick and I can't see properly. But after 5 shots I can read it. 

 

I've seen what's the max, and I'm telling you that mechanic put too much (1cm above a point). 

 

I was wondering if that could cause any damage that would contribute to gasoline smell in the oil. 

 

My main concear is whether this is normal or not. Thanx! 

Maybe once your post is moved to the Mk1 Fabia section those that know the engine you have can comment.

 

Regardless of what engine you have you had best remove the excess oil in it, or have the mechanic that over filled it do that.

I didn't put it in Fabia mk1, because I thought it's a general car topic. 

 

Still, my main question is about the gasoline smell. I'm not sure whether it is normal. 

An oil smell from oil is normal.  Maybe that smells a bit like gasoline / petrol to some, and maybe there is petrol diluting your oil.

 

So take the dipstick out with oil on it and try lighting it.

 

Then since you are having trouble reading the dip stick.

Run the engine, then stop it, remove the dip stick.  Let the engine cool and the oil all go into the sump and dip it later with a clean dipstick.

Hopefully no oil coating the dipstick tube.

Not normal.

Can't see how overfilling oil would be relevant, but that does need bringing down to a better level.

Check that the coolant temperature sensor gives plausible temperature numbers when cold and fully warmed up.

Coolant temperature sensor is good. I'm not sure how it would affect oil smell. 

 

Also, a year has passed since replacing the coolant and it didn't move a milimeter. So, everything about that is good. 

 

I noticed the gasoline smell when I went to randomly check my oil level.

 

But I remember noticing that the level is too high on the dipstick a few days ago when I changed the oil, so that's why I'm also asking if this could cause the smell problem. 

 

Could it be a bad fuel injector? 

Also, my car is often driven in the city and short relations. Is there something else I could check to gain more data?

So, it's problematic only if it lights up?

Because the sensor determines how much fuel is injected according to temp.

Oh ok. 

Well, I believe that the engine is not tuned up well in general. It's probably running rich. 

 

I can sometimes smell raw gasoline at idle. 

 

I thought that it determines the mixture based on air intake temperature and intake air pressure.

 

However, I don't see how to fix this if everything seems to be within normal values. I checked with a scan tool. 

 

Is there anything else I could check?

Yes, in conjunction with the coolant temp sensor.
