Hi,
Since I found that gasoline smell I took two 1-hour trips to let oil heat up properly. Gasoline smell is gone. Oil level on the dipstick is stable. I check it both cold before I start the engine, and then after I return home and let it cool off for 3 minutes. Oil level is consistent now, it's not increasing nor decreasing, both on cold and hot engine.
I took my car to Skoda authorized service center for one more checkup before making any decisions. They looked and they found there are no leaks after they cleaned oil pan and surroundings the first time I was there, 110km earlier. We looked everywhere, not a drop of oil, its completely dry now. One theory that they gave is that someone just before handing me car tried to top up oil but overdid it and when I started it for the first time, that excess went through oil separator, making the whole mess.
As for the smell of oil, they said that not one of hundreds of cars with this engine got any problems of this kind, and if this engine had real problem diluting oil with gasoline, it would mean that engine is totaled, and it's impossible for this engine to be so damaged and not give even single sign that it's internally malfunctioning. Their theory again was that car was not making any long trips since its last oil change and car seller moved car around his place for pictures, car wash, cleaning interior and similar stuff, making a lot of engine starts and immediate stops. These conditions could lead excess gasoline finding its way through piston rings and when I drove it for the first and second time it started to evaporate, making dipstick, cap stink like hell.
I was reassured that even that it might be scary as hell, and I was right to contact them, but there is nothing wrong, just put fresh oil in it and start using it.
I'll be posting updates as, at this moment, this thread is one and only place in the whole internet where there's 1.0 MPI and oil dilution even slightly mentioned. I hope that these will be just reports how many problem-free trips I'm doing, but if anything bad happens, I'll also leave it as warning.
At this point car has 62130km on odometer and works perfectly.
Wish me luck,
BR
