If you run the car in cold weather, the fuel mixture is richened to warm engine, excess fuel not burned can get into the oil. Also, if you have a car that starts hard-long cranking or has a misfire; the excess gas that is not burned will get into your oil.

AnswerYour engine has been severely flooded or, if your car has a carburetor, the float needle seat is shot. Whenever your oil smells like gasoline it's very bad for your engine. Change the oil ASAP. Answeryour engine maybe tired. you have what is called blow-by. your piston rings are not sealing on the cylinder wall. If you watch you may be using oil also. AnswerI would add the following thoughts for consideration.

Many things can cause this, some are, from a short driving cycle that doesn't allow the engine to fully warm up, to a faulty fuel pressure regulator, to leaking fuel injector/s or a carburetor float bowl being overfilled, to worn engine parts, like piston rings, valve guides, faulty spark plugs resulting in poor fuel burn ect, ect.

Basically it's gasoline getting from the top of the engine, into the bottom of the engine, where the oil sump is.

Gasoline in the oil isn't good for it, or the engine, as it dilutes the oil & robs it of it's lubricating properties, resulting in accelerated engine wear & bad engine deposits.

Best to change the oil & filter right away, review all the listed ideas & have the most likely checked out by a pro you trust.

If your cars mechanical condition is ok, but your driving cycle is short, after changing the oil & filter, try changing your driving cycle, or by taking your car on a weekly 20 mile interstate round trip, to warm the engine & oil up competely, to evaporate condensation & any gasoline that's found it's way into the crankcase oil sump.

Your ride will love you for it & the gas oder in the oil, will likely take a hike!!!!

your car is not good mechanically or u would not be getting fuel in oil. take it to a REPUTABLE mechanic and get it looked at .problem may be small and easy to fix. the longer you wait the worse it will get

gas smell in oil is caused by blow by raw fuel pasing the rings on the piston therefore getting in the oil...........bad rings Now, now... That's not very fair. Just because there's a gasoline smell in the oil doesn't mean you should go tearing your engine apart to get to the rings. Generally this problem is caused by a vehicle running way too rich (is it misfiring?) or is a problem in the fuel pump area. Don't force a rebuild just because you smell gas in the oil.

Why does your oil stick read too full?

You have either put too much oil into the engine or you may have a leak in your cylinder head gasket which is allowing coolant water into the oil - (if this is happening then you will see the water levels going down and perhaps a salad cream colored deposit collecting where you fill the engine with oil. Three conditions why the oil stick would read too full: (1) too much oil was added; (2) gasoline is getting into the oil; (3) water is getting into the oil. When you check the oil level, smell the oil for a gasoline smell or look for water beads on the dipstick and check the color of the oil. If it is chocolate-colored, there is water in the oil. In either case of gasoline or water in the oil, some repairs will have to be made. If it is just a case of too much oil, you need to drain some out.
