If that's the case I guess all of my vehicles have been malfunctioning because the oil has always smelled like fuel was in it. Even the one that got 200,000+ miles (1988 Chevy Beretta) on it's engine (2.8 liter V6) before it died due to neglect. Or maybe it's just that the oil as it gets contaminated smells like fuel is in it when it really isn't which could be the case. Eric, let us know what is said about the smell of fuel in the oil on your mom's Volvo if you guys decide to take it in. I don't have a definitive answer or fact but I say that it's highly possible for a very small amount of fuel to get by the piston rings when the engine is cold and first started. Remember, our cars run pig rich from the factory so that could aid in the problem too. Maybe I'm wrong but that's just my opinion.With the exceptions in the Q&A article I don't buy it. It's not normal to have anti-freeze, or ATF mixing in with the oil either. All the articles on this matter I have read state its not normal to have gas mixing in with the oil. I've been changing oil in my cars since 1976 and never have I ever had a gas smell in used oil or a "slick" atop of the oil.
Maybe someone can produce an article from a reputable source stating gas and oil mixing in the crank case is normal and no harm will result as a result of this?
I'd say this is nothing to worry about. It means your car went too long on that oil. Basically when your car is cold, you hear piston slap, because the hypereuetic pistons are expanding with the heat and eventually grab the cylinder walls tighter and seal up. On alot of cold starts, you will get slight blow-by on the cylinder walls letting the atomized fuel seep past the rings and get into the crank case. Enough time and eventually your oil smells like gas. Bad thing about this is gas severely lowers the viscosity of your oil and makes it very watery and ineffective. 50% oil life left = 3000 miles, ignore what GM says, synthetic is great, but not 6,000 mile great... these are performance cars, and if you drive them like that, 3,000 is when you need to change your oil.
Now, if this is a higher mileage motor, this is not uncommon. If its a low mileage motor.. might be a concern.. either way if you have some free time and patience, do a leak down test and see yoru compression... this is normally a sign of blowby.
That's hard to believe. It is a major liability (insurance) issue to have a customer in a shop when work like draining the oil, since the car is usually on a lift, is being performed. Most shops have guard rails or a chain in place to keep unauthorized people from entering the work area.I have never changed oil myself but i always stand right next to the person who does it. and have always looked around the engine and smell, Have never smelled Gasoline. And i am talking about a 96 Camry, Acura TL, 03 and 05 an Audi A4 and Corolla 05.

I believe him. Has your car ever been tuned?I dont have it in print but a buddy of mine who is a mechanic/engineer on a racing team and has TONS of experience with performance vehicles and stock cars said its just a sign that the car is running rich. He said it is nothing to worry about. You guys dont know him but I know that if he says its okay...its okay
