V6 Fuel Problem
I recently took my RS in for safety and emissions inspections.
I was told that I have about 3 quarts of extra fluid where I should only have oil, and the car is running rich. I told the techs to figure out what the extra fluid is, and where all the extra fuel is going since there's no real gas smell at the tailpipe and it's not running funny. They said that the 3 quarts of fluid is actually gas, and that one of my injectors, most likely #6 cylinder, is allowing gas out all the time, even when the car is not running. This extra gas has found its way into the oil, but no other fluids are contaminated, and it is only coming from one cylinder. Besides a busted injector, what could I possibly be looking at going wrong in the engine?

Re: V6 Fuel Problem
If you keep driving you will eventually ruin all the bearings in the motor. You also run the risk of ruining that cylinder. Excessive gas in a cylinder can seep past the piston rings washing oil off the cylinder walls. Get the oil changed and get the injectors replaced.

Re: V6 Fuel Problem
Stuck injector or multiple injectors is my guess. Is it running bad at all? You are washing down that cylinder, or multiple cylinders bad to gain 3qts of gas in the oil.
I had one get stuck wide open before, it was a 48lbs injector. So needless to say i found a exhaust leak at the manifold because gas was literally coming out and filling up the exhaust as well...lol Doesn't take much when you get into larger injectors to really make a mess fast.
If it is getting into your oil do NOT drive the car. It will ruin your bearing in a hurry. Drain out that oil asap, change the filter, and find the problem. Once you do find and fix the problem, change the oil one more time after within about 200 miles just to be sure all the gas is outta the engine where its not suppose to be.
