I took truck to dealership yesterday and was told that it is normal. So going to take your advise, Matt, and keep an eye on oil level.What Mike said.
Direct injection engines are notorious for having some fuel dilution but as long as it doesn’t get out of control to affect the oils viscosity then you’re ok. Just keep an eye on your oil level to make sure it doesn’t grow.
lol how the hell did you revive a thread from 2013. I mean I just learned a lot so im not complaining.2 things: Boost, and rings. Your ecoBoost trucks have turbos on them. Turbos force 20psi more air into the cylinders. combine that with the piston compression, and theres a lot of force on the rings. Stock rings aren't as tight as racing rings, as they're designed for 200,000 miles. they are fit a little looser to reduce friction which helps the engine to run cooler and spin more freely for less fuel consumption. these things combined will get you some fuel in your oil. now, if you're a jackass like myself, and running huge turbos and a radical tune with a giant intercooler, you may see/smell even more fuel in the oil. Full-Race has new bottom end parts if it ever gets too bad. Change that oil every 5000 and run AmsOil 5w-30
I don't know how many times, but I'm betting you are on to something.I don't think a CC is a fix all for this truck. It might help but it won't stop the blowby from mixing with the oil in the crankcase. Mainly a CC cleans the air before it goes back into the intake to help keep the valves clean. Oil dilution must be the cause of early engine failure in some trucks. How many of us watched the Ecoboost torcher test video? What I want to know is how many times did they change the oil and spark plugs in that test!
No disagreement here, it concerns me a little because I bought the truck as my main family vehicle so it gets lots of short trips. Just saying that a CC doesn't stop the blow by from mixing with the oil down in the crankcase. A CC was one of the first things I did, but if its not setup right it could restrict and slow down the crankcase ventilation making the dilution problem worse. They clean the air after it leaves the engine. Whats needed is a way to better extract those fumes before they have a chance to contaminate the oil. I've been thinking on how to add a crankcase vent down low like at the top of the oil pan. then draw in fresh air down low and suck it out both valve covers. I worked on a car that was set up similar once, think it was a fiat.Never said it was a fix all. If the engine is allowed to reach operating temperature for some amount of time, I feel a CC would condense a lot of that gasoline out of the oil. We can agree to disagree, but if you consider the vaporization curve for gasoline, that crankcase will be full of vapors just waiting to condense at operating temperature. I think the other side of the coin is how fast are you adding the gasoline to the oil? If the removal rate is close to the supply rate, then you never really change the amount of gas in the oil. Seems like the OP has moved on to a Chevy by now!
