How much fuel will ruin this engine?

[txquailguy]

Put a catch can on her and call it good.....I'm betting your 2.3 Ecoboost will run great for many, many miles to come.....like Mark the Yoda said....don't pussy foot around with that engine....run her hard here and again and I'm convinced you will be please with the results.....
I've got over 70K on my '19 Ranger and she runs as good or better than brand new...

Stirrin the pot...lol

My F150s 2.7l always develops fuel dilution, and
at near 70k miles doesn't seem to be an issue.

Gets worse with long idle times in cold weather.


Make sure you take it out on the highway and give it some nice spirited driving. No need to floor it just accelerate harder than usual.

Any count of how many “ruined” engines there are because of this?

Most recent count reported is approximately “0”.

How are you driving this truck? It is my understanding that lots of short trips without getting the engine up to temp for a time may cause excess fuel in oil, especially in winter on a new engine. Running the truck at speed for 30 minutes should evaporate most of the buildup of fuel in oil. Also,
oil changes every 5 - 6K, not the 10K max.

And I am with GSD4EVR, I'm not going to worry about premature death, as long as it happens before 100K miles.

Not very short trips, especially considering 2800 miles each month. I drive a lot of highway 72-73 mph and I accelerate with a purpose, I dont beat the truck but I make the turbo do its job here and there. 300+ miles in 5 days this week and the fuel has climbed almost 1/2" on the dipstick.

Thanks.

For other replies, you guys are truly welcoming here.

this may be the solution....put a match to your breather every few days and burn off the excess

Great idea. Oil fields do it all the time.

Y’all checking your oil level daily? I don’t think I have checked mine since I changed it few thousand miles ago. Guess I should remedy that. I am
Expecting gas to come bubbling out of it when I pull the dipstick!

Not daily, but often right now just because the oil level was over an inch above the full mark on the dipstick when I did my first oil change, just found it very odd that it was that high. I checked it one other time when I initially bought the truck.

With 6qts, where was the level on the dipstick ?

How long do you let it sit before checking ?

At 6qts it was at the halfway point on the dipstick. Two weeks later, about 200 miles it was the the top of the hash mark. Haven’t checked it since due to weather but have put another 300 miles on it. When I check it in a week or so I will report back.

I've always been curious about this..

On my F150 2.7, not only do I have to wait 20 minutes for the oil to drain down(oil check valves), I find myself re-inserting and wiping the dipstick multiple times as I always get false level readings at first(Either too high or low). By the 3 or 4th removal, I get an accurate reading.

I'm assuming the 2.3 also have check valves, so how many people triple check their dipsticks after the first time around?

Personal opinion. Yes! Fuel in the crankcase can be a problem, and Ford does have a fix. But the percentage of folks having this issue is very small, regardless of what you hear!

12.6 ounces over and your toast. 12.5 and you fine.

What if it's at 12.55?

then it's toast done on one side - just like the pos toaster my wife bought - a cuisinart, worst toaster ever , have to pop the bread out and toast the undone side, and you think a little gas in the oil makes your life difficult, spend a couple days in my kitchen......

Trick I found for this is to pull stick wipe it and then leave it out for 5 to 10 minutes. This lets all the residual oil in tube drain down. Think wicking here. Then insert stick and pull and an accurate reading will appear.

Fill only 5 1/2 quarts oil gives you more room for fuel

Just leave it empty and you'll never worry about fuel in the crankcase again!

There is a mega thread on here about this. Bottom line, no one has blown an engine or had a fire because of it. From what I can tell all of these engines have a full point that is beyond the full on dipstick. After that point it self regulates level (burns off) excess blow by.

Sounds like you have enough breakin time now to set your rings. Go out and WOT her to redline. Do that like 4 times. Your levels should be better after that. I get Blackstone reports. I have <2% gas in my oil. When I started out it was Mach higher than it is now. My level sweet spot is top hole now. I got 15.5K now and it runs nice.

I will be adding a catch can though. The more crap I can extract the better. Especially the water
