Engine oil overfilled Sign In

I have a 2016 F150 2.7 ltr ecoboost motor 17200 miles, I have been taking it to the dealer to get oil changed since I got 4 free oil changes with purchase. On my 3rd oil change they double filled the engine so it had 12 quarts of oil in it. I put 2200 miles on it before I checked the level and found it overfilled. I have read on the internet that this is not good for the motor for many reasons. when I took it back to the dealer they changed the oil and filter and said drive it for 1000 miles and then bring it back to get the oil drained and filter looked at. I told them I would not be happy with it if they just come back and say there is nothing wrong with it. Fact is that we do not know when and at how many miles this will affect the engine. Anyone have any experience with oil being overfilled or anyone have any comments on what this might have done to the motor. Please respond with your comments and suggestions.


Thanks for your time

How do you know it was double filled? I find it very hard to believe you could drive it 2200 miles filled with double the oil capacity. Maybe an extra qt but I doubt it was doubled.

Same answer mostly. mhaseleu03
Who told you other than checking yourself it was "double overfilled?" Dipsticks don't tell you how much other than a "full" line and an "add" one qt. for much of anything ever.


One over could make it read way, way too high doesn't necessarily mean how much. Hey - it has to be level, shut off for a while too. Tech/dealer should have measured what came out info now apparently lost.


Yes it could damage engine quite quickly - seconds to perhaps when parked and or at a high angle way too much shows itself most.


There's no complaint it wasn't running properly ever and you were told nothing is wrong (no surprise there) so would just make note of everything and just carry on with the schedule of service as suggested.


BTW: It's been done before and the usual problem right away if that much overfilled would be wild smoke, knocking and obvious problems right away not 2,200 miles later on a guess - IMO and witnessed this stuff,

When I took it back to the dealer ship I was under the truck when we drained the oil into two jugs then measured the amount of oil. It was overfilled by 6 quarts.

Sorry, I just don't believe the engine could be driven that many miles with 6 extra quarts of oil. It would be smoking like a 3 alarm fire and leaking oil everywhere.

Well I could not believe it either but when I checked it on the dip stick and then verified it when we drained it. The motor seemed to run fine for the most part, all I noticed for noise was that it sounded like a diesel motor running at times. and I only saw smoke come out one time when I had to giver out of a drive way. That is why I am worried on what kind of damage it did to the motor. Might not see anything now but what happens at 50k miles? Seems like that is the mystery.

I would expect any issues it would cause would already have shown up. I've seen engines with as little as two quarts overfull smoke and leak all over the place. Once the oil is removed, all the pressure is relieved.

Re: Engine oil overfilled Sign In

???? There's info missing or misunderstood IMO. No way if actually 6qts. overfilled would this work so where's the missing info? It would have reacted right away as HT said - less than that much overfilled first wild smoke we've said then possible incredible knocking.
Smoke was seen by OP and noise witnessed. At best convert(s) destroyed and more. Remember or know oil is in a pan/sump the pump draws from and passively returns so it's running what might look like two qts oil low normally aggravated if so at an angle, taking off or slowing down plus turns.
Barely matters it's a truck, car or lawnmower the crankshaft splashes wildly in oil it shouldn't be touching.


Hard for me to believe it was driven over 2K miles and survived at all? Apparently did if this is true not way this didn't sustain severe damage.


I question the observations and info posted about this all around also IDK what you could do except if close to true request or demand this is trouble free now to 100K or negotiate for another whole truck.


My famous "Other" : It might not have been oil that came out rather fuel or coolant diluted with fuel or other still a total mess. Would be obvious lots quicker so end all is this doesn't add up,

PS: OMG if this was vandalism or done on purpose for some reason it still doesn't add up!
