How much fuel will ruin this engine?

[Heavy Duty]

Hello all. I picked up my new 2021 ranger on 12/29/21 with 23 miles on it. Last weekend I changed the oil at 2600 miles because the oil read high on the dipstick and I felt an early change never hurt. I had drained out 7.4 quarts, now not exactly sure how much over filled the crankcase was from the factory, I have been monitoring the oil level every couple of days. So, now I have 2850 and the oil level has climbed from the top of the hash marks on the dipstick to the top hole. At this rate, I would be well over a quart at 5000 miles.

Should I quit driving the truck? I plan on calling the dealer tomorrow to get it in. Is this excessive compared to other brand new 2.3l ecoboosts?

I smell gas like the bogas kind.

It’s excessive! Don’t delay in getting professional help!

Yea I saw many other posts but not much concerning exactly how much fuel is too much fuel. I had a 2019 ranger (my wife's truck) that had a small bit over the 7500mile interval but this truck is a bit more.

I'm calling the dealer today and requested an oil analysis kit from blackstone.

Not sure what a tacoma has to do with this. I'm not a toyota troll. My last truck was a 2020 F-450.

i wouldnt pay much attention to the "fuel in oil" stuff. with all the electronic sensors and computer junk on new cars if something was wrong it would tell ya. the computer on the new rangers monitors darn near everything. id bet a nickel most brand new engines have a lil fuel in the oil until its broken in and things are seated well etc. if you already changed the oil and filter then great. drive it. run the truck hard. pussy footin around for 5k miles is for engines from a bygone era that are now obsolete. not saying you do that. just putting it out. im getting near 20k miles and i never checked the oil for fuel and if happens to have gas in the oil then fine by me. the truck runs like a baby daddy before child support hearings. i avg over 20 mpg even when a solid 40 % is off road with the truck loaded full of extra stuff. it pretends to be turbo diesel in terms of power and it does it pretty frugally. cant expect anything better from it. if the engine runs good and is not showing symptoms that show up while driving then it does what its supposed to do. people get over hyped when they hear something from the .00003% of owners on line and stress about it. for about a week i was dead set my center support bearing was going out. read all about it thread after thread. i stressed after hearing it making noise. took it to a mechanic who looked it over and he gave it hose down of brake cleaner (red river mud ran out) then he said nothing wrong with it. he was right. no worries friend, put a few thousand "truck use" miles on it before worrying about fuel in the oil. most likely- the rings will get broke in nicely and you will have a great engine for many years. if it goes poof its under warranty lol. as the end user consumer its not our jobs to be ford engineers or technicians or to look out for manufacture defects ? . "thats what i plan on telling the dealer when mighty mouse under the hood sends a piston through the hood at red line" . all i know as the consumer is i used it for what it was sold to me to do an now it no worky, ford fixy.

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

What if it's at 12.55?

Dangerous territory but still safe.

This is the best worst-written post I've read in a long time. . . but, I agree. LOL

As I've grown older I worry less and less about what hasn't happened yet (if at all). By yesterday's logic I trashed my engine early on by flooring it a few times or running in 4-low on some rigorous trail rides. By today's logic I did it a solid by seating the rings. My first oil change was at 10k (no sh!t!). So far no warning lights, no hiccups and it continues to deliver power on-demand (I still hate the ten-speed tranny, though).

Will it die an untimely death? I have no idea. Despite it being poorly cared for by some people's standards, any noise or quirk is still checked and repaired ASAP if needed (none so far). I'm not made of money so are these things concerning? Sure, but I just can't worry about monthly oil analysis and whatnot. If it gave me that kind of anxiety, I would just have to sell/trade it. Especially since the market seems great for that right now.

EMMV (Everybody's mileage may vary)

You won't see much about exactly how much is too much because nobody knows. Ford is (frustratingly) keeping completely mum on the subject. Blackstone says 2%, but that's not based on any engineering analysis of this or any other engine. Various forum members have come up with their own thresholds, but without any good justification.

I had a 2019 ranger (my wife's truck) that had a small bit over the 7500mile interval but this truck is a bit more.

It's possible that there's some underlying difference between the two trucks, but I'd be really interested in hearing about any differences between how your wife and you use your trucks. Does one of you have a longer commute? Drive more aggressively? Hit the trails? Go on road trips? Use different fuel? Have a tailgate damper?

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.

My 21 had oil at max fill hole at 8 miles when new. Now at 1900 miles it is about 3/8" above max fill hole. Goes in for service appointment next Wednesday.

There is a huge thread on it here:

[Rp930]

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

 

[rydfree]

What if it's at 12.55?

You should not smoke when checking your dipstick at that point .

The jokes in this thread are pretty funny.

As a side note, I only put 6qts in during my oil change for this reason. Buy myself more time before it fills up
